The Fibertop 100G LR1-20km QSFP28 optical transceiver, 100G QSFP28 LR1-20(QFP-PM31HG-20DC) is designed for using in 100-Gigabit Ethernet links up to 20kmover Digital diagnostics functions are available via the I2C interface, as specifiedbytheQSFP28 MSA. The module incorporates 1 channel optical signal, on 1311nm center wavelength, operatingat 100Gbps data rate. This module can convert 4 channels of 25Gbps (NRZ) electrical input datato1channel 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 a38-contact edge type connector. The optical interface uses a Duplex LC connector. The high performancecooledEML transmitter and high sensitivity PIN receiver provide superior performance for 100Gigabit Ethernetapplications up to 20km links.
