Network Position The OptiX RTN 900 is a new generation split microwave transmission system
developed by Huawei. It can provide a seamless microwave transmission
solution for a mobile communication network or private network.
The OptiX RTN 900 products are available in two types: OptiX RTN 910 and
OptiX RTN 950. The IDU of the OptiX RTN 910 is 1U high and supports one or
two IF boards. The IDU of the OptiX RTN 950 is 2U high and supports one to six
IF boards. The users can choose an appropriate type based on the actual
requirements.
The OptiX RTN 900 provides several types of service interfaces, facilitates
installation and flexible configuration. It can provide a solution that is
integrated with the TDM microwave, Hybrid microwave, and Packet microwave
based on the network requirements. The solution can evolve based on the
service changes that occur due to radio mobile network evolution. Thus, this
solution can meet the transmission requirements not only 2G and 3G networks,
but also future LTE and 4G networks.

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

interfaces on the EM6T always function as electrical interfaces whereas
the GE interfaces on the EM6F use the SFP modules and therefore can
function as two optical or electrical interfaces. The GE electrical
interfaces on the EM6F and the EM6T are compatible with the FE
electrical interfaces. The EM6T/EM6F accesses, processes, and aggregates four FE signals
and two GE signals. In R2 version, the backplane service bus is 1G. EM6T/EM6F support LAG function, ERPS, E-Line and E-Lan, synchronous
