SFP transceiver CBO SFP-1G-LX-20KM-HU-BO 1.25 Gbps LC single-mode 20 km

CBO SFP-1G-LX-20KM-HU-BO is a compact SFP optical transceiver module that supports a 1.25 Gbps data rate over single-mode fiber using an LC connector. Intended for installation in switches, routers and media converters, this module provides a reliable fiber link for Gigabit Ethernet and other 1.25 Gbps applications with a reach of up to 20 km. The transceiver is hot‑swappable, allowing straightforward network upgrades and maintenance without powering down the host device.

Advantages

The transceiver delivers stable single-mode performance for long-distance connections up to 20 km while maintaining low power consumption and a compact SFP form factor. Its LC duplex interface ensures compatibility with standard single-mode patch cords and passive fiber infrastructure. Hot‑swappable design minimizes downtime during installation or replacement, and the module is suitable for use in a wide range of networking equipment that accepts SFP ports.

Suitable for

• Establishing Gigabit Ethernet links between distribution and core network devices
• Connecting switches, routers and media converters over single-mode fiber
• Extending network reach for campus, metro and small data center links
• Replacing or upgrading existing SFP ports to support 1.25 Gbps fiber

Key specifications

• Data rate: 1.25 Gbps
• Fiber type: Single-mode
• Connector: LC duplex
• Maximum link distance: up to 20 km (dependent on fiber and path conditions)
• Form factor: SFP (small form-factor pluggable)
• Hot‑swappable for live insertion and removal

How to use

Insert the transceiver into an available SFP slot on a compatible switch, router or media converter until it clicks into place. Connect an LC single-mode patch cable between this transceiver and the remote device's corresponding LC port. Verify link activity and proper operation via the host device's LED indicators or management interface. When replacing or removing the module, follow the host equipment's procedures for safe hot‑swap operation to avoid disruption of other ports.

Recommendations

Choose single-mode fiber with appropriate attenuation and an LC duplex connector to achieve the specified 20 km range. Confirm the host device supports 1.25 Gbps SFP optical modules and check fiber polarity before insertion. For optimal performance, follow industry-standard fiber cleaning and handling practices and verify link parameters using the network management tools available on your equipment.
