The TQR-HGM1-85DCR is a parallel 100Gbps Quad Small Form-factor Pluggable (QSFP) optical module Recevier. It provides increased port density and total system cost savings. The QSFP28 full-duplex optical module offers 4 independent receive channels, each capable of 25.78125Gbps operation for an aggregate data rate of 100Gbps over 100 meters of OM4 multi-mode fiber.

An optical fiber cable with an MPO/MTP connector can be plugged into the QSFP28 module receptacle.

The module operates by a single +3.3V power supply. LVCMOS/LVTTL global control signals, such as Module Present, Reset, Interrupt and Low Power Mode, are available with the modules. A 2-wire serial interface is available to send and receive more complex control signals, and to receive digital diagnostic information.  

The TQR-HGM1-85DCR is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP Multi-Source Agreement (SFF-8436). It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference. The module offers very high functionality and feature integration, accessible via a two-wire serial interface.
