Description
The Pronets 100G LR1-20km QSFP28 optical transceiver, 100G QSFP28
LR1-20(PQS28-31HG-PAM4) 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.
