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.



IDU 610/620

IDU 610

IDU 620

IDU 610 is 1U high and supports

one microwave direction.

IDU 620 is 2U high and supports

maximum four microwave

directions.


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

d 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.

7 ～ 38G Hybrid Coupler 6G Hybrid Coupler



Antenna

The antenna performs the directional transmission and

reception of RF signals. The main parameters are frequency

band, diameter and antenna gain.

Single-polarized antenna dual-polarized antenna
