AudioCodes Mediant 800B SFP GE Long-Range Module – Single-Mode Fiber LX Transceiver for Mediant 800B SBC (M800B/SFP-GE-LX)

The AudioCodes M800B/SFP-GE-LX is a Gigabit Ethernet long-range SFP transceiver for the Mediant 800B SBC gateway. Operating at 1000BASE-LX over single-mode fiber at 1310nm, it delivers 1Gbps connectivity with a reach of up to 10km — ideal for connecting the Mediant 800B to a remote switch, router, or upstream network equipment over long fiber runs. This dual-fiber (TX and RX) transceiver is the standard choice for long-haul Gigabit fiber connections at campus and metropolitan distances.

The Telecom Spot Take

The LX SFP is the workhorse of enterprise fiber connectivity — 1Gbps over single-mode fiber at 10km covers virtually every enterprise campus and metropolitan fiber deployment scenario. Unlike BiDi transceivers, the GE-LX uses separate TX and RX fibers (a standard dual-strand patch cord), making it compatible with any standard single-mode fiber infrastructure. For Mediant 800B deployments where the gateway is physically separated from core switching by more than 100m of copper Ethernet reach, this SFP provides clean Gigabit fiber uplink. It pairs with any standard 1000BASE-LX SFP at the far end — no matched-pair constraint like BiDi modules.

Key Features
