NOTICE Indicates a hazardous situation not related to personal injury.

Safety precautions

Laser safety

The RA3P Raman amplifier emits invisible laser radiation through the line port that can

be potentially harmful to the human eye and skin.

Note: The safety information and classifications described in this section refer only to

pump laser radiation created within the RA3P Raman amplifier itself and exiting the

line port. Any external radiation (in particular the optical transmission signal) entering

the amplifier through any of the ports will exit through the other ports, and with

respect to such radiation the amplifier is considered a passive device.

DANGER

Eye hazard

Looking directly, or through a magnifying instrument (e.g. microscope), into any optical

fiber cable or connector can cause damage to the eye.

Do not look directly, or through a magnifying instrument, into any optical fiber.

1-2 8DG60013 MAAA

Issue 4 April 2010

During normal operation, when the RA3P Raman amplifier is connected through the line

port to a closed fiber transmission line, the amplifier may emit up to 700 mW of radiation

(limited by hardware). However, as this radiation is enclosed within the transmission line,

it poses no hazard. A potential hazard can occur when a fiber break or connector opening

occurs. To avoid this, the RA3P Raman Amplifier is equipped with four different

firmware mechanisms designed to detect a fiber break or connector opening, and activate

Automatic Power Reduction (APR) of the RA3P Raman pumps to reduce output power to

below the level defined for class 1M laser products

Note:When an optical cable is not attached, place a protective cap over the cable's

connector.

WARNING

Eye hazard

Invisible laser radiation may be emitted from the line port connector, or fiber connected

to this port.

Do not look into the beam or view it directly with optical instruments.

APR protection

DANGER

Eye and skin hazard

Once the product level of APR protection is disabled, the amplifier is classified as a class

4 laser product, and exposure to direct or scattered radiation may cause eye and/or skin

damage.

DANGER

Eye and skin hazard

Once the system level protection of the amplifier is disabled, the system may contain

locations classified as class 4 hazard levels, where exposure to direct or scattered

radiation may cause eye and/or skin damage.

There are two levels of APR protection, the product level and system level. The product

level APR involves only the RA3P Raman amplifier itself, and is based on detection of

the pump back reflection and Amplified Spontaneous Emission (ASE) in the short-band

(1500-1520nm for C-Band amplifiers). The product level protection ensures that opening

the line port connector of the amplifier, or occurrence of any fiber break or connector

opening in jumpers in the vicinity of the amplifier will activate APR. The RA3P Raman

amplifier product is thus classified as a class 1M laser product according to IEC

60825-1:1993+A1:1997+A2:2001, and CDRH 21 CFR 1040.10.

8DG60013 MAAA

Issue 4 April 2010

1-3

The product level of APR protection is password protected, and may only be disabled

upon pump unit provider authorization.

The second level of APR protection is a system level protection, and refers to operation of

amplifier within a communication system. When system level protection is enabled, it

allows the entire system to be classified as a class 1M system according to IEC

60825-2:1993+A1:1997+A2:2001.

Note: For more information regarding APR mechanisms, refer to chapter Automatic

power reduction (APR) (p. 2-5)

Laser radiation information

When a potential safety hazard is present (when one or both of the APR protection levels

are disabled), the following should be noted:

Maximum output power of laser radiation emitted through the line port is 29dBm

(700 mW).

Emitted wavelengths are in the C or L Bands and pump bands, rendering the spectral

range of 1420nm to 1564nm.

Beam divergence from a broken fiber or open connector is higher than 6.9 / 0.12

radians (Numerical aperture).

Beam Mode Field Diameter at the output of a broken fiber or open connector is below

11 m.

Warnings

1. Only the upper covers of the RA3P may be opened to replace fans. No other panel

should be opened for any purpose.

2. Do not try to repair the RA3P (apart from fan replacement) - Only personnel certified

by pump unit provider are eligible to repair the RA3P

3. It is forbidden for any purpose to open the Raman pump module located within the

RA3P.

4. Opening the Raman pump module within the RA3P may expose you to harmful laser

radiation. An open Raman pump module is classified as a class 4 laser product

5. Do not look directly at or through any optical magnifying instrument (e.g.

microscope) into the optical connectors.

6. When Automatic Power Reduction (APR) mechanisms are disabled, the RA3P is

classified as a class 4 laser product

7. When connecting the RA3P to a fiber line, use only connectors having Mode Field

Diameter (MFD) less than 11 m (some nonstandard special purpose connectors may

have MFD larger than 11 m).

8. For more information on safety please refer to chapter 6

2 2The RA3P Raman amplifier

RA3P Raman amplifier hardware

Distributed Raman amplification

ARaman amplifier is based on the Raman scattering process. In this process an incident

photon is scattered to a lower energy photon, while initiating a transition of the fiber

molecules between two vibration states. In the Raman amplifier, stimulated Raman

scattering produces a photon with the same wavelength, phase, and polarization as the

original signal and thus the stimulated scattering mechanism amplifies the signal. The

gain medium in the case of the distributed Raman amplifier is the silica transmission fiber

itself. Amplification occurs along a few tens of kilometers adjacent to the pump unit.

Hardware overview

The RA3P Raman amplifier contains an FPGA and micro processor-controlled Raman

pump module for C-Band (1528.4-1564.7nm) distributed Raman amplification. The pump

module includes three pump laser diodes at different wavelengths and/or polarizations. It

features multiple independent laser safety mechanisms based on Automatic Power

Reduction (APR). This allows both the RA3P Raman amplifier itself and the network

within which it is installed to be classified as class 1M laser products according to IEC

60825 parts 1 and 2, and CDRH 21 CFR 1040.10. This provides eye and skin laser

safely for the operating personnel, and also protects optical and electronic gear deployed

along the lines. The same mechanisms are used to alert system management of line

deterioration and reduction in the amplifier distributed gain.

In addition to the pump module the RA3P includes redundant user replaceable cooling

fans, as well as a communication module supporting the Small Network Management

Protocol (SNMP) through a standard Ethernet RJ45 connector.

Pump module block diagram

The following block diagram describes the main building blocks of the pump module

within the RA3P.

In counter propagating operation, the line port (through which the pump energy exits) is

connected to the output of the transmission fiber. The Raman amplified signal enters the

line port and exits through the EDFA port to an EDFA amplifier following the Raman

amplifier.

the following provides a brief description of the various detectors within the pump

module:

Detector Pes - Measures back reflected light in the pump wavelengths entering

through the line port

Detector Short Band DC - Measures ASE power within the "Short" band (1500-1520

nm for C-Band amplifiers) entering through the line port. In counter-propagating

direction the measured power also includes that of the supervisory channel, typically

located within the Short band.

Detector Short Band MOD - This detector is used only in counter-propagating

operation, and measures the modulation power of the OSC.

Detector Pump power - This detector measures the composite pump power exiting the

line port.

Detector Dpin Line - This detector measures the power within the C Band entering the

amplifier from the line Port.

Detector Dpin EDFA - This detector measures the power within the C Band entering

the amplifier from the EDFA Port.

Detector OSC forward - This detector is used in co-propagating operation, and

measures the supervisory channel power entering from the supervisory port.

Pump modes of operation

The RA3P Raman amplifier supports three operation modes:

1. Max pump power mode: In this mode maximum pump power is launched though the

line port into the transmission fiber. The Ratio between different wavelength pumps is

set according to the transmission fiber type.

2. Gain setting mode: In this mode the pump power of each wavelength is adjusted to

provide a required average gain and gain flattening according to the transmission fiber

type.

3. Manual pump power mode: In this mode the pump power for each of the pump laser

diodes can be set manually

Safety and automatic power reduction

OSC

The RA3P Raman amplifier uses the Optical Supervisory Channel (OSC) to provide for

the safety of operating personnel and to protect transmission equipment.

OSC protection ensures that the product is qualified as a class 1M device according to

IEC 60825-2. This mechanism ensures that when the transmission line fails, even tens of

kilometers from the amplifier location, the APR of the RA3P Raman pumps will be

activated.

This protection mechanism is essential for distributed Raman amplifications for the

following reasons:

Pump power launched from the amplifier line port is high, up to 700mW, which is

harmful to the human eye and skin, and can damage optical and electronic equipment.

Because the RA3P Raman amplifier is a distributed amplifier, it is possible that a loss

of input signal will not be detected, and the amplifier will not be shut down, even if a

fiber break has occurred only a few kilometers from the amplifier. This is due to large

Amplified Spontaneous Emission (ASE) generated along the transmission line within

the operating band. In lumped amplifiers this is not a problem, because ASE is only

generated within the amplifier itself.

For a detailed discussion of laser safety, please refer to section Laser safety (p. 1-2).

When APR is activated, the total pump power is decreased to below the threshold for a

class 1M laser product. For a detailed discussion of the detection mechanisms and

scenarios that lead to activation of APR, see Automatic power reduction (APR) (p. 2-5).

OSC modulation detection enables the RA3P Raman amplifier to respond to a fiber break

or connector opening which requires APR activation.

Additional RA3P Raman amplifier features

Gain flattening

Pumping the transmission fiber with two different wavelengths provides gain flattening

over C band that is better than 1.2dB peak-to-peak.

The ratio between the powers for each pump wavelength is set according to the type of

transmission fiber specified. This ratio can be fine tuned by the user.

Small polarization dependent gain (PDG)

Because the pump wavelength differs from the signal wavelength by less than 100nm, a

residue correlation between pump and signal wavelengths exists. This phenomenon is

mostly exhibited in co-propagating pumping. A polarization dependent gain (PDG) of

better than 0.3dB is achieved by using a three pump configuration, with up to 700mW

pump power, where two of the pumps have the same wavelength, but are orthogonal in

their polarization. With no polarization multiplexing, using only two pumps with different

wavelength and output power up to 450 mW, the PDG is greater than 0.6dB.

Network ready communications

The RA3P Raman Amplifier is controlled using SNMP via a standard RJ-45 Ethernet

LAN connector. The unit is supplied with a Graphical User Interface (GUI) that can be

installed on any computer connected to the LAN, or a remote computer with network

access to the LAN.

Redundant hot-swappable fans

The RA3P Raman Amplifier contains four hot-swappable cooling fans. Three of the fans

are sufficient to keep the unit within operating temperature limits. The fourth fan provides

redundant cooling capacity.

The cooling fans can be accessed and replaced through the upper covers of the unit.

Software Download

Operating software can be replaced or upgraded while the RA3P Raman amplifier is

operating without interrupting traffic passing through the amplifier, or degrading its gain.

The Software Download can be performed from a remote site via the system management

station, or through the RS232 connector on the RA3P Raman front Panel.

Automatic power reduction (APR)

Purpose

The RA3P Raman amplifier emits invisible laser radiation through the line port that can

produce eye and skin damage, as well as damage to optical and electronic equipment.

Please refer to Laser safety (p. 1-2) for detailed laser safety information.

During normal operation, when the RA3P Raman amplifier is connected through the line

port to a closed fiber transmission line, the amplifier may emit up to 700 mW of radiation.

This radiation is enclosed within the transmission line, and does not pose a hazard.

However, a hazard can occur when a fiber break or connector opening occurs. To manage

this, the RA3P Raman Amplifier is equipped to use OSC to detect a fiber break or

connector opening, and activate the APR of the RA3P Raman pumps reducing output

power to below the level defined for class 1M laser products.

This system level protection deals with operation of the amplifier within a communication

system. When this system level protection is enabled, it allows the entire system to be

classified as a class 1M system according to IEC 60825-2:1993+A1:1997+A2:2001.

OSC detection

The RA3P Raman amplifier continuously monitors the OSC signal. Loss of the signal

indicates an open connector or fiber break.

When a single direction is cut on a span containing Raman amplifiers, the Raman

amplifier on the node ingress from span where there is fiber cut (Raman [B]), will see

OSC loss. Its pumps will be turned off. However, Raman (A) on the side where there is

no fiber cut, does not see OSC loss and does not turn the pumps off. Raman packs are

completely dependent on OSC loss for APR.

APR scenarios

The OSC, identified in OSC (p. 2-3), is used to detect various scenarios that require the

activation of product and system level APR. Some scenarios are specific to either

backward counter propagating configuration (BWD), or forward co-propagating

configuration (FWD), the rest are relevant to both configurations.

OSC can be configured by the user according to the specifics of the transmission system

within which the RA3P Raman amplifier is installed.

The Alcatel-Lucent RA3P Raman amplifier is designed for backward operation only. The

relevant APR scenarios are shown in the following table.

Table 2-1 APR scenarios

If the modulated OSC signal (1500-1520nm) power < -43dBm the

amplifier shuts down. The amplifier can restart if the modulated OSC

signal power > -42dBm.

7OSC Band Low

If optical power in OSC band (1500-1520nm) is 2dB lower than value

anticipated for the given fiber type, the amplifier shuts down.

5OSC Band

Transient

If back reflection power in OSC Band is changed by a rate faster than >

1dB/150 msec, shut down occurs.

Automatic return from APR shut down

Two possible scenarios can automatically restart the RA3P :

1. When the RA3P detects a modulated OSC signal with power > -42dBm.

2. When the RA3P detects continuous wave (CW) power in OSC band > -52dBm.

If the RA3P turns on, and one of the reasons for APR still exist, it will shut down again

within 150 msec.
