SFP transceiver CBO SFP-1G-MMF-2KM-GM-BO 1.25 Gbps multimode fiber, up to 2000 m

The SFP transceiver CBO SFP-1G-MMF-2KM-GM-BO is a compact fiber-optic module that delivers a 1.25 Gbps data rate over multimode fiber for distances up to 2000 m. Designed for insertion into standard SFP ports on switches, routers and media converters, this BlueOptics transceiver supports reliable short- to mid-range optical links for network extension, uplinks and trunking in enterprise and carrier environments.

Advantages

This SFP transceiver provides a standardized form factor and hot-pluggable operation, enabling easy deployment and replacement without powering down equipment. The module offers stable 1.25 Gbps performance over multimode fiber and a transmission range up to 2000 meters, making it suitable for campus, data center interconnects and building-to-building links. Its compatibility with common SFP ports ensures broad interoperability with network equipment from multiple vendors.

Suitable for

• Extension of LAN links over multimode fiber within campuses and buildings
• Server-to-switch or switch-to-switch uplinks in data center racks
• Media converter or switch uplinks where SFP form factor is required
• Telecom access links and metropolitan networks with mid-range fiber spans

Key specifications

• Data rate: 1.25 Gbps
• Fiber type: multimode fiber (MMF)
• Maximum transmission distance: up to 2000 m
• Connector / interface: SFP form factor for 1.25 G optical ports
• Application: short- to mid-range fiber optical links, uplinks and trunking

How to use

Insert the transceiver into an empty SFP slot on a compatible switch, router or media converter until it clicks into place. Connect a multimode fiber patch cable with the appropriate connectors between this module and the remote transceiver. Ensure both ends use matching fiber type and optical parameters. After insertion, verify link status and speed on the network device and monitor for optical signal integrity. To remove, disengage any retention mechanism and pull the module straight out.

Usage recommendations

Use high-quality multimode fiber cables and maintain proper connector cleanliness to preserve link performance. Confirm that the connected ports on both ends are configured for 1.25 Gbps operation and that distance and fiber type match the module’s specifications. Store unused modules in protective anti-static packaging and avoid exposure to dust and direct sunlight.
