Description

SDH/ MSPP Multiplexer

Introduce

Overview
As a key member of FastFOM " MetroEdge-Express" SDH/ MSPP Product family, SDH-LMFIT is a carrier-class, cost-effective, compact ( only 1U high) SDH/ MSPP platform that is designed for applications in metro and access networks to facilitate the efficient transport of traditional TDM and emerging data traffic for service providers.

SDH-LMFIT is a modularized unit with 4 universal slots, supporting different interface cards, such as STM-1 fiber optic cards, E1 cards, Ethernet cards ( EoS VCAT) , and V.35 card. The main board cross-connect capacity is 504* 504 VC-12s ( 8* 8 VC-4s) , allowing non-blocking adding/ dropping services among different interfaces. It supports the hybrid transmission of SDH, PDH, Ethernet and N* 64K V.35 services within the same equipment. With the large capacity cross-connect matrix, the SDH-LMFIT can be configured as ADM, TM, and REG. It is suitable for multiple network topologies such as point-to-point, chain, ring, hub, and mesh networks.

Features
1.4 General Slots, supporting a range of interface cards, including SDH, PDH, Ethernet and V.35 cards.
2.Ethernet service supporting GFP encapsulation, VC12 virtual concatenation ( 1~ 63 VC12)
3.Large cross-connect matrix capacity is 504* 504 VC-12s ( 8* 8 VC-4s) and powerful networking ability
4.LCD display for system configuration and alarm
5.Inter-working with popular SDH/ MSPP products of various vendors
6.Suitable for 3G access network transmission
7.Easy commissioning and maintenance
8.High integration, compact design
9.High reliability, low CAPEX and OPEX
