SFP-transceiver CBO SFP-1G-LX-20KM singlemode 1 Gbit/s 20 km

CBO SFP-1G-LX-20KM Single‑mode 1Gbps 20 km is a fiber optic SFP transceiver module designed for single‑mode links. It supports a 1 Gbps data rate and a maximum transmission distance of up to 20 kilometres over single‑mode fiber. The module is compatible with common SFP ports on switches, routers and media converters and features a compact, hot‑pluggable form factor for straightforward installation and replacement without powering down network equipment.

Advantages

The module offers reliable single‑mode connectivity for long‑distance uplinks and backbone segments, combining a stable 1 Gbps throughput with low power consumption. Its hot‑swappable design simplifies maintenance and reduces downtime when upgrading or replacing transceivers. The compact SFP form factor maximises compatibility with a wide range of network devices and allows efficient use of port density in rack-mounted equipment.

Suitable for

• Long‑distance uplinks between switches and routers in campus or enterprise networks
• Fiber backbone links connecting data closets or equipment rooms up to 20 km apart
• Media converters and edge devices requiring single‑mode 1 Gbps optical ports
• Network expansion or replacement where hot‑swappable modules are needed

Key specifications

• Form factor: SFP (small form‑factor pluggable)
• Data rate: 1 Gbps
• Fiber type: single‑mode
• Maximum reach: up to 20 km (dependent on fiber and link conditions)
• Connector type: LC duplex
• Wavelength: typical long‑reach wavelength for single‑mode links (longitudinal single mode)
• Power consumption: low (typical for small‑form transceivers)
• Hot‑pluggable: yes

How to use

Install the SFP module into an available SFP port on the target switch, router or media converter until it seats securely, observing standard ESD precautions. Connect single‑mode fiber with LC duplex connectors, ensuring correct TX/RX alignment. After insertion, the host device should recognise the module automatically; configure link settings on the device if necessary. To remove the module, disable the port if required by your equipment, then pull the module out using the module latch.

Recommendations

Use single‑mode fiber with appropriate attenuation and connector cleanliness to achieve reliable performance across distances up to 20 km. Verify compatibility with your network equipment and firmware; keep spare modules on hand for rapid replacement to minimise downtime. Follow ESD handling guidelines and avoid bending fiber below recommended radii to maintain signal integrity.
