SFP module CBO SFP-1G-EX-NK-BO 1 Gbit/s 1250 Mbps single‑mode 40,000 m

CBO SFP-1G-EX-NK-BO is a small form-factor pluggable (SFP) optical transceiver module designed for single-mode fiber networks. It supports a 1 Gbit/s line rate (1250 Mbps) and provides a transmission reach of up to 40,000 meters, offering a hot-swappable interface for compatible switches and routers. The module is intended for long-distance uplinks, metro and carrier links, and fiber backbone extensions where single-mode optics are required.

Advantages

The SFP module delivers stable gigabit performance over single-mode fiber for long distances, reducing the need for intermediate regenerators. Its hot-pluggable design allows quick replacement or upgrades without powering down network equipment. Low power consumption and compact SFP form factor make it suitable for dense port configurations in switches and routers. The module conforms to common optical and electrical interface standards, enabling broad compatibility with single-mode networking gear.

Suitable for

• Long-distance Ethernet uplinks between buildings and data centers
• Metro-area fiber connections and carrier aggregation links
• Fiber backbone extensions and campus networks
• Replacement or upgrade of single-mode SFP ports in switches and routers

Key specifications

• Data rate: 1 Gbit/s (line rate 1250 Mbps)
• Fiber type: single-mode
• Maximum reach: up to 40,000 meters
• Connector type: standard SFP cage interface (hot‑swappable)
• Optical wavelength: typical single-mode transmission band (vendor-specific)
• Form factor: Small Form-Factor Pluggable (SFP)
• Power consumption: low-power SFP class

How to use

Insert the SFP module into an empty SFP slot on a compatible switch or router until it seats securely. Connect a single-mode fiber optic cable with the appropriate connector to the module. Ensure both ends of the fiber are clean and properly terminated. After insertion, the host device should detect the module and negotiate link parameters at 1 Gbit/s. Monitor link LEDs or the management interface to confirm a stable connection and proper optical levels.

Recommendations

For reliable long-distance operation, use single-mode fiber rated for long-reach deployments and verify fiber attenuation over the planned route. Clean optical connectors before connection and follow the host equipment compatibility list to ensure full interoperability. Consider using protective dust caps when the module is not connected and observe proper ESD handling when inserting or removing the transceiver.
