Ideal for long-distance Gigabit Ethernet connections, backbone links, and network upgrades requiring compact, hot-pluggable fiber modules.

## Long description

The SFP module CBO EX-SFP-1GE-LX40K is a compact, hot-pluggable optical transceiver designed for single-mode fiber links. It supports a data rate of 1.25 Gbps (1250 Mbit/s) and operates at a wavelength of 1310 nm, enabling reliable Gigabit Ethernet connections over distances up to 40 km. The module fits standard SFP ports, allowing easy integration into switches, routers and other networking equipment where long-reach fiber connectivity is required.
Advantages
This SFP transceiver offers long-distance transmission capability in a small form factor, reducing the need for intermediate repeaters or additional hardware. Its hot-pluggable design simplifies installation and maintenance, minimizing network downtime during upgrades or replacements. Operating at 1310 nm on single-mode fiber gives a balance of reach and signal quality suitable for backbone and point-to-point links.
Suitable for
Long-distance Gigabit Ethernet links between buildings or data centers
Backbone and aggregation links in campus and enterprise networks
Upgrading copper ports to fiber in switches and routers
Point-to-point fiber connections requiring up to 40 km reach
Key specifications

How to use
Insert the SFP module into a compatible SFP port on your network device until it clicks into place, then connect the single-mode fiber cable with the appropriate LC connector. Ensure the device is configured for a 1.25 Gbps link speed or auto-negotiation as required by your equipment. Monitor link status indicators on the switch or router and verify end-to-end connectivity with standard network diagnostics. For safe removal, disable the port or power down the host device if recommended by the equipment vendor before extracting the module.
Usage recommendations
Use certified single-mode fiber cables and LC connectors, maintain clean connector end-faces, and follow ESD precautions when handling the module. Match fiber type and link parameters on both ends to ensure stable operation over the full 40 km range. Consult your network equipment vendor’s compatibility list if in doubt about specific switch or router interoperability.
