3-year warranty · free technical support
Coding confirmed against your switch model

The 1000BASE-ZX SFP transceiver operates at 1550 nm over single-mode fiber (SMF) with a duplex LC connector, delivering 1.25 Gbps line-rate up to 80 km. It plugs into any SFP MSA slot, is hot-pluggable, and follows the SFF-8472 management interface.

Typical deployments

Long-haul optics for cross-city backbone, rural ISP spans and inter-building runs without amplification — from tens of kilometers up to 80 km. On unusually short spans the receiver can be overloaded; ask us about attenuation if your link is well under 10 km.

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.
