Fiber Optic Multiplexer (PDH/FOM) SL-2000

The SL-2000 is a powerful Fiber Optic Modem, which can aggregate three types of service into a pair of fiber. Any combination of four kinds (4*E1, 4*V.35, 1*V.35, 1*10/100M Ethernet) of tributary card is allowed to plug-in the system and its maximum capacity is 16 channels E1. It supports the 1+1 hot-swappable optical protection. The SL-2000 can be managed through SNMP, VT100 craft port or LCD/menu keys. It also supports order wire function for maintenance purpose. It is 1U, 19” rack mountable or desktop type model. The SL-2000 provides local/remote loopback functions for optical and E1 interfaces. It is very convenient for network testing and maintenance. Embedded operation channel (EOC) is built between local and remote sides for system configuration, testing, performance and alarm monitoring of each E1 channel and optical link. For performance monitoring, the SL-2000 also provides BPV and CRC error count for each E1 electrical link and parity error count for optical link.
