SSF-SFP-MM1G 1.25G SFP Transceiver MM

The SSF-SFP-MM1G transceiver is a high performance, cost effective module supporting data-rates of 1.25Gbps and 550m transmission distance with multimode fiber.

This SFP accepts 2 LC connectors.

This SFP uses the 1000Base-SX standard, popular for short range connections.

The transceiver consists of three sections: a VCSEL laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy class I laser safety requirements.

The transceivers follow the industry standards of the SFP Multi-Source Agreement (MSA) and SFF-8472, making them directly interchangeable with any networking device following industry standards.  Note: not compatible with HP devices.
