Brief Introduction
IDM MSAP155-24 is a newly-developed optical fiber transmission equipment by RDT company based on SDH technology. It manages to satisfy not only users’ needs for broadband, narrowbandand other fiber optical transmission/access services, but also users’ needs for larger capacityand more reliable communication protection. IDM MSAP155-24 can be directly connected to the remote PDH multiplexer, optical modem and multi-service multiplexer and so on, it fits a variety of network topologies. It can be used as a small MSAP equipment which integrates multiservice access, SDH transmission and PDH optical access functions. It also provides succinct and faultless network management functionwhich would carry out equipment configurating, fault-finding, data collecting and real-time monitoring on network performance.
