SFP Fiber Optic Transceiver CBO SFP-1G-LX-20KM — 1 Gbps, single-mode, 20 km

The CBO SFP-1G-LX-20KM is a single-mode SFP fiber optic transceiver that supports a 1 Gbps data rate and a link reach of up to 20 km. It conforms to the standard SFP form factor and is intended for installation in switches, routers and media converters to enable long-distance single-mode Ethernet connections. The module offers a compact, hot-pluggable solution for backbone links, campus distribution and ISP aggregation where 1 Gbps long-reach connectivity is required.

Advantages

This transceiver provides a reliable 1 Gbps single-mode optical interface with a nominal 20 km reach, enabling extended-distance links without additional signal regeneration. The SFP form factor ensures wide compatibility with equipment that accepts standard SFP modules, and the hot-pluggable design allows installation or replacement without powering down the host device. The module supports common optical networking environments and helps simplify upgrades from short-reach copper or multimode solutions to single-mode long-reach fiber.

Suitable for

• Backbone fiber links between switches in campus or enterprise networks
• Long-distance uplinks for access switches and routers
• Aggregation links for ISPs and service providers
• Media converters and optical extension of Ethernet over fiber

Key specifications

• Data rate: 1 Gbps (gigabit Ethernet)
• Fiber type: single-mode
• Maximum reach: up to 20 km over single-mode fiber
• Form factor: standard SFP (small form-factor pluggable)
• Interface: optical LC connector
• Operating mode: simplex fiber, transmit and receive on separate fibers
• Hot-pluggable for in-service replacement

How to use

Insert the SFP module into an empty SFP slot on a compatible switch, router or media converter until it clicks into place. Connect single-mode fiber patch cables with LC connectors to the module's transmit and receive ports, observing correct polarity. Verify link status in the host device's interface management to confirm the 1 Gbps optical link is active. For safe removal, use the host device's recommended procedure or release latch before pulling the module out to avoid hardware damage.

Recommendations

Use single-mode fiber with appropriate attenuation and connector cleanliness to achieve the rated 20 km reach. Confirm compatibility with the host device's supported SFP modules and check link diagnostics after installation. Protect fiber routes from excessive bending and mechanical stress to maintain signal quality.
