5G carrier network is coming, and the key requirement of 5G network is multiplexing all service wavelengths of a base station on the premise of saving fiber resources, using the eCPRI protocol interface. 25G Ethernet is the mainstream of 5G fronthaul.

25G transceivers not only can freely substitute the corresponding channels of 10G transceivers but also can provide the simpler path to higher speeds like 100G, 200G. Now, 25G CWDM/DWDM/LWDM solution can be deployed by us to provide new requirements for the bandwidth, capacity, delay and networking flexibility of the load-bearing network.
