SFP+ transceiver CBO SFP-10G-BX-D-40KM-PA-BO 10 Gbit/s single‑mode LC bidirectional 40 km

Compact SFP+ transceiver CBO SFP-10G-BX-D-40KM-PA-BO provides 10 Gbit/s optical connectivity over single‑mode fiber using an LC connector. The BX‑D bidirectional module supports up to 40 km reach by transmitting and receiving on different wavelengths over a single fiber, allowing long‑distance links without installing a paired fiber. Its SFP+ form factor preserves port density in switches and servers while delivering 10 Gigabit Ethernet or other 10 Gbit/s optical interfaces for data center interconnects, metro aggregation and long‑reach uplinks.

Advantages

This SFP+ transceiver combines small form factor and long reach: it supports 10 Gbit/s throughput in a compact SFP+ package and reaches up to 40 km over single‑mode fiber. Bidirectional (BX‑D) operation reduces fiber cabling requirements by using a single strand for both directions. The LC connector ensures compatibility with common fiber patch panels and jumpers, and the module is designed for straightforward hot‑plug installation into standard SFP+ ports.

Suitable for (tasks / use cases)

• Data center server and switch uplinks where port density matters
• Metro and campus aggregation links spanning up to 40 km
• Long‑reach fiber uplinks between buildings or sites using single fiber
• 10 Gigabit Ethernet links in environments that require LC connectors and SFP+ modules

Key specifications

• Data rate: 10 Gbit/s
• Fiber type: single‑mode fiber
• Connector: LC duplex (bidirectional single fiber operation)
• Transmission distance: up to 40 km
• Operation: bidirectional (different TX/RX wavelengths on one fiber)
• Form factor: SFP+ (10 Gigabit small form‑factor pluggable)

How to use

Insert the transceiver into a compatible SFP+ port on your switch, router or host adapter while the device is powered on or off, following the equipment manufacturer's hot‑plug guidance. Connect an LC single‑mode fiber patch cable to the module; ensure TX and RX wavelength pairing is correct when linking to a complementary BX‑type transceiver on the remote end. Check the link status in the host device software or LEDs and verify correct speed and optical budget for the planned distance.

Recommendations

Use certified single‑mode LC patch cords and verify that the remote module supports BX bidirectional operation with complementary wavelengths. Keep fiber connectors clean and inspect transceiver ports before connection to maintain signal quality and expected reach.
