10Gtek's CFP4 LR4 is a 100Gb/s transceiver module for optical communication applications compliant to 100GBASE-LR4 of the IEEE P802.3ba standard. The module converts 4 input channels of 25Gb/s electrical data to 4 channels of LAN WDM optical signals and then multiplexes them into a single channel for 100Gb/s optical transmission. Reversely on the receiver side, the module de-multiplexes a 100Gb/s optical input into 4 channels of LAN WDM optical signals and then converts them to 4 output channels of electrical data.
The product is designed with the form factor, optical/electrical connection and MDIO interface according to the CFP4 Multi-Source Agreement (MSA). The innovative design has all the fibers inside the CFP4 package configured without any splicing or non-permanent connector. Also, fiber routines are neatly organized and fixed inside a stainless steel container.
