QSFP+ 40GE iLR4 2 km Fiber Optic Transceivers used for Data Center Interconnect
1. Description
CY COM's OM3358FX100 is a QSFP+ transceiver module designed for 2 km optical communication
applications with single mode fiber. It is compliant with IEEE 802.3-2018 40GBASE-LR4 (partly compliant),
IEEE 802.3-2018 Annex 86A, QSFP+ 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 10 Gbps electrical data to 4-channel optical signals, and mul-tiplex
them into a single channel for 40 Gbps optical transmission. Similarly, it optically de-multiplexes a 40
Gbps input into 4-channel 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.
