Fiber optic SFP transceiver CBO J4859B-BO 1250 Mbit/s LC LX

CBO J4859B-BO is a BlueOptics fiber optic SFP transceiver designed for single-mode links with an LC connector and LX wavelength type. The module supports a data rate of 1250 Mbit/s and is intended for point-to-point connections in network equipment such as switches, routers and media converters. Its compact SFP form factor allows hot‑swappable installation and simple integration into standard SFP ports to extend network reach or replace compatible optical modules.

Advantages

The SFP transceiver offers a standardized small form‑factor that supports easy replacement and field upgrades without powering down equipment. With LC duplex connectivity and LX wavelength optimized for single‑mode fiber, the module provides stable optical transmission over extended distances. Supporting 1250 Mbit/s throughput, it is suitable for common Ethernet and fiber link applications while maintaining compatibility with a wide range of networking devices that accept SFP modules.

Suitable for

• Point-to-point fiber links between switches and routers
• Extending network segments across single‑mode fiber
• Replacing or upgrading compatible SFP modules in enterprise or access networks
• Integration with media converters and fiber patch panels

Key specifications

• Form factor: SFP (small form‑factor pluggable)
• Interface: LC duplex optical connector
• Wavelength type: LX (long wavelength for single‑mode fiber)
• Data rate: 1250 Mbit/s
• Fiber type: single‑mode fiber
• Hot‑swappable: yes

How to use

Insert the transceiver into an available SFP port of a switch, router or media converter until it clicks into place. Connect LC‑terminated single‑mode fiber patch cables to the module ensuring correct transmit/receive orientation. After physical installation, verify link status and configure the device port as required by your network settings. If necessary, consult the network equipment documentation for any vendor-specific SFP compatibility or configuration steps.

Usage recommendations

Use single‑mode fiber with appropriate LC patch cords and avoid bending the fiber beyond recommended radii. Verify compatibility with the host device and monitor optical power and link stability after installation. Store unused modules in anti‑static packaging and handle the optical interface with care, keeping dust caps on when not connected.
