Miray’s QSFP-40G-SR4 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.
