Introduction:
M155B multi service optical multiplexer is a kind of MSTP economical access partner. It can unify the standard 2M traditional TDM service interface and 10/100BaseTx Ethernet service interface, transformed into high speed optic signal for transmission via optical fiber, which make it possible that high speed service and traditional TDM service can be transmitted in the same pair of optical fiber.
M155B is easy for maintenance, plug and play. M155B can also provide centralized local device and comprehensive network management function.
Main Feature:
1. Single, dual fiber is optional;
2. Provide 4 channels E1 digital interfaces, impedance is 75Ω or 120Ω (optional);
3. Provide 4 channels 10/100Base-Tx adaptive Ethernet interfaces, support VLAN and bandwidth limit function; the maximum bandwidth is 100M;
4. Provide 1 channel management interface, can achieve local/remote centralized monitoring, and support system upgrade;
5. Adopting large scale chip, simple circuit, low consumption, high reliability;
6. Adapt to multi power supply environment, +24VDC, -24VDC, -48VDC or 220VAC;
7. The device has small volume, light weight, working stably and reliably, convenient installation.
