QSFP28-100G-LR Single Lambda Optical Transceiver Module

The 100G QSFP28 LR Single Lambda transceiver is designed for 10km optical communication applications. Its main operating central wavelength is 1310nm, and operating at 50Gbaud data rate. The transmitter path incorporates an EML Driver and a cooled EML together. On the receiver path, the input optical signal is coupled to a Pin photodiode detector. A DSP-based gearbox is used to convert 4x25Gbps NRZ signals to 1x50Gbaud PAM4 signal. Also, a 4-channel retimer and FEC block are integrated in this DSP. The electrical interface is compliant with IEEE 802.3cd and QSFP28 MSA in the transmitting and receiving directions, and the optical interface is compliant with IEEE 802.3cd and 100G Lambda MSA with Duplex LC connector.
