## Summary description

CBO SFP-1G-LX-20KM is an SFP fiber optic transceiver for single-mode links with a 20 km reach. It supports 1.25 Gbps data rate and installs in standard SFP ports to extend network connections over long distances. Use it to connect switches, routers or media converters in campus, ISP or enterprise links where reliable single-mode fiber transmission is required.

## Long description

CBO SFP-1G-LX-20KM is a single-mode SFP fiber transceiver designed for fiber links up to 20 km. The module provides a 1.25 Gbps data rate and fits into standard SFP ports to extend network connectivity between switches, routers and media converters. It is intended for point-to-point single-mode fiber connections where stable optical transmission over medium distances is required.
Advantages
The transceiver supports a 1.25 Gbps line rate and single-mode operation, enabling long-reach connections without additional conversion equipment. Its SFP form factor ensures compatibility with a wide range of network devices that accept hot-pluggable SFP modules. The module's design targets low power consumption and reliable optical performance to maintain link integrity over distances up to 20 km.
Suitable for
 Connecting switches across buildings or campus sites over single-mode fiber
 Extending links between routers or media converters in enterprise and ISP networks
 Replacing or upgrading short-haul fiber transceivers to achieve longer reach
 Use in fiber backbone segments that require 1 Gbps connectivity over up to 20 km
Key specifications
 Form factor: SFP (hot-pluggable)
 Data rate: 1.25 Gbps
 Fiber type: single-mode
 Maximum reach: up to 20 km over single-mode fiber
 Wavelength: typical long‑reach optical wavelength for single-mode links
 Interface: LC duplex optical connector
 Power characteristics: low-power SFP class
How to use
Insert the SFP transceiver into a compatible SFP port on a switch, router or media converter while the device is powered on or off as supported by the host. Connect the LC duplex single-mode fiber cable to the module's optical ports, ensuring correct transmit/receive orientation. Verify link status through the host device LEDs or management interface and confirm the negotiated speed is 1 Gbps. If necessary, consult the host equipment documentation for any specific compatibility or configuration settings required for third-party SFP modules.
Usage recommendations
Use certified single-mode duplex fiber with appropriate attenuation and follow proper fiber handling practices to avoid contamination. For installations approaching 20 km, measure link loss and allow margin for splice and connector loss. Ensure that the host device supports SFP modules with the stated optical parameters for stable operation.
