Model name: CC-CW2000

Product function: Anycan 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
300 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 etc., and the rear panel providing AC 220V / DC -48V power supply socket interfaces and power switches etc.
