Coding confirmed against your switch model

The 1000BASE-EX SFP transceiver operates at 1550 nm over single-mode fiber (SMF) with a duplex LC connector, delivering 1.25 Gbps line-rate up to 40 km. It plugs into any SFP MSA slot, is hot-pluggable, and follows the SFF-8472 management interface.

Typical deployments

A 40 km module for metro rings, ISP aggregation and inter-city links where 10 km optics fall short. Reach assumes standard G.652 single-mode fiber with clean, well-mated connectors.

Before you order

Use single-mode patch cords end to end and inspect and clean the LC connectors before mating. If your planned distance is close to the link budget, share your route details — we verify the optical budget before quoting. 3-year warranty and free technical support on every module.
