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

The CBO SFP-1G-LX-20KM is a 1 Gigabit SFP optical transceiver engineered for single-mode fiber links up to 20 km. Designed as a compact, hot-pluggable module, it is compatible with network switches, routers and media converters that accept standard SFP interfaces. The transceiver supports 1G Ethernet connectivity for long-distance uplinks, campus backbone segments and fiber-to-equipment connections, providing a straightforward way to extend fiber links without requiring major changes to existing hardware.

Advantages

This single-mode SFP transceiver delivers reliable 1G performance over distances up to 20 km while occupying a small form factor and enabling hot-swap installation. Its adherence to common SFP electrical and optical interfaces facilitates interoperability with a wide range of networking equipment. The compact design reduces space requirements in chassis or switch ports and simplifies network upgrades or reconfigurations without powering down connected devices.

Suitable for

• Long-distance uplinks between switches or routers
• Campus backbone fiber connections
• Fiber-to-equipment links for servers and storage
• Media converters and small-form-factor network appliances

Key specifications

• Data rate: 1 Gigabit per second (1G)
• Fiber type: single-mode fiber
• Maximum link distance: up to 20 km
• Form factor: SFP (Small Form-factor Pluggable)
• Connector type: LC duplex
• Optical wavelength: typical 1310 nm for long-reach single-mode links
• Hot-pluggable design for live installation and replacement

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 fiber cables with LC connectors to the transceiver ports, observing proper transmit/receive orientation. The module is hot-pluggable, so it can be installed or removed while the host device remains powered in most environments; consult the host device documentation for any device-specific procedures. After installation, verify link status and speed through the host device management interface or status LEDs.

Recommendations

Use single-mode fiber cables and LC connectors rated for the intended distance and ensure clean connector endfaces to maintain signal integrity. Verify compatibility with the host device's SFP port and firmware; when deploying in critical links, test the module in the target environment to confirm expected performance. Avoid exposing the transceiver to extreme temperatures or excessive mechanical stress during insertion and removal.
