IDM MSTP155-24 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, narrowband and other fiber optical transmission/access services, but also users’ needs for larger capacity and more reliable communication protection. It also provides succinct and faultless network management function which would carry out equipment configurating, fault-finding, data collecting and real-time monitoring on network performance. This item also features all of its components of industrial grade, comprehensive EMC and interface protection design.
