CWDM / DWDM Equipment

Designed to build the Ethernet networks according to the SWDM technology, where intermediate nodes need a diversion of some Ethernet channels and adding the others.

CWDM technology allows you to transfer up to 8 full-duplex Ethernet streams through a single fiber. This allows to save optical fibers, increasing the efficient use of spectrum resources and to build a fiber Ethernet network under conditions of the laid fibers deficit. For input/output of individual Ethernet streams in the intermediate nodes CWDM add/drop multiplexers are used. These devices allow you to increase the flexibility of building and reconfiguring the Ethernet network. OADM are completely passive, that increases their reliability and overall network reliability.
