Fiber optic SFP transceiver CBO SFP-100-SM40 100 Mbps single-mode 40 km

BlueOptics Fiber optic SFP transceiver CBO SFP-100-SM40 provides a compact single-slot solution for 100 Mbps Ethernet transmission over single-mode fiber. Designed for insertion into SFP ports of switches, routers and media converters, this transceiver supports optical links up to 40 km, enabling stable long-distance connectivity with low latency. The module is suitable for telecoms, ISP backbones, enterprise networks and CCTV systems that require a reliable fiber uplink.

Advantages

The transceiver offers a standardized SFP form factor that ensures compatibility with a wide range of network equipment featuring SFP ports. It delivers a fixed 100 Mbps data rate over single-mode fiber for predictable throughput and low jitter. With support for distances up to 40 km, the module reduces the need for intermediate repeaters or active equipment on long links, simplifying network design and lowering infrastructure costs.

Suitable for

• Long-distance Ethernet links between buildings or sites
• Fiber uplinks for switches and routers in enterprise networks
• Backbone connections for ISPs and telecom providers
• CCTV and video surveillance networks requiring optical transmission

Key specifications

• Data rate: 100 Mbps
• Fiber type: single-mode
• Maximum link distance: up to 40 km
• Form factor: SFP (1.25 Gbps electrical interface compatibility)
• Transmission medium: LC connector single-mode fiber
• Operating wavelength: typical single-mode wavelength band (nm)

How to use

Insert the module into a compatible SFP port on your switch, router or media converter while the host device is powered on or off according to the equipment manual. Connect single-mode fiber with LC connectors to the module's ports, maintaining proper fiber handling and bend-radius limits to avoid signal loss. After physical installation, verify link status and network configuration on the host device and adjust interface settings if necessary to match the 100 Mbps operation.

Recommendations

To ensure reliable long-distance operation, use certified single-mode fiber of appropriate attenuation for the planned 40 km span, test the fiber link with an optical power meter or light source, and observe ESD precautions when handling the transceiver. Confirm compatibility with your host equipment and review the device manual for hot-swap guidance and interface configuration.
