Zyxel compatible SFP-SX-E Description

EdgeOptic's SFP-SX-E compatible is a Zyxel-coded version of the EdgeOptic 1.25G-SFP-550D multi-vendor 1000BASE-SX transceiver. It is a dual-rate SFP for Gigabit Ethernet at 1.25 Gbps (IEEE 802.3z) and 1G Fibre Channel short-wave at 1.0625 Gbps (FC-PI), using an 850 nm VCSEL transmitter and a PIN photodiode receiver over duplex multimode fiber with an LC/UPC connector.

Reach is 550 m over OM2 multimode fiber (50/125, 500 MHz·km) and 275 m over OM1. The minimum guaranteed optical budget is 7.5 dB; distance is indicative, so confirm the loss budget for the installed cabling. DDM/DOM reports optical power, temperature, and bias in real time. The module runs from a single +3.3V supply, is rated 0 to 70°C, and is built to the INF-8074i SFP MSA with CE, RoHS, and Class 1 laser compliance.

Zyxel's SFP-SX-E is a 10-unit pack of the SX optic; the optical specification is the same as the single-unit SFP-SX-D. EdgeOptic supplies this as an individual module, so you order the exact quantity you need rather than a fixed pack. The compatible is coded with Zyxel-recognized EEPROM and drops into Zyxel switches with SFP ports, and into MSA-compliant equipment from other vendors.

Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For volume quantities or deployment questions, contact our sales team.

Frequently Asked Questions

Is the SFP-SX-E different from the Zyxel SFP-SX-D or SFP-SX?

Optically they are the same SX transceiver: 850 nm, 550 m over OM2 MMF, LC duplex, DDM, 0 to 70°C. The -E is Zyxel's 10-unit pack ordering code, while SFP-SX-D is the single-unit code. EdgeOptic's compatible matches that SX optical spec and ships as an individual module, so you can order any quantity instead of a fixed 10-pack.
