SFP transceiver CBO SFP-1G-EX-SS-BO 1,25 Gbit/s 1250 Mbit/s singlemode 40 000 m

CBO SFP-1G-EX-SS-BO is a single-mode SFP transceiver supporting a 1.25 Gbps (1250 Mbit/s) data rate and a maximum link distance of up to 40,000 m. Designed for optical network uplinks and long-distance fiber connections, this module fits standard SFP ports and provides a compact solution for establishing reliable gigabit connectivity between switches, routers and media converters in telecom and industrial environments.

Advantages

This SFP transceiver offers extended reach for long-haul fiber links while maintaining compatibility with standard SFP interfaces. Its single-mode design allows for clear signal transmission over tens of kilometers, and the 1.25 Gbps data rate meets common gigabit Ethernet and fiber channel uplink requirements. The module's compact SFP form factor simplifies integration into existing network equipment without requiring special adapters.

Suitable for

• Long-distance fiber uplinks between network switches and routers
• Telecom backbone and metropolitan area network links
• Industrial network connections requiring extended reach
• Media converters and optical interface cards

Key specifications

• Form factor: SFP (small form-factor pluggable)
• Data rate: 1.25 Gbps (1250 Mbit/s)
• Optical mode: Single-mode
• Maximum link distance: up to 40,000 m (40 km)
• Typical applications: Gigabit uplinks, optical network interconnects

How to use

Insert the SFP transceiver into a compatible SFP port on your switch, router or media converter until it latches. Connect a single-mode fiber patch cable to the transceiver's optical interface, ensuring correct connector type and polarity. After physical installation, verify link status on the network device and configure relevant interface settings (speed, duplex, or optical diagnostics) as required by your equipment. Follow manufacturer guidance for hot-plugging if supported by the host device.

Recommendations

Use single-mode fiber of appropriate quality and connectors rated for long-distance links, and verify end-to-end attenuation to ensure signal margin. Avoid bending or stressing the fiber near connectors. Check compatibility notes from your network equipment vendor regarding supported SFP modules and platform firmware before deployment.
