1, Huawei SDH optical transmission equipment uplink convergence optical board supports STM-1, STM-4 and STM-16 level SDH optical interfaces, the uplink convergence electrical interface board supports STM-1 electrical interfaces, and the downlink tributary optical board supports STM-1 SDH optical interfaces, which can be used to connect to a variety of remote equipment with standard STM-1 SDH optical interfaces, and also directly up and down the service. The tributary CD-ROM supports E1, E3/DS3, V.35, STM-1 optical interfaces, Ethernet access and aggregation, DS0 cross-connection and other functions. The whole equipment can form star, ring, tangent ring and other networks, and the branch circuit disk can also be down into a ring to construct complex network topology. It is mainly used in the communication network of large customers in the industries of electric power, finance, governmental organizations, coal mines, oil fields, substations, schools and so on.

2. Huawei SDH optical transmission equipment's convergence optical disk is a dual STM-1 network interface unit (NIU), which can be smoothly upgraded to STM-4/STM-16, and each end of the equipment has four convergence optical interfaces, which can be connected to the backbone layer of the SDH/MSTP network to converge the VC-12 services or VC-3 services of the branch directions into the upstream SDH signals, and it can also independently set up a complex transmission network. It can also independently form a complex transmission network.

Huawei SDH optical transmission equipment models include OPitxOSN1500/OSN2000/OSN2500/OSN3500/OSN7500 optical transmission equipment of the OSN series, and OPtix metro1000/metro2050/metro3000 transmission equipment of the metro series.

4, Huawei SDH optical transmission equipment configuration and price is generally based on the customer's different business needs to match accordingly, the price is not the same.
