SFP+ transceiver CBO SFP-10G-BX-D-40KM-EE-BO 10 Gbit/s LC single-fiber BX-D 40 km

CBO SFP-10G-BX-D-40KM-EE-BO is an SFP+ optical transceiver module that supports 10 Gbit/s bidirectional transmission over a single LC fiber using BX-D technology. The module is intended for point-to-point high-speed links in enterprise and carrier networks where fibre consolidation or limited fiber availability requires transmit and receive signals to share a single strand. It is compatible with equipment that accepts SFP+ form-factor modules and provides a compact solution for extending 10 Gigabit Ethernet or other 10 Gbit/s optical interfaces up to 40 km.

Advantages

The transceiver provides 10 Gbit/s data rate and bidirectional single-fibre operation, reducing fibre count and simplifying cabling between sites. Its LC single-fiber interface and compact SFP+ form factor enable easy installation into switches, routers and optical line cards. The 40 km reach supports medium-distance links without the need for additional amplification in typical deployments, and BX-D operation allows simultaneous transmit and receive over one strand, saving port and fibre resources.

Suitable for

• 10 Gigabit Ethernet links between buildings or data halls up to 40 km
• Carrier and metro network aggregation where fibre resources are limited
• Switches and routers with SFP+ ports requiring single-fibre bidirectional transceivers
• Optical interface upgrades to consolidate duplex fibres into single-strand links

Key specifications

• Data rate: 10 Gbit/s
• Optical interface: LC single-fiber (bidirectional BX-D)
• Maximum reach: up to 40 km over single-mode fibre
• Form factor: SFP+
• Transmission method: bidirectional on one fibre (separate TX and RX wavelengths)

How to use

Install the SFP+ transceiver into a compatible SFP+ port on the switch, router or optical device while the device is powered per the vendor's instructions. Use a single strand of single-mode LC fibre and ensure the remote endpoint uses the complementary BX configuration (opposite transmit/receive wavelengths). After physical insertion and fibre connection, verify link status and configuration in the host device's interface settings. If required, adjust interface parameters such as speed, duplex and autonegotiation according to network policies.

Recommendations

Ensure both ends of the link are using compatible bidirectional SFP+ modules with matching wavelength directions, maintain clean LC connectors to minimise insertion loss, and follow manufacturer guidance for handling electrostatic-sensitive modules. For runs approaching the 40 km limit, verify fibre attenuation and connector/splice quality to maintain reliable signal margins.
