The product is an enhanced small form factor pluggable (SFP) fiber optic transceiver with digital diagnostics monitoring functionality (DDM). Compliance with Ethernet standard makes it ideally suited for 1.25Gbps data-com applications. DDM functionality (alarm and warning features) is integrated into the design via an I2C serial interface per the Multi-Source Agreement (MSA) SFF-8472, Rev. 10.4.

The transceiver supports data rates 1.25G, It provides an excellent solution for data transmission at 850nm over up to 550m multi-mode fiber. The sub-watt power consumption and excellent EMI performance allow system design with high port density.  The product is RoHS compliant and is designed and tested in accordance with industry safety standards. The transceiver is Class I Laser product per U.S. FDA/CDRH and international IEC-60825 standards.
The SFP SR transceiver connects to standard 20-pad SFP connectors for hot plug capability. This allows the system designer to make configuration changes or maintenance by simply plugging in different transceivers without removing the power supply from the host system. The transmitter and receiver DATA interfaces are internally AC-coupled. LV-TTL Transmitter Disable control input and Loss of Signal (LOS) output interfaces are also provided.

The transceiver has bail-type latch, which offers an easy and convenient way to release the modules. The latch is compliant with the SFP MSA.

The transceiver operates from a single +3.3V power supply over a case operating temperature range of 0°C to +70°C (commercial),  or -40°C to +85°C (industrial). The housing is made of metal for EMI immunity.
