SFP+ transceiver CBO SFP-10G-BX-U-40KM-DL-BO 10 Gbit/s single‑fiber LC 40 km

CBO SFP-10G-BX-U-40KM-DL-BO is an SFP+ optical transceiver module that supports 10 Gbit/s data transmission over a single optical fiber using BiDi (bidirectional) technology with an LC connector. The module is designed for long-distance point-to-point links and uplink ports in switches and routers, offering a compact, hot-pluggable form factor suitable for standard SFP+ cages and ports. It provides a reach of up to 40 km over single-mode fiber, enabling high-speed Ethernet and fiber channel connectivity for data center and metropolitan network segments.

Advantages

The transceiver delivers 10 Gbit/s throughput on a single-fiber link, reducing cabling complexity by using bidirectional transmission on one strand. Its LC connector and SFP+ form factor ensure compatibility with a wide range of network equipment that supports standard SFP+ modules. Hot-pluggable design allows replacement or upgrades without powering down equipment, and the 40 km reach supports extended links between network sites and distribution points.

Suitable for

• 10 Gigabit Ethernet uplinks between switches and routers
• Long-distance point-to-point fiber links within metropolitan or campus networks
• Fiber channel or storage area network interconnects requiring single-fiber solutions
• Network equipment with SFP+ ports that support single-fiber BiDi transceivers

Key specifications

• Data rate: 10 Gbit/s
• Interface: SFP+ hot-pluggable form factor
• Connector type: LC duplex-style interface for single-fiber BiDi
• Transmission mode: Single-fiber bidirectional (BiDi/BX-U)
• Maximum reach: up to 40 km over single-mode fiber
• Application: 10 Gigabit Ethernet and compatible fiber channel links

How to use

Insert the SFP+ transceiver into an available SFP+ port on a compatible switch, router or media converter while the device is powered on; the hot-pluggable design supports installation without shutting down equipment. Connect the LC-terminated single-mode fiber cable with the appropriate polarity for bidirectional operation, and verify link status via the host device LEDs or management interface. Ensure the host device supports single-fiber BiDi modules and configure the port speed and duplex settings if necessary.

Recommendations

Use ITU-T compliant single-mode fiber and LC connectors rated for long-distance links. Confirm that the networking equipment accepts third-party SFP+ BiDi modules or enable vendor transceiver support in device settings if required. For reliable operation over 40 km, verify optical budget and attenuators are not introducing excessive loss, and keep connectors clean to maintain signal integrity.
