MSOP155 SDH optical multiplexer is a kind of 19 inch 1U modular MSTP transmission device with 4* modular slots, unify (4*16=63) * 2M traditional E1 service interfaces and 4* exchange EOS 10/100BaseTx Ethernet service interfaces, and transformed to high speed STM-1 optic signal, transmitting in SDH network and MSTP network, which make it possible that high speed service and traditional TDM service can be transmitted in the same pair of fiber.

MSOP155 is easy to maintain, plug and play, and provides comprehensive network management function.

1. Provide 2* STM-1 optical interfaces, can be TM, ADM device, single/ dual fiber is optional;

2. Provide 4* modular slots, on-demand configuration. Each slot can provide 1~16* E1 physical interface, can make any configuration for E1 timeslot channel, impedance 75Ω or 120Ω is optional;

3. Provide 4 channels exchange EOS 10/100Base-Tx adaptive Ethernet interface, transparent transmit VLAN package and bandwidth control function basic on 2M timeslot channel as the particle, the maximum bandwidth is 100M, can be set to sharing mode, to achieve exchange among each port;

4. Provide 1* serial port management interface, can achieve local/remote centralized monitoring and support system upgrade;

5. Adopting large scale chip, simple circuit, low power consumption, high reliability;

6. Adapt to multi power supply environment -48VDC, +24VDC or 220VAC;

7. Standard 19"1U chassis, working stably and reliably, easy to install.
