SFP module CBO JX-SFP-1GE-LX 1 Gbps single-mode 1250 Mbps 10,000 m

CBO JX-SFP-1GE-LX is an SFP transceiver module that provides a hot-pluggable fiber interface for 1 Gbps Ethernet links over single-mode fiber. The module supports a nominal 1250 Mbps line rate and is specified for reach up to 10,000 meters, making it suitable for long-distance connections between switches, routers and other optical network equipment. Designed for straightforward installation and interoperability with standard SFP ports, this module helps maintain continuous network operation while enabling straightforward upgrades and link extensions.

Advantages

The SFP module delivers single-mode transmission with a 10 km range, enabling long-reach connectivity without the need for signal regeneration. Its hot-pluggable form factor allows replacement or upgrades without powering down equipment, reducing service interruption. The module conforms to common SFP physical and optical interfaces, which aids compatibility with many switch and router platforms. Built to support standard 1 Gbps Ethernet, it offers predictable performance for backbone and aggregation links in enterprise and carrier networks.

How to use

Insert the SFP module firmly into an available SFP port on a compatible switch, router or optical device while the equipment is powered on, taking care to align the module with the port guide. Connect single-mode fiber with LC duplex connectors to the module, observing correct transmit/receive orientation. After physical installation, verify link status via the host device management interface and confirm negotiated speed and link health. For removal, power down the port if required by your platform or follow the vendor-recommended hot-swap procedure, then pull the module straight out using the bail or extraction mechanism.

Recommendations

Use clean, properly rated single-mode fiber and inspect connectors before mating to ensure optimal optical performance. Match transceiver parameters across link endpoints (fiber type, wavelength class and expected reach) and follow equipment vendor compatibility lists when possible. Store spare modules in protective caps and a dust-free environment to prevent contamination.
