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

The BlueOptics SFP Transceiver CBO SFP-1G-LX-20KM is a compact optical module designed for 1 Gbps Ethernet links over single‑mode fiber with a reach of up to 20 km. It fits standard SFP slots and implements the LX interface, enabling interoperability with a wide range of switches, routers and optical equipment. The module supports simple hot‑swap deployment and is suitable for expanding or upgrading fiber infrastructure in enterprise and telecom environments.

Advantages

This SFP transceiver offers a small form factor with low power consumption and a proven LX optical interface for long‑reach single‑mode links. Its compatibility with standard SFP ports allows for flexible integration into existing network hardware without requiring chassis modifications. The module provides reliable data transmission at 1 Gbps and supports distances up to 20 km, enabling cost‑effective extension of fiber connections between sites.

Suitable for

• Connecting switches and routers over single‑mode fiber for campus or metro links
• Extending backbone or inter‑building Ethernet links up to 20 km
• Upgrading network ports to 1 Gbps fiber connectivity in enterprise networks
• Use in telecom access, aggregation and optical distribution equipment with SFP slots

Key specifications

• Data rate: 1 Gbps (Gigabit Ethernet)
• Fiber type: single‑mode fiber
• Maximum link distance: up to 20 km (depends on fiber quality and link conditions)
• Optical interface: LX (long‑reach 1310 nm wavelength typical)
• Form factor: SFP (small form‑factor pluggable), hot‑pluggable
• Power consumption: low (typical for SFP class transceivers)

How to use

Insert the transceiver into an available SFP port on a compatible switch, router or optical device until it clicks into place. Connect single‑mode fiber patch cables to the module’s optical connector, observing correct transmit/receive orientation. Configure the connected network port as required by your device; many systems will detect the module automatically and report link status. For hot‑swap replacement, ensure network traffic is managed according to your operational procedures to avoid disruption.

Recommendations

Use quality single‑mode fiber and proper connector cleaning practices to achieve reliable links. Verify compatibility with the host device vendor’s SFP specifications when planning deployment, and test link performance after installation, especially when approaching the 20 km distance limit.
