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

CBO SFP-1G-LX-20KM is a single-mode fiber optic SFP transceiver that supports a 1 Gbps data rate and a transmission distance of up to 20 km. The module is designed for use in network switches, routers and other devices with SFP ports, offering a compact hot-pluggable interface for long-reach uplinks and point-to-point fiber connections. It implements standard LC connectors and is suitable for single-mode optical links in campus, ISP and enterprise environments where stable long-distance connectivity is required.

Advantages

The transceiver provides a standardized 1 Gbps interface with low power consumption and a small SFP form factor compatible with a wide range of network equipment. Its single-mode optics enable reliable transmission up to 20 km, reducing the need for intermediate repeater equipment. Hot-pluggable design allows installation and replacement without powering down the host device, simplifying maintenance and minimizing downtime.

Suitable for

• Long-distance uplinks between switches and routers up to 20 km
• Campus backbone and building-to-building interconnections
• ISP access and aggregation links
• Enterprise WAN links and data center connectivity

Key specifications

• Data rate: 1 Gbps (Gigabit Ethernet)
• Fiber type: Single-mode fiber (SMF)
• Maximum reach: Up to 20 km
• Connector type: LC duplex
• Form factor: SFP (Small Form-factor Pluggable)
• Wavelength: Typical 1310 nm class for LX optics
• Hot-pluggable: Yes
• Power consumption: Low (typical for SFP transceivers)

How to use

Insert the SFP transceiver into an SFP port on a compatible switch or router until it locks into place. Connect a single-mode duplex LC patch cable between the transceiver and the remote fiber device, observing correct transmit/receive orientation. Verify link status using the host device interface or LEDs. If necessary, configure the host port for 1 Gbps operation and appropriate duplex settings. To remove the module, disengage any retention mechanism and pull the transceiver straight out while the host device remains powered as supported by the hot-pluggable design.

Recommendations

Use single-mode LC patch cables of appropriate quality and ensure fiber connectors are clean before mating. Match the transceiver wavelength and reach to the link budget and fiber plant characteristics. Check compatibility with the host device and, where applicable, consult vendor recommendations for supported third-party SFP modules.
