Foreword

The OptiX RTN 600 is a split-mount digital microwave

transmission system developed by Huawei. RTN 600

provides various service interfaces and features flexible

configuration and easy installation. It can construct a radio

transmission network that serves as backhaul links for mobile

communication networks or private networks. The RTN 600

can also construct a hybrid network that is used to transmit

SDH, PDH, and Ethernet services together with the OptiX

series optical transmission products of Huawei.

IDU

� The IDU is the indoor unit of an OptiX RTN 600 system. It

accesses services, and performs multiplexing/de-

multiplexing and IF processing of the services.

� The OptiX RTN 600 IDU is available in three types: IDU

610, IDU 620, and IDU 605.

IF Cable• The IF cable provides -48V power for ODU and transmits the IF signal and

ODU management signal between IDU and ODU.

• The IDU and ODU are connected by IF jumper and IF Cable:

� IF jumper ：The IF jumper is a 2 m RG223 cable. The IF jumper uses a TNC

connector at one end to connect to the IF board, a type-N connector at the other

end to connect to the IF cable.

� IF Cable：Both end are type-N connector, one end to connect to IF jumper, the

other end to connect to ODU. There are two types of IF Cable: RG-8U and 1/2

inch.

� RG-8U cable is used for the distance less than 180 meter.

� 1/2 inch cable is used for the distance between 180m and 300m.

IF transit jumper IF cable



ODU

� Outdoor unit (ODU) realizes the

mutual conversion between IF

analog signal and RF signal.

6G ODU 7~38G ODU



Hybrid Coupler

� When two ODUs share one antenna, the ODUs must be

connected to an RF signal coupler/ splitter (hybrid coupler).

Then, the hybrid coupler is connected to the antenna.

Antenna� The antenna performs the directional transmission and reception

of RF signals. The main parameters are frequency band,

diameter and antenna gain.

IDU 605 Signal Processing Flow

� IDU 605 not support build-in ADM function, the signal need

not through the cross-connect process, multiplexes E1

service signals into microwave frame signals directly. The

signal processing flow as following:



IDU 605 Clock Characteristics

�The clock tracing needn’t to be configured. It is auto-Negotiation,

and clock tracing as the following results:

�In a point-to-point network which the NE use IDU 605, the clock

trace auto-negotiation result is the high site NE as free-run

modes and the low site NE trace the high site clock sourse.

�One site that the NE use IDU 605, the opposite site that the NE

use IDU 620, the result of clock trace is the IDU 605 ‘clock trace

the IDU 620’s clock source.

�Note：The IDU 620’ clock cannot be set to trace the IDU 605’ clock. Otherwise

the clock will self-lock.



IDU 605 Other Characteristics

� Supports the setting of the impedance of E1 signals through

the software (75-ohm or 120-ohm).

� Supports 1+1 protection for the input power.

� Supports the group call function of the orderwire, the group

number is 888. The orderwire number also can be set as

designing.

IFX Board－XPIC features

� XPIC (Cross-polarization interference cancellation ) is a

technology used together with co-channel dual-polarization

(CCDP). The application of the two technologies doubles the

wireless link capacity over the same channel.

� XPIC is used to effectively improve the transmission capacity and

the utilization of the frequency spectrums. It is widely used in the

trunk microwave. As the split-mount microwave develops and the

frequency resources become insufficient in recent years, the

XPIC technology is applied in the split-mount microwave.



IFX Board－XPIC features （Cont.）� Dual-polarized antenna：：：：A dual-polarized antenna can transmit and

receive RF signals on the two polarizations at the same time. Only one

RF interface exists at the rear end of a uni-polarized antenna, of which

the polarization orientation can be adjusted. Two RF interfaces, however,

exist at the rear end of a dual-polarized antenna. By default, the

polarization orientation of the left interface is vertical, and the polarization

orientation of the right interface is horizontal.

� OptiX RTN 600 can configure as one XPIC working group through use

two IFX board, two ODU, one dual-polarized antenna. The XPIC cable is

used to transmit the reference IF signal between the two IFX boards of

the XPIC working group, process the dual polarization signal at the same

time.

� An XPIC system has two configuration modes: single-NE configuration

and dual-NE configuration



IFX Board－XPIC features （Cont.）

� Typical configuration of XPIC (single-NE configuration)




� Typical configuration of XPIC (dual-NE configuration)




Installation Limitations ：：：：

� Only IDU 620 is applicable.

� The ODU must adopt the separate mount mode, because the dual-polarized

antenna is used.

Configuration Limitations :

1. The link ID-V and link ID-H should be difference.

2. XPIC supports the STM-1 microwave working mode only ；The transmit power

and frequency of the two ODUs that are in an XPIC working group should be the

same ；It is recommending the ATPC is disable, each of the ATPC parameters

(ATPC enable status, ATPC upper threshold, ATPC lower threshold, and ATPC

adjustment) should be set to the same value if the ATPC set to enable.

3. Make sure the XPIC cable be connected correctly to realize the XPIC function.




� When two IFX boards that form an XPIC protection group are

installed on an IDU, you can create an XPIC protection group to

ensure that the XPIC protection group is configured with the same

working mode, transmission frequency, transmit power, and ATPC

attributes.

� IFX can work in XPIC-enable state (The XPIC Enabled parameter

must be set to Enabled );it can also work in XPIC-disable state.

� XPIC-enable state：The two IFX boards from the XPIX system

are connected by an IF jumper for transmitting the XPIC

cancellation signal to each other.；

� XPIC-disable state ：IFX board can be connect to IF1 in the STM-

1service, but it is not recommended .



IFX Board －XPIC and 1+1 Protection

The four IFX boards in two XPIC working groups can form two 1+1 protection

groups, and the both IF boards from the XPIC working groups must be the main

boards or the back boards in 1+1protection groups



XPIC Cable

Figure 1：single-NE configuration Figure 2：dual-NE configuration

XPIC Cable has three types：short-line、long-line (short)、long-line (long).

Commonly，the typical configuration ：

2、Two long-lines (short) or two long-lines (long)

SCC Board -- NM Cable Connection

� The SCC board sets the NE ID through the software. The initial NE ID

is set to 49136 by default.

� The IP address of NE is also set through the software. The IP address is

set to 129.9.0.ID by default.

SCC Board －DCC Channel

� When the IF1A/B board transmits PDH microwave signals less than

16xE1 signals, the IF1A/B board always uses byte D1 as the DCC

channel.

� When the IF1A/B board transmits 16xE1 PDH microwave signals, the

IF1A/B board uses bytes D1-D1 or D1- D3 as DCC channels through

software auto-negotiation instead of manual configure.

� When the IF1A/B board transmits PDH microwave signals more than

16xE1 signals, the IF1A/B board always uses bytes D1 to D3 as DCC

channels.

� The microwave ports of the IF0A/B board and IDU 605 always use bytes

D1 to D3 as DCC channels.

� SDH line ports generally use bytes D1 to D3 as DCC channels. It also

can use D1-D1、D4-D12、D1-D12 as DCC channels.

ODU－Interface

6 GHz SP series ODUs are coaxial interfaces

7–38 GHz ODUs are waveguide interfaces

The ODUs are classified into the ODU with the waveguide interface and the ODU

with the coaxial interface according to the type of the antenna interface of the ODU.
