SFP transceiver CBO SFP-1G-LX-20KM-IT-BO 1,25 Gbit/s singlemode LC, do 20 km

CBO SFP-1G-LX-20KM-IT-BO is a 1.25 Gbps SFP optical transceiver designed for single-mode fiber networks with an LC connector and a reach of up to 20 km. The module supports standard serial optical Ethernet links and provides a compact hot-pluggable interface for switches, routers and media converters. It is intended for use in enterprise and telecom environments where reliable 1 G fiber uplinks and long-distance point-to-point connections are required.

Advantages

The transceiver offers stable 1.25 Gbps data transmission over single-mode fiber and a maximum link distance up to 20 km, which enables long-reach connections without intermediate equipment. Its LC connector and SFP form factor ensure broad compatibility with network devices that accept small form-factor pluggable modules. The hot-pluggable design allows maintenance and upgrades without powering down network equipment, while industry-standard electrical and optical interfaces simplify integration into existing networks.

Suitable for

• 1 Gbps uplinks between switches in enterprise campus networks
• Long-distance fiber links to remote buildings or data closets up to 20 km
• Fiber connections for routers and media converters in telecom access networks
• Network redundancy and backbone links requiring single-mode LC interfaces

Key specifications

• Nominal data rate: 1.25 Gbps
• Fiber type: single-mode (SMF)
• Connector type: LC duplex
• Maximum reach: up to 20 km (depending on fiber quality and link budget)
• Wavelength: long wavelength (LX) class
• Form factor: SFP (small form-factor pluggable)
• Operation: hot-pluggable

How to use

Insert the SFP transceiver into an SFP-compatible port on a switch, router or media converter until it seats firmly. Connect a single-mode LC duplex fiber cable, matching transmit and receive pairs at both ends of the link. Verify link status via the host device LEDs or management interface and ensure the device is configured for 1 G operation if required. When removing the module, use the latch or release mechanism provided by the host port and handle the transceiver by its edges to avoid contaminating the optical interfaces.

Recommendations

Use clean LC connectors and inspect fiber endfaces before installation to maintain signal quality. Choose single-mode fiber with appropriate attenuation and dispersion characteristics for distances up to 20 km, and verify link budget in mixed-vendor setups. Store spare transceivers in protective caps and avoid touching the optical ferrules.
