SFP transceiver CBO SFP-1G-MMF-2KM-AO-BO 1.25 Gbit/s multimode 2000 m

CBO SFP-1G-MMF-2KM-AO-BO is an SFP optical transceiver that supports a 1.25 Gbit/s data rate over multimode fiber for distances up to 2000 m. Intended for use in network switches, routers and fiber equipment with SFP ports, this module provides an interoperable interface for short- to medium-range fiber links. Its form factor and electrical/optical characteristics make it suitable for uplinks, access links and campus or enterprise fiber extensions where multimode cabling is already deployed.

Advantages

The transceiver offers standardized SFP form factor compatibility and stable 1.25 Gbit/s performance over multimode fiber, enabling predictable link behavior. Compact size and hot-pluggable design simplify installation and replacement without powering down equipment. Optical link support up to 2000 m on appropriate multimode fiber allows flexible deployment across building-to-building or campus scenarios. The module is designed for reliable physical connectivity and straightforward integration into existing fiber networks.

Suitable for

• Uplinks between access switches and distribution switches in enterprise networks
• Access links connecting network closets and server rooms within a campus
• Fiber extensions and retrofits where multimode cabling is installed
• Small and medium business networks requiring 1 Gbit/s fiber links

Key specifications

• Data rate: 1.25 Gbit/s
• Fiber type: multimode fiber (MMF)
• Maximum reach: up to 2000 m on suitable multimode fiber
• Form factor: SFP (small form-factor pluggable)
• Interface: optical duplex
• Hot-pluggable design for in-service installation

How to use

Insert the module into an available SFP port on a compatible switch or fiber device until it latches. Connect multimode fiber optic patch cords to the transceiver’s duplex optical interface, observing correct transmitter/receiver orientation. After connection, verify link status via the device’s management interface and check for expected link speed and signal diagnostics. For removal, power down the port if required by the host device or follow hot-swap procedures provided by the equipment vendor, then gently pull the module from the SFP cage.

Recommendations

Use appropriate multimode fiber types and quality patch cords rated for the intended distances to achieve the specified 2000 m reach. Observe ESD precautions during handling, avoid bending fibers beyond their minimum bend radius, and ensure connectors are clean to maintain optical performance. Consult the host device documentation for supported transceiver compatibility and configuration steps.
