The QSFP-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 ribbon cable with an MPO/MTP connector can be plugged into the
QSFP+ module receptacle. Proper alignment is ensured by the guide pins inside the
receptacle. The cable usually can’t be twisted for proper channel to channel
alignment. Electrical connection is achieved though a z-pluggable 38-pin IPASS connector.
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. Individual
channels can be addressed and unused channels can be shut down for maximum
design flexibility.
The QSFP-SR4 is designed with form factor, optical/electrical connection and
digital diagnostic interface according to the QSFP+ Multi-Source Agreement (MSA). 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.
