SFP-transceiver CBO SFP-1G-LX-20KM 1G singlemode LC 20 km

The CBO SFP-1G-LX-20KM is a 1 Gbps SFP optical transceiver designed for single-mode fiber with an LC connector and a maximum reach of 20 km. It supports standard SFP form factor and hot-pluggable installation, enabling straightforward upgrades of switches, routers and media converters to gigabit fiber links. The module is suitable for establishing point-to-point fiber connections where single-mode transmission and extended reach are required.

Advantages

This transceiver offers a compact SFP form factor compatible with a wide range of network equipment that accepts SFP modules. Hot-pluggable installation allows replacement or addition without powering down devices, reducing maintenance time. Single-mode operation with LC connector and a 20 km reach provides reliable long-distance connectivity for backbone links and inter-building connections. The module supports gigabit Ethernet speeds, ensuring high-bandwidth performance for standard network and storage applications.

Suitable for

• Gigabit Ethernet links between switches and routers
• Fiber connections to media converters and network appliances
• Inter-building or campus links up to 20 km
• Short-range metro and access network segments using single-mode fiber

Key specifications

• Data rate: 1 Gbps
• Fiber type: single-mode
• Connector type: LC duplex
• Maximum reach: up to 20 km (dependent on fiber and link conditions)
• Form factor: SFP (small form-factor pluggable)
• Installation: hot-pluggable

How to use

Insert the SFP transceiver into an empty SFP slot on a compatible switch, router or media converter until it clicks into place. Connect single-mode LC duplex fiber patch cables between devices, observing correct transmit/receive orientation. Verify link status through device LEDs or management interface and confirm negotiated speed of 1 Gbps. For safe removal, follow the host device’s procedure to disable the port if required, then gently pull the module from the slot.

Recommendations

Use single-mode fiber with appropriate loss budget and clean LC connectors to achieve the specified 20 km reach. Check host device compatibility with SFP modules and ensure proper handling to avoid electrostatic discharge. For critical links, test end-to-end optical power levels and use certified fiber patch cords.
