40G QSFP+ SR4 100m 850nm MPO Optical Transceiver
QSFP+ 40G SR4 Transceiver module is a parallel 40Gbps Quad Small Form-factor Pluggable (QSFP) optical module. It provides increased port density and total system cost savings. The QSFP full -duplex optical module offers 4 independent transmit and receive channels, each capable of 10Gbps operation for an aggregate data rate of 40Gbps over 100 meters of OM3 multi-mode fiber.
An optical fiber cable with an MPO/MTPTM connector can be plugged into the QSFP 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 RQ-40G-SR4 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.
