SFP module CBO SFP-1G-LX-20KM-CO-BO 1G single-mode 20 km

CBO SFP-1G-LX-20KM-CO-BO is a compact SFP transceiver module that supports 1 Gbps data transmission over single-mode fiber for link lengths up to 20 km. Designed for installation in network equipment with standard SFP interfaces, this module provides a hot-pluggable optical interface for uplinks and point-to-point connections. It is suitable for integration into switches, routers and media converters where a reliable single-mode fiber connection is needed.

Advantages

The module offers a standard SFP form factor with hot-pluggable capability, enabling maintenance or upgrades without powering down equipment. Its single-mode design supports longer reach compared with multimode alternatives, while the 1 Gbps data rate fits a wide range of access and distribution network applications. The small footprint and compatibility with common SFP ports make deployment straightforward in rack, compact and modular devices.

Suitable for

• Single-mode fiber uplinks between switches and routers
• Point-to-point fiber links up to 20 km
• Connecting media converters to optical network segments
• Replacing or expanding SFP ports in telecom and enterprise gear

Key specifications

• Data rate: 1 Gbps (Gigabit Ethernet)
• Fiber type: single-mode fiber
• Maximum link distance: up to 20 km
• Form factor: SFP (small form-factor pluggable)
• Connector type: LC duplex
• Transmission medium: optical
• Hot-pluggable: yes

How to use

Insert the SFP module into an empty SFP slot on a compatible switch, router or media converter until it clicks into place. Connect single-mode fiber cables with LC duplex connectors to the module, observing correct transmit/receive orientation. After insertion, verify link status and configure interface settings on the host device if required for speed, duplex or VLAN parameters. For removal, power down the port if recommended by the equipment vendor and disengage the module using the release mechanism before pulling it out.

Recommendations

Use quality single-mode fiber and LC duplex connectors to achieve reliable performance over the specified 20 km range. Verify optical budgets and connector cleanliness prior to installation. Match transceiver wavelength and fiber type with the remote device to ensure compatibility. Store unused modules in anti-static packaging and avoid touching optical interfaces.
