SFP+ transceiver CBO SFP-10G-BX-U-40KM-MA-BO 10 Gbit/s singlemode LC, 40 km, BX-U

SFP+ transceiver CBO SFP-10G-BX-U-40KM-MA-BO provides 10 Gbit/s optical connectivity over single‑mode fiber using an LC connector and supports a maximum link length of 40 km. The BX-U designation indicates this module transmits on the upstream wavelength in bidirectional single‑fiber installations, enabling full duplex communication over a single strand of fiber. The SFP+ form factor ensures compatibility with a wide range of switches, routers and optical equipment designed for small form-factor pluggable modules.

Advantages

This transceiver delivers 10 Gbit/s throughput with low power consumption and a compact SFP+ footprint for space-constrained racks and modules. Its single‑mode design and LC interface provide stable long‑reach performance up to 40 km, while the BX-U wavelength plan enables bidirectional communication on a single fiber, reducing fiber infrastructure requirements. Built to industry optical standards, the module supports hot‑swappable installation and interoperates with compliant network hardware for flexible deployment.

Suitable for

• Data center uplinks and server aggregation where 10 Gbit/s links are required
• Metro and carrier networks needing long‑reach single‑mode connections
• Bidirectional single‑fiber links to reduce fiber cabling between sites
• Edge and access switches that accept SFP+ modules with LC connectors

Key specifications

• Data rate: 10 Gbit/s
• Fiber type: single‑mode (SMF)
• Connector: LC duplex/bi‑directional single‑fiber compatible
• Maximum reach: up to 40 km (depending on fiber and link loss)
• Wavelength plan: BX‑U (upstream wavelength on this module)
• Form factor: SFP+ hot‑swappable
• Typical power consumption: industry‑standard low power for SFP+ modules

How to use

Insert the SFP+ transceiver into a compatible SFP+ slot on a switch, router or optical device while the device is powered on or off, as supported by the host equipment. Terminate the single‑mode fiber to the LC connector and ensure the paired module at the remote end uses the complementary BX‑D/BX‑O wavelength assignment for bidirectional operation. Verify link status and adjust device port settings for 10 Gbit/s as required by the network equipment. Monitor optical power and link performance to ensure proper operation across the intended 40 km span.

Recommendations

Use this module in networks with compatible SFP+ ports and ensure transceiver wavelength plans match on both ends of a bidirectional link. For link budgets approaching 40 km, check fiber attenuation, connector losses and any inline components; use proper cleaning and handling to maintain optical performance.
