It is a simplex SFP designed to transmit one channel of optical signal in ST 2082-1 (12G-SDI), ST 2081-1 (6G-SDI), ST 424M (3G-SDI),ST292M (HD-SDI), ST 259M (SD-SDI)through one optical fiber. These modules, including SFP, SFP+, and SFP28, are widely used in enterprise networks, data centers, and carrier-grade deployments. The SFP transceiver is compliant with the specifications the SDH/SONET/IEEE802. 3 and the Small Form-Factor Pluggable (SFP) Multi-Source Agreement (MSA) and SFF-8472. Its' reliability is benefitted by virtue of being hot-pluggable. Further, it incorporates the latest 3.
