Microwave RTN 620 SL1 RTN620 HUAWEI SL61SL1

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.

2.1 Advanced Physical Structure

The IDU is independent of frequency.
The ODU is independent of capacity.
The interfaces between the IDU and the ODU, or the interfaces between the ODU and the antenna, are independent of their respective types.
The system adopts a uniform SDH and PDH transmission platform. The system can transmit PDH or SDH services.
The IDU adopts the design of the ADM, which makes it groom services fast.
The IDU adopts the design of plug-in boards. The two types of IDUs can share boards.

2.2 High Integration

IDU 610 dimensions: 442 mm x 44 mm x 215 mm (width x height x depth) two-layer structure
IDU 620 dimensions: 442 mm x 87 mm x 215 mm (width x height x depth) four-layer structure
ODU dimensions: < 260 mm x 260 mm x 92 mm (width x height x depth)
The power unit, cross-connect unit, and clock unit are all integrated into one board.
The control unit, auxiliary interface unit, and standby power unit are all integrated into one board.
