SFP+ optical transceiver CBO SFP-10G-BX-U-40KM-SW-BO 10 Gbit/s LC single-mode 40 km

SFP+ CBO SFP-10G-BX-U-40KM-SW-BO is a 10 Gbit/s small form-factor pluggable optical transceiver engineered for single-mode fiber links up to 40 km. Designed for use in 10G Ethernet and optical networking environments, this LC-terminated module enables long-reach uplinks for switches and routers, datacenter interconnects and service provider links. The transceiver supports hot-plug installation in compatible SFP+ ports and is intended for telecommunication and enterprise network applications that require reliable 10 Gbit/s optical connectivity over single-mode fiber.

Advantages

The module delivers 10 Gbit/s transmission over single-mode fiber with LC duplex connectivity, offering a compact SFP+ form factor that conserves port space in network equipment. It supports long-reach links up to 40 km, which allows for simplified network design and reduced need for intermediate repeaters. Hot-pluggable capability helps minimize downtime during upgrades or replacements, while the standardized SFP+ interface provides broad interoperability with network switches and routers that accept SFP+ optical transceivers.

Suitable for

• 10G Ethernet uplinks between switches and routers
• Datacenter interconnects and aggregation links
• Service provider access and metro optical links
• Long-reach campus or enterprise connections over single-mode fiber

Key specifications

• Data rate: 10 Gbit/s
• Fiber type: single-mode fiber (SMF)
• Maximum reach: up to 40 km on single-mode fiber
• Connector type: LC duplex
• Form factor: SFP+
• Transmission wavelength: device-specific for bidirectional single-fiber or standard single-mode operation (check equipment compatibility)
• Hot-pluggable: yes

How to use

Insert the SFP+ optical transceiver into a compatible SFP+ port on your switch, router or media converter while the host device is powered on or off as supported. Connect LC single-mode fiber patch cords according to the device's port labeling and polarity requirements. Verify link status and speed on the host device management interface; configure the port for 10G operation if necessary. When removing the module, power down the port if recommended by the equipment manufacturer or follow hot-swap procedures supported by the host device to avoid network disruption.

Recommendations

Confirm compatibility between the transceiver and the host device before installation, including support for SFP+ optics and required firmware or vendor interoperability settings. Use quality single-mode LC patch cords and maintain proper fiber handling to preserve signal performance over long distances. For links approaching 40 km, verify end-to-end loss budget and consider optical attenuation, connector cleanliness and splicing losses.
