The SFP-1G-ZX is a hot-swappable, 1 Gigabit optical transceiver that operates on a single wavelength of 1550nm. The "ZX" in its name stands for "Extended Reach," denoting its ability to transmit data up to 80 kilometers (approximately 50 miles) over single-mode fiber (SMF). In an era where enterprises are rapidly expanding their network infrastructure, SFP optical transceiver modules designed for long-distance transmission have become essential. These compact, hot-swappable devices support high-speed data links across campuses, metro networks, data center. The ZX SFP module is a long-haul SFP that provides a 1000BASE-X optical connection using LC connectors and SMF cable up to 80 km long. For a complete listing of hardware compatible with these modules, see the Extreme Optics Compatibility website. Use the tables below to pick the exact 1G SFP you need—then sanity-check with the ordering checklist at the end. For 1 Gigabit Ethernet, common SFP types include 1000BASE-SX, 1000BASE-LX, 1000BASE-BX, and 1000BASE-ZX. 3 standard and Fiber Channel FC-PI Rev. The product implements digital diagnostics via a 2-wire serial bus ined in SFP MSA.
