OptiX RTN 600 Product Description


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.


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 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


The connection between ODU and Antenna One ODU configured for one antenna


The connection between ODU and Antenna (Cont.) Two ODUs configured for one antenna


Equipment Characteristics PDH/SDH integrated microwave transmission system. The modulation mode and link capacity are set by software. Microwave link supports the SNCP. Built-in ADM provides flexible service add/drop function. Providing the clock tracing, XPIC, MW N+1, REG and RMSP functions. Synchronous data interface and Orderwire spanning (for Ver. C SCC) Supporting removable FLASH card. Supporting AM and Hybrid Microwave
