MTRQ-4CF51 QSFP28 transceivers are designed for use in 100 Gigabit Ethernet links over single mode fiber.


The modules can convert 4-channel 25Gb/s electrical data to 4-channel optical signals, and multiplex them into a single channel for 100Gb/s optical transmission. Similarly, they opti-cally de-multiplexes a 100Gb/s input into 4-channel signals, and convert them to 4-channel output electrical data on the receiver side. It has been designed to meet the harshest external op-erating conditions including temperature, humidity and EMI interference.


A serial EEPROM in the transceiver allows the user to access transceiver monitoring and configuration data via the 2-wire QSFP Management Interface. This interface uses a single address, A0h, with a memory map divided into a lower and upper area. Basic digital diagnostic (DD) data is held in the lower area while specific data is held in a series of tables in the high memory area.
