LNK-OM3558SX101 is a QSFP28 transceiver module designed for 70/100m OM3/OM4 MM fiber
optical communication applications. It is compliant with IEEE 802.3 bm-2015, QSFP28 MSA standards.
Digital diagnostic management interface (DDMI) is realized by I2C interface in compliance with SFF-
8636. The module is RoHS 2 compliant.
This module can convert 4-channel 25.78125 Gbps electrical data to 2-channel optical signals, and
multiplex each into a BiDi (Bidirectional) 53.125 Gbps optical transmission. Similarly, it optically de-
multiplexes from Bidi 53.125 Gbps optical signals, and converts them to 4-channel output electrical data
on the receiver side. It has been designed to meet the harshest external operating conditions including
temperature, humidity and EMI interference.
