Zyxel SFP10G-SR-E Compatible 10GBASE-SR SFP+ Transceiver

The SFP10G-SR-E covers Zyxel's short-reach 10GBASE-SR slot on enterprise switching, typically the XGS-2210 L2+ aggregation family, XGS-1930 smart managed series, and the XS-series 10G SFP+ switches. Zyxel's '-E' suffix denotes the enterprise-coded variant of the base SFP10G-SR; EdgeOptic's compatible replicates the enterprise EEPROM profile so ZyNOS and the XS Standalone firmware accept it without inventory warnings.

Electro-optical spec follows IEEE 802.3ae Clause 52 for 10GBASE-SR: 850 nm VCSEL transmitter, 850 nm PIN photodiode, dual LC, 10.3125 Gbps line rate. Guaranteed link budget of 6.1 dB supports 300 m over OM3 and 400 m over OM4, which covers the typical intra-rack and intra-floor runs on an XGS or XS deployment. The module runs across the 0–70°C commercial range and reports full DDM telemetry (SFF-8472) back to the switch, so 'show interfaces transceiver' on ZyNOS returns Tx / Rx power, bias current, voltage, and temperature per port. Power draw sits inside the SFP+ class envelope, so a fully populated XS1930-12HP or XGS-2210 uplink row does not strain the chassis rail budget even when every SFP+ cage is seated.

The module is CE / RoHS certified and compliant with the SFP+ SFF-8432 MSA so it slots into standard SFP+ cages without mechanical or electrical surprises. Because the SFP10G-SR-E is coded specifically for Zyxel, it is not interchangeable with EdgeOptic's SFP+ compatibles coded for other vendors; select the SFP10G-SR (non-E) variant if the host is a legacy Zyxel platform that rejects the enterprise EEPROM block. On the XGS-1930 smart managed line, the SFP+ uplink pair typically connects to an XS1930-series aggregation switch or to a third-party 10G backbone; either direction accepts the SFP10G-SR-E coded module provided the partner port is also 10GBASE-SR.

For mixed-fleet deployments (XGS-2210 plus XS1930-series, or mixed Zyxel and third-party aggregation), and for rollouts that combine a current ZyNOS firmware train on some chassis with an older build on others, contact our sales team with the chassis model list and the running firmware version. We will confirm the coding variant per chassis, flag any ports that need the non-E SKU instead, and quote volume pricing on matched multimode pairs.
