SKU CH-B7SX-3GVPV

A Gigabit single-mode optical module transmitting at 1.25 Gbps over 40 km using a 1310 nm wavelength

  • Supports Gigabit links over 40 km single-mode fibre
  • 25 Gbps data rate matches Gigabit Ethernet speeds
  • 1310 nm wavelength optimised for long-reach transmission
  • Hot-pluggable SFP form factor simplifies server deployment

Gigabit 1.25g 1310nm 40km optical module

This single-mode optical module operates at a 1.25g data rate with a 1310nm wavelength for distances up to 40km. It is designed for Gigabit single-mode fibre links in compatible networking equipment. The component suits administrators extending fibre connections between sites or buildings.

Verify SFP port and fibre type before ordering

Ensure your switch or router accepts an ESFP form-factor transceiver and supports single-mode fibre at 1310nm. Confirm the link budget matches a 40km reach and that the host device is rated for the 1.25g signalling speed. This module will not function in multi-mode ports or shorter-reach slots.
