The SO-QSFP-ESR4 is a QSFP+ (Quad Small Form-factor Pluggable Plus) transceiver for IEEE Std 802.3ba compliant 40 Gbps Ethernet applications such as inter- and intra-connect within and between data centers between switches| routers| storage equipment etc. The SO-QSFP-ESR4 converts 4x 10 Gbps flows into four channels at 850nm over a ribbon-fiber connection.
The SO-QSFP-ESR4 is SR4 compliant but exceeds the SR4 distance performance by bridging up to 400m over an OM4 MultiMode (MM) fiber.
The transceiver provides digital diagnostic functions via a 2-wire serial interface as defined by the SFF-8472 specification. The SO-QSFP-ESR4 provides transport over an MPO/MTP 12 or 8 ribbon fiber cable.
