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

BlueOptics Fiber Optic SFP Transceiver CBO SFP-1G-LH is a single-mode SFP module that delivers 1.25 Gbps data throughput using a 1310 nm wavelength for long-reach fibre links. The module is intended for installation in hot-pluggable SFP slots of switches, routers and media converters and provides a duplex LC optical interface. It supports point-to-point connections over single-mode cable and is suitable for extending network segments where distances of up to several kilometres are required.

Advantages

The transceiver provides a standardized SFP form factor with hot-plug capability for quick installation and replacement without powering down equipment. Its 1310 nm single-mode design enables lower attenuation over longer distances compared with multimode optics, while the 1.25 Gbps data rate supports typical gigabit Ethernet and fiber link applications. The duplex LC connector ensures compatibility with common single-mode patch cables and the module is suitable for use in a wide range of network devices that accept SFP optics.

Suitable for

• Long-reach point-to-point fibre connections between buildings or floors
• Gigabit uplinks for switches and routers in enterprise networks
• Media converters linking copper and single-mode fibre segments
• Telecom and ISP access links requiring single-mode fibre at 1310 nm

Key specifications

• Data rate: 1.25 Gbps (1 Gigabit)
• Optical wavelength: 1310 nm
• Fibre type: Single-mode
• Connector type: Duplex LC
• Form factor: Small Form-factor Pluggable (SFP)
• Reach: Long-reach links (typical multi-kilometre applications)
• Hot-pluggable: Yes

How to use

Install the transceiver into an empty SFP slot on a compatible switch, router or media converter while the device is powered on if hot-plugging is supported. Connect single-mode duplex LC patch cables to the module, observing correct transmit/receive orientation. Configure the network device for the appropriate link speed and verify link status through device indicators or management interfaces. When removing the module, power down the port if required by the host device, or follow safe hot-swap procedures to avoid link disruption.

Recommendations

Use single-mode LC patch cords with proper bend radius and cleanliness; inspect and clean fibre endfaces before connection to prevent signal loss. Match transceiver optical specifications with the remote device to ensure compatible link parameters. For long-distance installations, plan for appropriate splicing and attenuation budgeting to maintain reliable 1.25 Gbps links.
