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

The BlueOptics SFP transceiver CBO SFP-1G-LX-20KM is a compact optical module that delivers 1 Gbps data transmission over single‑mode fiber up to 20 km. Designed for insertion into standard SFP slots, this hot‑swappable transceiver enables straightforward extension of Ethernet links and interconnection between switches, routers and optical equipment. Its small form factor and compatibility with common networking devices make it suitable for enterprise networks and telecom access layers where stable long‑distance fiber links are required.

Advantages

This single‑mode SFP transceiver provides reliable 1 Gbps connectivity with a maximum reach of 20 km, reducing the need for additional intermediate devices. The hot‑swappable design allows maintenance and upgrades without powering down the host device, minimizing downtime. Compatibility with standard SFP interfaces ensures broad interoperability across switches, routers and optical equipment that support SFP modules. The module’s compact size and low power consumption simplify integration into rack and field installations.

Suitable for

• Extending Ethernet links between buildings or data closets up to 20 km over single‑mode fiber
• Interconnecting aggregation switches and routers in enterprise or ISP networks
• Replacing or upgrading existing SFP ports in network equipment for longer reach
• Telecom access and metro edge links requiring 1 Gbps optical connectivity

Key specifications

• Data rate: 1 Gbps (Gigabit Ethernet)
• Fiber type: single‑mode fiber (SMF)
• Maximum link length: up to 20 km
• Connector type: LC duplex
• Form factor: SFP (small form‑factor pluggable), hot‑swappable
• Wavelength: 1310 nm (typical for LX optics)
• Power consumption: low power class suitable for SFP hosts

How to use

Insert the transceiver into an empty SFP slot on a compatible switch, router or optical device until it seats firmly; do not force the module. Connect the single‑mode fiber terminated with LC duplex connectors, observing correct transmit/receive orientation. After insertion and fiber connection, confirm link status through the host device’s interface or LED indicators. For safe removal, follow the device’s hot‑swap procedure to avoid data interruption; pull the module straight out using the release tab or handle provided.

Recommendations

For reliable performance, use single‑mode fiber of appropriate specification and maintain clean LC connector endfaces. Verify that the host device supports 1 Gbps SFP modules and configure interface settings as needed. Avoid exceeding the specified link length of 20 km and protect fiber runs from excessive bending and physical stress.
