CWDM Access System

Description

Product function: BAUDCOM CWDM Device is a sort of multi-service processing and transmission device that designed especially for point-to-point applications. It provides interfaces such as ATM, Gigabit Ethernet, STM-1/4/16 and OC-3/12/48 on the basis of a transparent transmission platform constructed by virtual fiber-optic capability enhancing devices, which can fulfill upstream/downstream transmission services at various speed including 100/155/200/622/1000/1250/2500M, and entirely increase the performance/price ratio of the optical network platform.

The device adopts a box structure of 19″ rack, of height 1U and depth 180 mm. The product can be mounted on the standard 19″ rack, with the front panel providing optical interfaces for channels and lines, working and alarm indicators, 10/100M auto-negotiating network management interfaces, RS232 network management commissioning interface etc., and the rear panel providing AC 220V / DC -48V power supply socket interfaces and power switches etc.

Features:

●   Protocol transparency: seamless connection with Ethernet, SDH network and fiber channel, including interfaces such as ATM, GIGABIT ETHERNET, STM-1/4/16 and OC-3/12/48;

●   Transparency of bit rate: auto-negotiating receiving and transmitting speed 45Mbps~2.5Gbps ;

●   Transmission distances of diversified specifications: 30km, 50km or 80km ;

●   Compact structure of 19″ rack, occupying less space and consuming less power; convenient installation and operation ;

●   Optional network management methods, providing management interfaces such as SNMP and Telnet ;
