Fiber Optic Transceiver CBO GMLC550-SX 550 m, 850 nm

CBO GMLC550-SX 550 m, 850 nm is a fiber optic transceiver designed for short-range multimode links up to 550 metres at an 850 nm wavelength. The module provides optical transmission for compatible networking equipment, enabling data connectivity over multimode fiber in LAN and campus environments. It is intended to deliver reliable signal transfer and straightforward integration with switches, routers and media converters that accept compatible SFP-style transceivers.

Advantages

The transceiver supports short-range multimode fibre connections with a maximum reach of 550 m at 850 nm, offering a balance between distance and cost for intra-campus and building-to-building links. It is compatible with standard SFP ports and enables hot-swappable installation without powering down the host device. The compact form factor and standardized optical interface simplify replacement and maintenance while providing stable optical performance suitable for typical network traffic.

Suitable for

• LAN backbone links within buildings or across campus sites
• Interconnection of switches and routers in data closets and wiring rooms
• Media converters bridging copper and multimode fiber segments
• Temporary or permanent short-range fiber deployments requiring 850 nm optics

Key specifications

• Transmission type: multimode fiber optical transceiver
• Maximum link distance: up to 550 metres
• Operating wavelength: 850 nm
• Form factor: SFP-compatible module
• Interface: duplex multimode fiber (LC connector typical)

How to use

Insert the transceiver into a compatible SFP port on the network device until it clicks into place, observing ESD precautions during handling. Connect multimode fiber cables with matching LC duplex connectors and ensure correct transmit/receive pairing. After physical installation, verify that the host device recognises the module and configure link settings as required by the network equipment. Monitor link status LEDs and network management tools to confirm stable connectivity.

Recommendations

Use multimode fibre of appropriate grade (OM1/OM2/OM3/OM4 as supported by your network design) and maintain proper cleaning of LC connectors to minimise attenuation. Keep the transceiver within the host device's supported temperature range and follow manufacturer guidelines for ESD protection and insertion/removal to ensure reliable long-term operation.
