C＆DWDM Cyclic Solution

C＆DWDM Cyclic Solution

CWDM环 CWDM loop

Our CWDM and DWDM cyclic solution can be described as following. We separate the original network into two single-fiber ring networks, and adopt the five CWDM systems to set the nodes of E, G, H, I, J. Each node has 2-channel 1.25Gbit/s data transmission to the center, and the two channels transmit the data back to back. Once one of the two channels fails, the other can continue to transmit. In this way, we fulfill the double-route function at each node, and we got a wider bandwidth and shorter switching time. This solution has the protection for three layers, including the transmission terminal, wave channel and optical path. The DWDM cyclic solution can be the imitation of CWDM cyclic solution above.
