The Link-all’s 100G LR1 QSFP28 optical transceiver, 100G QSFP28 CWDM LR1 is designed for using in 100-Gigabit Ethernet links up to 10km over Single-Mode Fiber (SMF). It is compliant with the QSFP28 MSA , 100G Lambda 100G LR1 and CAUI-4(no FEC)1 . Digital diagnostics functions are available via the I2C
interface, as specified by the QSFP28 MSA.
The module incorporates 1 channel optical signal, on 1271/1291/1331nm center wavelength, operating at 100Gbps data rate. This module can convert 4 channels of 25Gbps (NRZ) electrical input data to 1 channel of 100Gbps (PAM4) optical signal, and also can convert 1 channel of 100Gbps (PAM4) optical signal to 4 channels of 25Gbps (NRZ) electrical output data. The electrical interface uses a 38-contact edge type connector. The optical interface uses a Duplex LC connector. The high performance cooled EML transmitter and high sensitivity PIN receiver provide superior performance for 100Gigabit Ethernet applications up to long distance links.
