SFP Transceiver CBO SFP-1G-LH 1G 1310nm single-mode 10km

SFP Transceiver CBO SFP-1G-LH is a 1 Gbps fiber optic module designed for use with single-mode fiber at a wavelength of 1310 nm. The transceiver supports link distances up to approximately 10 km and fits standard SFP slots in switches, routers and media converters. It provides a straightforward solution for establishing point-to-point uplinks and extending connections in metro and access network segments while maintaining low latency and stable throughput.

Advantages

The module offers compatibility with equipment that accepts SFP form factor transceivers and delivers 1 Gbps data rate over single-mode fiber, enabling long-reach connections without the need for wavelength conversion. Operating at 1310 nm, it balances range and dispersion characteristics suitable for short to medium long-haul links. Its compact SFP size allows hot-pluggable installation and easy replacement or upgrade of optical interfaces.

Suitable for

• Uplink connections between switches and routers in campus or enterprise networks
• Access network links for ISPs and metro aggregation
• Fiber backbone segments requiring up to 10 km reach
• Media converters and optical line modules in network equipment

Key specifications

• Data rate: 1 Gbps (SFP standard)
• Wavelength: 1310 nm
• Fiber type: single-mode fiber (SMF)
• Maximum reach: up to approximately 10 km (depends on fiber quality and link margin)
• Form factor: SFP (hot-pluggable)
• Connector: LC duplex
• Transmission: full-duplex optical link

How to use

Insert the SFP transceiver into an available SFP port on a compatible switch, router or media converter until it clicks into place. Connect single-mode fiber with LC duplex connectors between devices, ensuring correct transmit/receive orientation. Verify link status on the host device and configure interface settings (speed/duplex/autonegotiation) if required by the network equipment. For safe removal, use the device’s port shutdown or follow hot-swap procedures to avoid link disruption.

Recommendations

Confirm compatibility with the host device and optical link budget before deployment. Use quality single-mode fiber and keep connectors clean to maintain optimal signal integrity. Avoid bending the fiber beyond recommended radii and ensure proper labeling of fiber runs for maintenance. For distances approaching the module’s maximum reach, verify loss and dispersion parameters to ensure reliable operation.
