## Summary description

CBO SFP-10G-BX-U-40KM-IX-BO is an SFP+ optical transceiver module supporting 10 Gbit/s data rate for single-mode fiber with an LC connector and a reach of up to 40 km. The BX-U variant provides unidirectional (upstream) transmission in wavelength-division pairs. Designed for data center, metro and access networks, it enables high-speed uplinks and long-distance links between switches and routers.

## Long description

CBO SFP-10G-BX-U-40KM-IX-BO is an SFP+ optical transceiver module that supports 10 Gbit/s data transmission over single-mode fiber with an LC connector and a maximum reach of up to 40 km. The BX-U variant provides unidirectional upstream transmission as part of a wavelength-division pair, allowing the module to be paired with a complementary downstream transceiver to create a full bidirectional link over a single fiber. It is designed for use in data centers, metro and access networks where long-reach uplinks and compact form factor are required.
Advantages
This SFP+ transceiver offers a compact hot-pluggable design compatible with standard SFP+ slots and delivers 10 Gbit/s line rate while reducing fiber cabling by using wavelength-division multiplexing in BX configuration. The single-mode 40 km reach enables long-distance links without intermediate amplification, and the LC connector ensures broad compatibility with existing single-mode patch cords. The unidirectional BX-U design supports efficient allocation of upstream wavelengths, which is useful in point-to-point and ring topologies where separate transmit and receive wavelengths are required.
Suitable for
High-speed uplinks between switches and routers in enterprise and carrier networks
Long-distance links in metro and access network segments
Point-to-point fibre connections using wavelength-division pairs
Data centre uplink ports and compact networking equipment with SFP+ cages
Key specifications
Data rate: 10 Gbit/s
Fiber type: single-mode
Connector: LC duplex
Maximum reach: up to 40 km (single-mode)
Form factor: SFP+ (hot-pluggable)
Transmission direction: unidirectional upstream (BX-U, part of wavelength-division pair)
How to use
Install the transceiver by inserting it into a compatible SFP+ slot on a switch, router or media converter until it locks. Connect a single-mode LC patch cable between the transceiver and the fiber network. Ensure the complementary downstream (BX-D) transceiver is installed on the far end using the matching wavelength pair. Configure link settings on network equipment as required for 10 Gbit/s operation and verify optical link status and signal levels via the device management interface or optical diagnostic functions.
Usage recommendations
To maintain reliable performance, use clean single-mode LC patch cords, handle the transceiver by the housing to avoid ESD or contamination, and observe manufacturer-recommended operating temperature and optical power budgets. Verify wavelength pairing and compatibility with the remote transceiver before deployment.
