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

CBO SFP-1G-MMF-2KM-LE-BO is a Small Form-factor Pluggable (SFP) multimode fiber transceiver designed for 1.25 Gbit/s links with a maximum reach of 2000 meters. The module supports standard Gigabit Ethernet and common fiber-based interconnects, providing a hot-pluggable interface for easy installation and replacement in switches, routers and media converters. It is intended for reliable short-to-medium distance optical connections in enterprise and carrier-access environments.

Advantages

The module offers a standardized SFP form factor for broad compatibility with network equipment that accepts SFP transceivers. With support for 1.25 Gbit/s data rate and multimode fiber operation, it enables cost-effective fiber links over distances up to 2 km without requiring active configuration. The hot-pluggable design reduces downtime during upgrades or replacements, while the compact transceiver lowers space requirements in chassis-based systems.

Suitable for

• Gigabit Ethernet uplinks between switches in campus or building networks
• Fiber interconnects to media converters and access devices
• Short-to-medium distance links in data centers and wiring closets
• Redundant or spare transceiver inventory for service providers and IT teams

Key specifications

• Interface: Small Form-factor Pluggable (SFP)
• Data rate: 1.25 Gbit/s
• Fiber type: Multimode fiber
• Maximum reach: up to 2000 meters (multimode)
• Connector: duplex optical connector (compatible with common multimode connectors)

How to use

Insert the SFP transceiver into an empty SFP slot on a compatible switch, router or media converter while the host device is powered on or off according to the equipment manual. Connect multimode fiber patch cables to the module's optical connector, ensuring correct transmit/receive orientation and secure connections. Verify link status and optical parameters through the host device's management interface where available. Replace or reinsert the transceiver as needed for maintenance or upgrades.

Recommendations

Use multimode fiber with appropriate modal bandwidth for 1.25 Gbit/s operation and keep patch cables and connectors clean to maintain optical performance. Match transmitter and receiver types and verify link distance and attenuation budgets for reliable connectivity.
