100GBASE-PSM4 over Singlemode Fibre

Complete Connect offer a parallel QSFP28 100GBASE-PSM4 optical transceiver module for 2 Km transmission on singlemode (SMF) fibre.
This QSFP28 optical module offers 4 independent transmit and receive channels, each capable of 25Gbps operation for an aggregate data rate of 100Gbps.
The interface is via an MTP/MPO connector and proper alignment is ensured by the guide pins inside the receptacle.
Electrical connection for the 100G PSM4 module is achieved through an MSA-compliant 38-pin edge type connector and 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 all available.
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 with this QSFP28 PSM4 optical transceiver.
The transceiver has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference. The QSFP28 100GBASE-PSM4 transceiver is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP28 Multi-Source Agreement (MSA).

All our transceivers are coded with the correct EEPROM (electrically erasable programmable read-only memory) to match your manufacturers codes. Not all manufacturers require a code, only the ones that try to tie you into buying their optics at inflated prices. Complete Connect have a professional team who are able to engineer code and new firmware releases from manufacturers to ensure we offer up to date compatibility with all major OEM, switch, router and storage device vendors.
