Fiber optic SFP transceiver CBO J4859C-BO 1250 Mbit/s LC LX single-mode 10000 m

CBO J4859C-BO is a fiber optic SFP transceiver that provides a 1250 Mbit/s data rate over single-mode fiber with an LC connector and LX wavelength. The module is designed for insertion into compatible SFP ports of switches, routers and optical equipment to establish single-mode links up to 10,000 m. It supports long-distance optical connections for backbone, metro or campus networks where a compact SFP form factor and reliable point-to-point transmission are required.

Advantages

The transceiver offers a compact SFP form factor that simplifies installation and hot-swap replacement in standard networking devices. With single-mode LX optics and LC connectivity it delivers stable signal transmission across long distances up to 10 km while maintaining a defined 1250 Mbit/s line rate. Its compatibility with a wide range of optical network equipment reduces the need for specialized modules and streamlines network spare-part management.

Suitable for

• Long-distance single-mode links between switches and routers
• Backbone and metro fiber connections up to 10 km
• Point-to-point optical uplinks in enterprise and ISP networks
• Replacement or spare module for devices with SFP slots

Key specifications

• Data rate: 1250 Mbit/s
• Optical mode: single-mode
• Wavelength/type: LX
• Connector type: LC
• Maximum reach: 10,000 m (10 km)
• Form factor: SFP (small form-factor pluggable)

How to use

Insert the transceiver into a compatible SFP port until it locks in place, then connect a single-mode fiber cable terminated with LC connectors. Ensure both ends use matching LX single-mode optics and verify link status on the networking device. If necessary, configure interface parameters on the switch or router (speed, duplex, or specific optical settings) according to the device documentation. For hot-swap replacement, remove the existing module following the equipment safety procedures and insert the new transceiver while the device is powered if the platform supports hot-swapping.

Usage recommendations

Handle the LC connector and optical interfaces with care to avoid contamination. Use dust caps when ports are unused, clean connectors with approved fiber cleaning tools, and follow manufacturer guidelines for ESD and mechanical handling. Verify compatibility with your network equipment and update device firmware if required to ensure proper recognition and performance.
