SFP+ transceiver CBO SFP-10G-BX-D-40KM pre 10 Gbit/s single-fiber, 40 km dosah

CBO SFP-10G-BX-D-40KM is an SFP+ transceiver module designed for 10 Gbps single-fiber links with an optical reach of up to 40 km. The module supports bi-directional transmission over a single optical fiber using separate transmit and receive wavelengths, enabling long-reach point-to-point connectivity in compact, hot-pluggable form. It is intended for use in networking equipment equipped with SFP+ ports and conforms to common optical interface expectations for high-speed links in data centers, telecom backbones and enterprise WAN segments.

Advantages

The transceiver provides 10 Gbps bandwidth in an SFP+ form factor while eliminating the need for paired fibers by using bi-directional wavelengths. Its hot-pluggable design allows insertion and removal without powering down the host device, simplifying upgrades and maintenance. With a 40 km optical range, the module supports extended reach applications and reduces dependency on intermediate aggregation points. The product is compatible with standard SFP+ ports and is suitable for use where space efficiency and long-distance single-fiber connectivity are required.

Suitable for

• Point-to-point links between data center racks or buildings over single fiber
• Metro and access network segments requiring 10 Gbps capacity with extended reach
• Telecom backbone connections and enterprise WAN links where fiber pairs are limited
• Edge and aggregation switches with SFP+ ports that need compact, hot-pluggable optics

Key specifications

• Data rate: 10 Gbps
• Optical reach: up to 40 km
• Optical interface: single-fiber, bi-directional (separate transmit and receive wavelengths)
• Form factor: SFP+
• Connector: LC duplex single-fiber bi-directional compatible (single fiber pair usage)
• Operating mode: hot-pluggable

How to use

Install the module into an available SFP+ slot on compatible networking equipment until it clicks into place. Connect a single-mode fiber with the appropriate LC connector and ensure the transmit and receive ends are matched to the corresponding wavelength on the remote module. Verify link status through the host device management interface or LED indicators. For module removal, gently depress the latch and pull the transceiver straight out while the host is powered according to the device manual.

Recommendations

Use clean, grade‑appropriate single-mode fiber and observe proper handling of optical connectors to maintain link quality. Confirm firmware or vendor compatibility with the host equipment if required, and perform optical power and link tests after installation. Avoid exposing the module to excessive mechanical stress, electrostatic discharge, or temperatures outside the equipment’s specified operating range.
