Transceptor SFP CBO SFP-1G-LX-20KM-CH-BO 1,25 Gbit/s LC monomodo 20 km

The CBO SFP-1G-LX-20KM-CH-BO is a compact SFP optical transceiver that supports 1.25 Gbps data rate for single‑mode fiber links with an LC connector and a reach of up to 20 km. Intended for installation in compatible SFP ports of switches, routers and media converters, this transceiver offers hot‑pluggable operation and straightforward fiber connectivity for point‑to‑point links and uplink installations.

Advantages

This SFP transceiver provides a standardized 1.25 Gbps interface suitable for 1 Gbit/s Ethernet applications over single‑mode fiber. Its LC connector and small form factor enable space-efficient use in network equipment. Hot‑pluggable design allows replacement or upgrades without powering down the host device. The product is designed to meet common optical transceiver electrical and optical characteristics for reliable long‑distance links up to 20 km.

Suitable for

• Uplink connections between switches and routers over single‑mode fiber
• Long‑distance point‑to‑point fiber links up to 20 km
• Media converters and fiber access equipment requiring SFP modules
• Network installations that use LC connector SFP ports

Key specifications

• Data rate: 1.25 Gbps (suitable for 1 Gbit/s Ethernet)
• Fiber type: single‑mode fiber
• Connector: LC duplex
• Maximum reach: up to 20 km
• Form factor: SFP (Small Form‑factor Pluggable), hot‑pluggable
• Wavelength: long‑reach (LX) class optics

How to use

Insert the SFP transceiver into a compatible SFP port on a switch, router or media converter until it seats securely. Connect the single‑mode LC duplex fiber cable to the transceiver, ensuring correct transmit/receive orientation. The module supports hot‑plugging, but follow your equipment manufacturer's guidelines for link negotiation and any required configuration such as port speed or duplex settings. Monitor link LEDs on the host device to confirm successful connection and link activity.

Recommendations

Use clean, properly terminated single‑mode fiber with LC connectors and follow standard fiber‑handling procedures. Avoid bending the fiber beyond its minimum bend radius and protect transceiver optical interfaces from dust by using dust caps when not connected. Verify compatibility with the host device's SFP port and consult device documentation for any vendor-specific settings.
