Description
The F-tone Networks 100G LR1-20km QSFP28 optical transceiver, 100G QSFP28 LR1-20(FTQ2-HG-LR1xx) is designed for using in 100-Gigabit Ethernet links up to 20km over Single-Mode Fiber (SMF). It is compliant with the QSFP28 MSA ,100G Lambda 100G LR1-20 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 1311nm 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 20km links.
