## Summary description

CBO J4858C-LEG-BO is an SFP fiber optic transceiver supporting 1250 Mbit/s data rate with LC connector for shortwave (SX) multimode links up to 550 m. Designed for insertion into compatible SFP ports, it enables reliable duplex fiber connections for switches, routers and media converters, useful for campus, data center and enterprise network links.

## Long description

CBO J4858C-LEG-BO is an SFP fiber optic transceiver designed for 1250 Mbit/s operation over multimode fiber. The module uses an LC duplex connector and shortwave (SX) optics to support reliable point-to-point duplex links up to 550 meters when installed in compatible SFP ports on switches, routers or media converters. It is intended to provide a compact hot-pluggable solution for upgrading or extending fiber segments in campus, data center and enterprise network environments.
Advantages
The transceiver supports a 1250 Mbit/s data rate and SX multimode optics, allowing straightforward replacement or expansion of fiber ports without requiring major hardware changes. Its LC duplex interface and standardized SFP form factor ensure wide compatibility with devices that accept SFP modules. The small size and hot-pluggable capability simplify installation and maintenance while minimizing downtime for live network equipment.
Suitable for
 Short-range multimode fiber links within buildings and campus grounds
 Uplinks between switches and aggregation points in data centers
 Connections between routers, media converters and network appliances
 Enterprise network segments requiring 1250 Mbit/s full-duplex fiber
Key specifications
 Interface: LC duplex connector for fiber optic cable
 Optical type: Shortwave (SX) multimode optics
 Nominal data rate: 1250 Mbit/s
 Maximum link distance: up to 550 meters on suitable multimode fiber
 Form factor: Small Form-factor Pluggable (SFP), hot-pluggable

How to use
Insert the transceiver carefully into a compatible SFP port on your network device until it latches. Connect LC duplex multimode fiber patch cords, ensuring correct transmit/receive orientation. Verify link status and data rate through the device management interface or LED indicators. For best results, use multimode fiber with appropriate bandwidth-distance characteristics and maintain proper connector cleanliness to avoid signal loss.
Usage recommendations
Use this module in environments where short-range multimode fiber is appropriate; clean connectors before mating, avoid exceeding the specified link distance, and verify compatibility with the host device's supported SFP transceiver types and optical parameters.
