SFP+ fiber transceiver CBO SFP-10G-BX-U-40KM-MT-BO 10 Gbps, single-mode LC, 40 km, BiDi

SFP-10G-BX-U-40KM-MT-BO is a BlueOptics CBO SFP+ fiber transceiver module that delivers 10 Gbps over single-mode fiber with an LC connector and a reach of up to 40 km. The BiDi (bidirectional) design transmits and receives on different wavelengths over a single fiber pair, enabling duplex communication while reducing fiber count and port usage. The module is intended for installation in SFP+ compatible ports of switches, routers and media converters to create long-distance 10G links in metro, campus and data center environments.

Advantages

The transceiver supports full 10 Gbps line rate with low power consumption and complies with industry SFP+ form-factor specifications for hot-pluggable operation. Its BiDi architecture minimizes fiber infrastructure requirements and simplifies cabling between sites. The single-mode design and LC connector ensure compatibility with standard SMF cabling, while the optical reach of 40 km covers extended connections without the need for signal regeneration.

Suitable for

• Long-distance 10G links between buildings or data center floors
• Metro and campus backbone connections
• Upgrading switch and router uplinks to 10 Gbps
• Media converter and aggregation equipment interconnects

Key specifications

• Data rate: 10 Gbps
• Fiber type: Single-mode fiber (SMF)
• Connector: LC duplex (BiDi uses single fiber pair)
• Optical reach: up to 40 km
• Transmission mode: BiDi (bidirectional wavelengths over one fiber pair)
• Form factor: SFP+ (hot-pluggable)
• Typical power consumption: low (SFP+ class)

How to use

Install the module into an SFP+ port on a compatible switch, router or media converter while the host device is powered on or off, following hot-plug guidelines from the equipment vendor. Connect the LC-terminated single-mode fiber patch cable between modules at both ends, ensuring correct orientation for transmit and receive wavelengths when using BiDi links. Verify link status and speed on the host device and, if required, adjust port settings such as speed or auto-negotiation according to the network design.

Recommendations

Use single-mode LC patch cables and check compatibility with the host equipment for SFP+ modules. When deploying BiDi transceivers, ensure matching wavelength pairs on both ends and test signal quality for links approaching the 40 km limit. Keep connectors and fiber clean and follow standard fiber-handling practices to maintain optimal optical performance.
