SFP transceiver CBO SFP-1G-LX-20KM-MV-BO 1.25 Gbps LC single‑mode 20 km

CBO SFP-1G-LX-20KM-MV-BO is a single‑mode SFP optical transceiver module supporting a 1.25 Gbps line rate and designed for LC fiber connections up to 20 km. The module fits standard SFP slots in network switches, routers and media converters and enables long‑distance Ethernet or fibre channel links over single‑mode fiber. It supports the common 1250 Mbit/s data rate and complies with typical SFP form factor electrical and optical interfaces for straightforward integration into existing infrastructure.

Advantages

This SFP transceiver provides a compact, hot‑pluggable solution for extending network reach without replacing existing hardware. It offers compatibility with devices featuring SFP ports and uses an LC connector for narrow‑diameter single‑mode fiber, combining low power consumption with stable optical performance over links up to 20 km. The module’s standardized form factor simplifies inventory and deployment across enterprise and telecom networks.

Suitable for

• Extending Ethernet connections between buildings or sites up to 20 km over single‑mode fiber
• Connecting switches, routers and media converters with SFP ports
• Fibre Channel or SAN uplinks requiring 1.25 Gbps transceivers
• Telecom and enterprise backbone links where LC single‑mode connectors are used

Key specifications

• Nominal data rate: 1.25 Gbps (1250 Mbit/s)
• Fiber type: single‑mode fiber
• Maximum reach: up to 20 km (depending on fiber quality and link budget)
• Connector type: LC duplex
• Form factor: SFP (small form‑factor pluggable), hot‑pluggable
• Optical interface: long‑reach (LX) single‑mode

How to use

Insert the transceiver into an available SFP port on your switch, router or media converter until it latches. Connect a duplex LC single‑mode fiber patch cable between transceivers at both ends of the link, ensuring correct transmit/receive orientation. Power on the network devices and verify link status through device LEDs or management interfaces. Configure interface speed and duplex as required by your equipment; most systems will negotiate a 1.25 Gbps link automatically. Observe manufacturer guidance for electrostatic discharge (ESD) precautions and keep dust caps on the connector when not in use.

Recommendations

To achieve reliable performance, use high‑quality single‑mode fiber with appropriate attenuation and ensure connectors are clean before mating. Confirm optical budget compatibility with your remote transceiver and avoid sharp bends in the fiber run. For long-term stability, monitor link statistics from your networking equipment and replace the module if you observe persistent errors or signal degradation.
