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

CBO SFP-1G-LX-20KM is a 1G SFP optical transceiver engineered for single-mode fiber links up to 20 km. The module uses a standard LC connector and is compatible with SFP ports on switches, routers and other network equipment that accept 1G SFP modules. It enables extension of Ethernet connections over longer distances and can be used for fibre backbone links or as a replacement module in compatible devices.

Advantages

The transceiver supports 1 Gbps data rates over single-mode fiber with stable optical performance suited for access and distribution layers. Its LC interface provides a compact duplex connection and the small form-factor pluggable (SFP) housing allows hot-swap installation without powering down equipment. The module is designed for straightforward compatibility with standard SFP slots and low-power operation appropriate for rack-mounted and standalone network devices.

Suitable for

• Extending Ethernet links up to 20 km over single-mode fiber
• Interconnecting switches and routers in campus or enterprise networks
• Fibre backbone and distribution segment connections
• Replacing faulty or absent 1G SFP modules in compatible equipment

Key specifications

• Data rate: 1 Gbps
• Fiber type: single-mode
• Maximum link distance: 20 km
• Optical interface: duplex LC
• Form factor: SFP (small form-factor pluggable)
• Typical power consumption: low-power class suitable for SFP slots

How to use

Insert the SFP module into a compatible SFP port on the network device until it latches, then connect the duplex LC fiber cable following correct Tx/Rx orientation. Ensure the connected devices are configured for 1 Gbps operation and single-mode fiber on the appropriate interfaces. Monitor link LEDs and device diagnostics to verify optical signal presence and correct operation. For hot-swap replacement, remove the module using the release mechanism and insert the replacement module while observing anti-static handling procedures.

Recommendations

Use certified single-mode fiber with appropriate attenuation characteristics for links up to 20 km, keep LC connectors clean to maintain optical performance, and check device compatibility lists if exact vendor locking is a concern. Store and handle the transceiver in a static-safe environment and avoid bending fiber beyond recommended radii.
