SFP Fiber Optic Transceiver CBO SFP-1G-LH 1.25Gbps 1G 1310nm Single-Mode

The CBO SFP-1G-LH is a single-mode SFP fiber optic transceiver designed for 1 Gbps Ethernet links using a 1310 nm wavelength. Supporting a nominal 1.25 Gbps electrical interface, this compact hot-pluggable module is intended for insertion into SFP ports of switches, routers and media converters to establish long-reach optical connections. It is suitable for backbone, aggregation and access network segments where single-mode fiber is deployed and offers a straightforward way to extend or restore fiber Ethernet links without replacing network equipment.

Advantages

The transceiver provides reliable single-mode performance at 1310 nm with support for standard 1 G Ethernet signaling. Its hot-swappable SFP form factor allows installation or replacement without powering down host devices. The module’s compact design reduces space requirements in equipment chassis while maintaining compatibility with common SFP ports. Built for long-reach applications, it enables optical connections over extended distances compared with multimode alternatives.

Suitable for

• Long-reach Ethernet links in campus backbone and carrier access networks
• Interconnecting switches and routers in data center aggregation layers
• Media converter deployments converting copper to single-mode fiber
• Replacing faulty or incompatible SFP transceivers in existing fiber links

Key specifications

• Data rate: 1 Gbps (nominal 1.25 Gbps electrical interface)
• Optical wavelength: 1310 nm (single-mode)
• Form factor: SFP (hot-pluggable)
• Fiber type: single-mode fiber (SMF)
• Connector type: standard LC duplex interface
• Operating temperature range: industrial and commercial variants may apply—check equipment requirements

How to use

Insert the SFP module into an available SFP slot on a compatible switch, router or media converter until it seats and the latch engages. Connect the single-mode fiber patch cable to the module’s LC connector, ensuring correct transmit-to-receive orientation. Verify link status via the host device’s port LEDs or management interface and configure interface settings (speed, duplex, auto-negotiation) as required by the network. For removal, release the module latch and pull the module straight out while the host device is powered according to vendor guidance if hot-plugging.

Recommendations

Store transceivers in protective packaging when not in use and keep LC dust caps on until cables are connected. Use single-mode patch cables and proper fiber cleaning tools to maintain optical performance. Confirm compatibility with the host device’s SFP port and firmware policies before deployment to avoid link issues.
