## Summary description

This CBO SFP-10G-BX-D-40KM SFP+ transceiver is a 10 Gigabit single-fiber bi-directional (bi-di) optical module designed for links up to 40 km. It fits SFP+ slots and supports duplex transmission over one fiber using wavelength-division. Typical use cases include long-reach uplinks, metro and campus networks, and point-to-point connections. Benefits include compact hot-pluggable design and compatibility with SFP+ ports for straightforward network upgrades.

## Long description

The CBO SFP-10G-BX-D-40KM is a 10G SFP+ single-fiber bi-directional (bi-di) optical transceiver designed for links up to 40 km. It supports 10 Gigabit Ethernet and fits standard SFP+ ports, enabling duplex transmission over a single optical fiber by using different transmit and receive wavelengths. The module is hot-pluggable and compact, intended for use in uplinks, point-to-point connections, metro and campus networks where fiber availability or cost favors single-fiber solutions.
Advantages
This SFP+ transceiver reduces fiber infrastructure requirements by allowing transmit and receive channels on one fiber, which saves on cabling and simplifies deployment. Its hot-pluggable SFP+ form factor enables quick upgrades or replacements without shutting down equipment. The module supports standard 10G rates and long-reach optical performance suitable for distances up to 40 km, providing predictable behavior for network planning and inventory standardization.
Suitable for
Long-reach uplink links between aggregation and core switches
Point-to-point connections across campus or metro spans
Environments with limited fiber availability where single-fiber bi-di saves cabling
Network equipment with SFP+ ports requiring 10G optical interfaces
Key specifications
Interface: SFP+ form factor, hot-pluggable
Data rate: 10 Gigabit Ethernet
Fiber type: single-mode fiber (SMF)
Operation mode: bi-directional (bi-di) single-fiber using wavelength-division
Maximum reach: up to 40 km (dependent on fiber quality and link loss)
Wavelength: separate TX and RX wavelengths for bi-di operation
Connector: LC duplex (single-fiber bi-di uses LC with appropriate breakout or patching)
How to use
Insert the SFP-10G-BX-D-40KM module into an available SFP+ slot on a compatible switch, router or media converter while the host device is powered on or off, as the module supports hot-plug operation. Connect single-mode fiber with compatible LC connectors and ensure correct polarity and wavelength pairing at each link end (one end uses the complementary bi-di module variant). Configure the host port for 10G operation if necessary and verify link status through the device management interface. Monitor optical power and errors during initial deployment to confirm link quality.
Usage recommendations
Use clean single-mode fibers and LC connectors, adhere to specified link loss budgets, and pair the module with the complementary bi-di transceiver at the remote end. Verify that the host device accepts third-party SFP+ modules or enable required compatibility settings. For reliable long-reach performance, account for connector losses, splices and fiber attenuation when planning links up to 40 km.
