SFP transceiver CBO SFP-1G-LX-20KM-NV-BO 1G single‑mode 20 km

The CBO SFP-1G-LX-20KM-NV-BO is a 1G SFP transceiver designed for single-mode fiber links with a reach up to 20 km. It provides a hot-pluggable interface compatible with Gigabit Ethernet and common optical networking equipment, enabling long-distance uplinks, server connections and fiber backbone extensions. The compact SFP form factor allows easy installation in switches, routers and media converters that accept standard SFP modules.

Advantages

This single-mode SFP transceiver supports a maximum link distance of 20 km, offering a balance between reach and compact footprint for enterprise and service provider networks. Its hot-pluggable design reduces downtime during maintenance or upgrades. The module is engineered for interoperability with a wide range of networking devices that accept standard SFP form factor modules, enabling flexible deployment in existing infrastructures.

Suitable for

• Long-distance Gigabit Ethernet uplinks between buildings or data closets
• Server-to-switch fiber connections in campus and data center environments
• Extending fiber backbone links within enterprise and ISP networks
• Integration with switches, routers and media converters that support SFP modules

Key specifications

• Data rate: 1 Gbit/s (Gigabit Ethernet)
• Fiber type: single-mode fiber
• Maximum optical reach: up to 20 km
• Form factor: SFP (small form-factor pluggable), hot-pluggable
• Wavelength: typical 1310 nm for long-distance single-mode links
• Connector type: LC duplex

How to use

Insert the SFP transceiver into an empty SFP port on a compatible switch, router or media converter until it clicks into place. Connect single-mode LC duplex fiber patch cables to the transceiver’s connectors, ensuring correct transmit/receive orientation. After insertion and cable connection the host device should automatically detect the module; verify link status and speed via the device management interface. To remove the transceiver, disengage any locking mechanism and pull the module straight out while observing electrostatic discharge precautions.

Recommendations

Use clean single-mode fiber and LC connectors to maintain optical performance; inspect and clean connectors before mating. Verify compatibility with the host device’s SFP port and consult device documentation for any vendor-specific settings. Operate the transceiver within specified temperature and humidity ranges and avoid exposing optical ports to direct sunlight or contamination when not in use.
