Copyright © 2006 Huawei Technologies Co., Ltd. All rights reserved. Page 2Page 2
Foreword
OptiX RTN 600 is a PDH/SDH integrated short-haul
digital microwave transmission system developed by
Huawei.
The maximum microwave transmission capacity is
STM-1.
The system provides the backhaul transmission link in
the mobile communication system or private network,
and also networks with optical transmission
equipments.

IDU
Indoor unit (IDU) realizes the
mutual conversion between
the service signal and IF
analog signal. Two types of
IDU are available:
IDU 610 is 1U high and
supports one microwave
direction.
IDU 620 is 2U high and
supports maximum four
microwave directions.

IF transit jumper IF cable
IF Cable
The IF cable provides -48V power for ODU and transmits the IF signal and ODU management signal between IDU and ODU.
Three types of IF cable in OptiX RTN 600: IF jumper: connection between IDU and other IF cable.
1/2 inch and RG-8U (1/4 inch) cable: connection between ODU and IF jumper.
RG-8U (1/4 inch) cable is used for the distance less than 180 meter.
1/2 inch cable is used for the distance between 180m and 300m.

ODU
Outdoor unit (ODU) realizes the
mutual conversion between IF
analog signal and RF signal.
ODU is irrelevant to the
microwave transmission
capacity. An ODU of the OptiX
RTN 600 can support the
transmission capacity from 4
E1 to one STM-1.
Copyright © 2006 Huawei Technologies Co., Ltd. All rights reserved. Page 11Page 11
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.

PDH Microwave Overhead When the IF board is set as PDH mode, such as 4E1/8E1/16E1,
the DCC, order wire, and asynchronous transparent data
interface can only use one byte.
When the IF board is changed from STM-1 mode to PDH mode, if
the transparent transmission setting of DCC byte occupies the
D1 byte, the manual modification is required. Set the working
mode to DI mode first. Otherwise, when the IF board is changed
to the PDH mode, the DCC is interrupted.

Installation Control the quality of installation
1. The quality of IF connector
2. Water proof of the IF interface on ODU
3. The installation of ODU
4. Pay more attention to the polarization of the
ODU/antenna and coupler.
5. The main OUD must be installed on the main interface of
the ODU, and the standby OUD must be installed on the
standby interface of the ODU.
6. After the alignment of antenna, you must be sure the
antenna is locked.
