Microwave RTN 620 IDU RTN620
Network Application
The OptiX RTN 600 radio transmission system is a short haul digital microwave transmission system developed by Huawei Technologies Co., Ltd.
Each radio frequency (RF) carrier of the RTN 600 system can transmit 4/8/16xE1 or 1xSTM-1.
The RTN 600 can provide back haul links in a private network or a mobile telecommunication network, and can also network with optical transmission systems.
Components
The OptiX RTN 600 adopts a split structure. The system consists of the indoor unit (IDU) and the outdoor unit (ODU). An ODU is connected to an IDU through a coaxial cable.
The IDU has two types as follows:
1. IDU 610: 1U; one IF board; supporting 1+0 non-protection configuration.
2. IDU 620: 2U; one to four IF boards; supporting 1+0 non-protection configuration and 1+1 configuration.
