Trade Association, a non-profit industry association devoted to the promotion of and

growth of the market for IEEE 1394-compliant products. Participants in Working Groups

serve voluntarily and without compensation from the Trade Association. Most

participants represent member organizations of the 1394 Trade Association. The

specifications developed within the working groups represent a consensus of the

expertise represented by the participants.

Use of a 1394 Trade Association Specification is wholly voluntary. The existence of a

1394 Trade Association Specification is not meant to imply that there are not other ways

to produce, test, measure, purchase, market or provide other goods and services related to

the scope of the 1394 Trade Association Specification. Furthermore, the viewpoint

expressed at the time a specification is accepted and issued is subject to change brought

about through developments in the state of the art and comments received from users of

the specification. Users are cautioned to check to determine that they have the latest

revision of any 1394 Trade Association Specification.

Comments for revision of 1394 Trade Association Specifications are welcome from any

interested party, regardless of membership affiliation with the 1394 Trade Association.

Suggestions for changes in documents should be in the form of a proposed change of text,

together with appropriate supporting comments.

Interpretations: Occasionally, questions may arise about the meaning of specifications in

relationship to specific applications. When the need for interpretations is brought to the

attention of the 1394 Trade Association, the Association will initiate action to prepare

appropriate responses.

Comments on specifications and requests for interpretations should be addressed to:

4 HPCF Requirement

This clause defines a new media and connectors in order to support the automotive requirements. This new class of

unique HPCF automotive connectors and cable contained in this clause will be defined for implementation within

ground vehicles. The connector interface is useable from S200 to S800 dependent on the fiber and optical

transceiver capabilities.

The products defined in this clause shall meet Class 1 Eye Safety requirements without requiring ―Open Fiber

Control‖ monitoring circuits.

Eye safety requirements are specified in the IEC-60825-1.

Laser eye safety is a measure of how vulnerable the eye is to damage from a particular laser source. This

vulnerability is primarily affected by the output power and wavelength (color) of the laser light. Class 1 laser

devices are the safest and Class 3 laser devices are the least safe.

4.1 Performance Criteria

4.1.1 Embedded Network

The power budget has loss allocations for HPCF cable, coupling of interconnects, bends through a minimum

specified radius, temperature aging of the transceivers and the optical fiber along with system margin.

10 meters

Table 4-1: Number of Maximum Inline HPCF Connections

4.1.2 PMD block diagram

For system conformance, the PMD sublayer is standardized at the following points:

- The optical transmit signal is defined at the output end of a 1m patch cord (i.e., TP2) of a type

consistent with the connection type connected to the transmitter receptacle defined 4.2.

- The optical receive signal is defined at the output of the cable plant (i.e., TP3) connected to the

receiver receptacle also defined in 4.2.

TP1 and TP4 are standardized reference points for use by implementers component conformance. The electrical

specification of the PMD service interface (i.e., TP1 and TP4) are not system compliance points (as they may not be

ready testable in a system implementation).

The HPCF core shall be protected within a cylindrical cavity in both the HPCF inline cable plug and socket to

prevent damage to the end faces when contacted to a flat surface. The cylindrical cavity prevents optical surface

from getting damages. A dust cover or boot should be used to prevent damage during shipping and handling prior to

final assembly.

4.1.4 HPCF Cable

The HPCF cable must function within and in vehicle automotive environment with the following minimum to

maximum temperature ranges:



Table 4-4: HPCF Cable Class

The HPCF cable shall have a step index core of glass. The HPCF cable core diameter shall be 200 ± 5µm and the

clad diameter shall be 230 +0/-10µm with an Effective Numerical Aperture (NA) 0.37 ± 0.02. The HPCF cable

construction may be either single or dual jacketed and single or duplex core.

A minimum permanent bending radius of 15mm shall not affect cable performance. The attenuation change shall be

within ±0.5dB from initial attenuation after exposing to environmental tests which are performed based on

performance groups B, C and D.

Depending on the specific requests of the implementer, the HPCF cable supplier(s) may be required to provide the

additional performance data. This data may include spectral attenuation, test procedure IEC 60793-1-40, numerical

aperture, test procedure TIA/EIA-455-7, bandwidth, test procedure IEC 60793-1-41. These tests have not been

included in this specification.

4.1.5 Fiber Optic Transceiver

The FOT is incorporated into the HPCF header socket. A reference performance validation sequence is provided to

assist in the connector manufacturer‘s qualification of FOT devices to minimize risk in the integration with the

header.

The fiber optic transceiver shall be capable of working in both a 3.3 ± 0.3Vdc and/or 5.00 ± 0.25Vdc voltage

systems.

The fiber optic transceiver shall have a minimum extinction ratio of 5dB with a maximum overshoot of 25%.

The fiber optic transceiver shall be capable to couple or receive the required optical power in or out of a fiber, when

the center of the end face is located inside the green area which is described in Fig 4-2. The center wavelength @

25ºC shall be 850nm with a maximum spectral width (FWHM) of 10nm. The minimum launch power at TP2 shall

be -6.5 dBm OMA over the temperature range of the class of the HPCF header. The maximum launch power shall

be compliant with IEC-60825-1over the temperature range of the class of the HPCF header.

The fiber optic receiver shall have a minimum receiver input power of -15.4 dBm OMA at TP3 and shall receive the

maxim launch power of the fiber optic transmitter. Temperature range is based on the class of the HPCF header with

integrated FOT.

A reference of the power budget diagram is shown in Annex A.

4.3 Performance Validation

Table 1 in ANSI/EIA 364-D(01)shows operating class definitions for different end use applications. The test specifications follow the recommendations for environmental class G2.1 that defines ―Year round exposure to heat, cold, humidity, moisture, industrial pollutants and fluids‖. The Equipment Operating Environmental Conditions shown for class G2.1 are modified for: Temperature from -40ºC to +85ºC. Class 1.3 further describes as operating in maximum humidity of 95% a ―harsh environment‖. Marine atmosphere is not anticipated in this implementation.

Samples sizes have determined based on a standard known sampling procedure.

Unless otherwise specified, all measurements shall be made within the following ambient conditions:

a. Temperature: 18ºC to 28ºC

b. Atmospheric pressure: 86kPa to 106kPa

c. Relative humidity: 25% to 75%

Special tests may require tighter control of conditions and are specified in the test procedure.

This standard utilizes VCSEL FOT, for reference, and therefore does not require return loss or reflectance

measurement in the testing sequence. If an FOT, other than an VCSEL is chosen, the implementer may request the

supplier(s) to provide additional data. This data may include Return loss or reflectance performance data using either

IEC 61300- 3-6 or ANSI/TIA/EIA 455-107-A(99)test methods.

Depending on the specific location of the embedded network, the implementer may request the HPCF supplier(s) to

provide the additional environmental performance data. Salt Spray, test method ANSI ANSI/TIA/EIA 455-16-a(91),

and Corrosive Environment, test method ANSI/EIA 364-65-A(98). The environments may include.

5 AGF Requirement This clause defines a new media and connectors in order to support the automotive requirements. This new class of

unique AGF automotive connectors and cable contained in this clause will be defined for implementation within

ground vehicles. The connector interface is useable from S200 to S800 dependent on the fiber and optical

transceiver capabilities.

The products defined in this clause shall meet Class 1 Eye Safety requirements without requiring ―Open Fiber

Control‖ monitoring circuits.

Eye safety requirements are specified in the IEC-60825-1.

Laser eye safety is a measure of how vulnerable the eye is to damage from a particular laser source. This

vulnerability is primarily affected by the output power and wavelength (color) of the laser light. Class 1 laser

devices are the safest and Class 3 laser devices are the least safe.

5.1 Performance Criteria

5.1.1 Embedded Network

The power budget has loss allocations for AGF cable, coupling of interconnects, bends through a minimum

specified radius, temperature aging of the transceivers and the optical fiber along with system margin.

Number of Maximum Inline AGF Connections

Maximum Node-to-Node

Total Distance

3

10 meters

Table 5-1: Number of Maximum Inline AGF Connections

5.1.2 PMD block diagram

For system conformance, the PMD sublayer is standardized at the following points:

- The optical transmit signal is defined at the output end of a 1m patch cord (i.e., TP2) of a type

consistent with the connection type connected to the transmitter receptacle defined 5.2.

- The optical receive signal is defined at the output of the cable plant (i.e., TP3) connected to the

receiver receptacle also defined in 5.2.

TP1 and TP4 are standardized reference points for use by implementers component conformance. The electrical

specification of the PMD service interface (i.e., TP1 and TP4) are not system compliance points (as they may not be

ready testable in a system implementation).

5.1.3 AGF Connectors

Three AGF connectors are used to connect the embedded devices: a AGF header with an integrated fiber optic

transceiver (FOT), AGF inline cable plug and a AGF inline cable socket. All must function within and in vehicle

automotive environment with the following minimum to maximum temperature ranges:



Table 5-2: AGF Header with Integrated FOT Classes



Table 5-3: Inline AGF Cable Plug and Socket Class

Either an integrated or discrete ferrule design shall be the option of the manufacturers. Each mated connector pair

must withstand 20 mating and unmating cycles. A locking mechanism is employed to retain the plug and socket.

Safe disconnect shall occur without damage to either the latching mechanism or the AGF fiber. The maximum

insertion force of the mated connectors is 45N, and the locking mechanism shall have minimum pullout strength of

100N.

The AGF cable shall have minimum single core pullout strength from the AGF cable connectors of 60N, pulling

only one of the two AGF cores. This requirement applies to both the AGF inline cable plug and AGF inline cable

socket connectors.

Insertion loss of an inline connector shall be equal to or less than 2.5dB. See the TA document 2001018 for

connector requirements.

The AGF core shall be protected within a cylindrical cavity in both the AGF inline cable plug and socket to prevent

damage to the end faces when contacted to a flat surface. The cylindrical cavity prevents optical surface from getting

assembly.

5.1.4 AGF Cable

The AGF cable must function within and in vehicle automotive environment with the following minimum to

maximum temperature ranges:



Table 5-4: AGF Cable Class

The AGF cable shall have a grated index core of glass. The AGF cable core diameter shall be 50 ± 3µm and the

clad diameter shall be 125 ±2µm with an Effective Numerical Aperture (NA) 0.20 ± 0.02. The AGF cable

construction may be either single or dual jacketed and single or duplex core.

A minimum permanent bending radius of 15 mm shall not affect cable performance. The attenuation change shall

be within ±0.5dB from initial attenuation after exposing to environmental tests which are performed based on

performance groups B, C and D.

Depending on the specific requests of the implementer, the AGF cable supplier(s) may be required to provide the

additional performance data. This data may include spectral attenuation, test procedure IEC 60793-1-40, numerical

aperture, test procedure TIA/EIA-455-7, bandwidth, test procedure IEC 60793-1-41. These tests have not been

included in this specification.

5.1.5 Fiber Optic Transceiver

The FOT is incorporated into the AGF header socket. A reference performance validation sequence is provided to

assist in the connector manufacturer‘s qualification of FOT devices to minimize risk in the integration with the

header.

The fiber optic transceiver shall be capable of working in both a 3.3 ± 0.3Vdc and/or 5.00 ± 0.25Vdc voltage

systems.

The fiber optic transceiver shall have a minimum extinction ratio of 5dB with a maximum overshoot of 25%.

The fiber optic transceiver shall be capable to couple or receive the required optical power in or out of a fiber, when

the center of the endface is located inside the green area which is described in Fig 5-2. The center wavelength @

25ºC shall be 850nm with a maximum spectral width (FWHM) of 10nm. The launch power at TP2 shall be -7.1dBm

OMA over the temperature range of the class of the AGF header. The maximum launch power shall be compliant

with IEC-60825-1over the temperature range of the class of the F header.

The fiber optic receiver shall have a minimum receiver input power of -15.4 dBm OMA at TP3 and shall receive the

maxim launch power of the fiber optic transmitter. Temperature range is based on the class of the AGF header with

integrated FOT.

A reference of the power budget diagram is shown in Annex B.

5.1.6 Materials

Material used to manufacture the AGF header with integrated FOT connectors must be capable of withstanding

typical industry soldering processes. Thermoplastic materials used for the AGF connectors and cable shall have a

flammability rating of ―HB‖ or higher according to UL 94 or IEC 60695-11-10.

All AGF connector and cable materials shall not have their performance affected by:

Automotive fluids (engine coolants, transmission fluid, brake fluid, windshield washer fluid, alcohol based

fuels, diesel fuels, etc.) and

Commercial fluids (coffee, cola, alcohol and ammonia based cleaners, hand lotion, etc.)

5.1.7 Automotive Jitter Requirement

Numbers in Table 5-5 represent high-frequency jitter. Transmitters and receivers shall meet the normative values

highlighted in bold and underscored. All other values are informative. Jitter shall measured as defined in Annex N of

IEEE Std. 1394-2008. A jitter tolerance is also specified as IEEE Std 1394-2008.

Annex A (informative)

Example of system power budget for HPCF

The optical power budget requires a differential of 8.9dB between the optical transmitter and receiver port at a

reference distance of 10 meters. The optical power budgets are typically specified from/to the fiber optics

transceiver attachment points to the printed circuit board at both ends. This method is not utilized within the

specification since it does not guarantee power levels at the connector interface. For reference, 8.9dB transceiver-to-

transceiver power budget was used when determining the 8.9 dB power budget requirement specified below. This

guarantees operability between all optical devices of the IDB-1394 HPCF embedded network.

A.1 Theoretical Total Power Budget

S800 operation (Frequency of 1,000 M board)

Mean Launch Power (OMA): Pf = -6.5 dBm

Minimum FOT Input power(OMA): Pin = -15.4 dBm

Minimum Power Budget: Budget = |Pin-Pf| = 8.9 dB (1)

A.2 HPCF Cable

Maximum HPCF Cable Loss: 0.02 dB/m (2)

A.3 In-Line HPCF Connector

Maximum Loss in each Inline HPCF Connector Pair 2.5 dB (3)

A.4 Bending, etc.

Maximum Loss of HPCF Cable for Bending (R15mm, 4 turns) 1.2 dB (4)

A.5 System Margin (Two Inline HPCF Mated Connectors and 9 Meter Total Length of HPCF Cable)

System Margin = (1) –{[(2) x 9meters] + (3) + (4) }

= 8.9 – {0.02 x 9 + 2.5 x 2 +1.2}

= 2.52 dB

Annex B (informative)

Example of system power budget for AGF

The optical power budget requires a differential of 8.3dB between the optical transmitter and receiver port at a

reference distance of 10 meters. The optical power budgets are typically specified from/to the fiber optics

transceiver attachment points to the printed circuit board at both ends. This method is not utilized within the

specification since it does not guarantee power levels at the connector interface. For reference, 8.3dB transceiver-to-

transceiver power budget was used when determining the 8.3 dB power budget requirement specified below. This

guarantees operability between all optical devices of the IDB-1394 AGF embedded network.

B.1 Theoretical Total Power Budget

S800 operation (Frequency of 1,000 M board)

Mean Launch Power (OMA): Pf = -7.1 dBm

Minimum FOT Input power(OMA): Pin = -15.4 dBm

Minimum Power Budget: Budget = |Pin-Pf| = 8.3 dB (1)

B.2 AGF Cable

Maximum AGF Cable Loss: 0.01 dB/m (2)

B.3 In-Line AGF Connector

Maximum Loss in each Inline AGF Connector Pair 2.5 dB (3)

B.4 Bending, etc.

Maximum Loss of AGF Cable for Bending (R15mm, 4 turns) 0.6dB (4)

B.5 System Margin (Two Inline AGF Mated Connectors and 9 Meter Total Length of AGF Cable)

System Margin = (1) –{[(2) x 9 meters] + (3)x2 + (4) }

= 8.3 – {0.01 x 9 + 2.5 x 2 + 0.6}

= 2.61 dB
