Product Description
Copyright © 2010 Huawei Technologies Co., Ltd. All rights reserved. Page1
Foreword
The OptiX RTN 600 radio transmission system is a split-mount
digital microwave transmission system developed by Huawei
The maximum microwave transmission capacity are 2 STM-1s.
The OptiX RTN 600 provides various service interfaces and
features flexible configuration and easy installation. The OptiX
RTN 600 can construct a radio transmission network that serves
as backhaul links for mobile communication networks or private
networks.
The OptiX 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.

IF jumper IF cable
IF Cable
Three types of IF cable in OptiX RTN 600:
IF jumper: connection between IDU and other IF cable.
1/2 inch and RG-8U cable: connection between ODU and IF jumper.
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.

ODU
Outdoor unit (ODU) realizes the
mutual conversion between IF
analog signal and RF signal
The ODU in OptiX RTN 600 can
support capacity from 2 E1s to
one STM-1.
There are 3 types of ODUs
depends on the capacity and
transmitting power.
Copyright © 2010 Huawei Technologies Co., Ltd. All rights reserved. Page12
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.
Copyright © 2010 Huawei Technologies Co., Ltd. All rights reserved. Page13
Antenna
The antenna implements the
directional transmission and
reception of RF signals. The
main parameters are frequency
band, diameter and antenna gain
Providing the dual-polarized
antenna for XPIC function
