## Summary description

SFP+ CBO SFP-10G-BX-U-40KM-SS-BO is a 10 Gbit/s single-mode optical transceiver with an LC interface designed for long-reach point-to-point links up to 40 km. It supports BX-U operation (upstream), enabling wavelength-division duplexing on single fiber. Suitable for switches, routers and optical equipment requiring compact hot-pluggable 10G ports, providing reliable high-speed connectivity in metro and enterprise networks.

## Long description

SFP+ CBO SFP-10G-BX-U-40KM-SS-BO is a 10 Gbit/s single-mode optical transceiver with an LC connector, designed for long-reach point-to-point links up to 40 km. The module supports BX-U operation (upstream) which enables wavelength-division duplexing on a single optical fibre, reducing fibre cabling requirements. This hot-pluggable SFP+ form factor is compatible with switches, routers and optical equipment that provide 10G SFP+ ports and is aimed at metro and enterprise network deployments that require compact, high-speed uplinks.
Advantages
The transceiver delivers 10 Gbit/s full-rate transmission over single-mode fibre to 40 km, providing a balance of reach and compactness in the SFP+ form factor. BX-U operation allows upstream wavelength multiplexing on a single fibre, enabling cost-effective duplex links without the need for separate fibres. Its LC interface and hot-pluggable design simplify installation and replacement in live systems. The module is suitable for environments where small size, power efficiency and compatibility with standard 10G ports are important.
Suitable for
 Long-reach point-to-point 10G uplinks in metro and campus networks
 Upstream links requiring wavelength-division duplexing on single fibre
 10G SFP+ ports on switches and routers in enterprise networks
 Optical add/drop and aggregation applications with space or fibre constraints
Key specifications
 Data rate: 10 Gbit/s
 Fibre type: Single-mode fibre (SMF)
 Maximum reach: Up to 40 km (single-mode)
 Connector type: LC duplex (single-fibre WDM uses LC)
 Operation mode: BX-U (upstream) for wavelength-division duplexing
 Form factor: SFP+ hot-pluggable module
How to use
Insert the SFP+ transceiver into an appropriate 10G SFP+ slot on a compatible switch, router or optical device while the device is powered according to the vendor guidelines for hot-plugging. Connect the single-mode fibre using LC connectors and ensure the remote link uses the complementary BX-D (downstream) module or matching wavelengths for proper WDM operation. Monitor link status via the host device to confirm proper negotiation and optical levels. Follow standard safety procedures for handling fibre optics and avoid touching connector endfaces.
Usage recommendations
Use clean single-mode LC patch cords and verify power budgets for 40 km reach in your specific installation. For WDM/BX links, pair upstream and downstream modules with matching wavelengths and verify compatibility with the host device to ensure stable 10G operation. Keep spare modules on hand for quick replacement in critical network paths.
