SFP+ transceiver CBO SFP-10G-BX-D-40KM — 10 Gbit/s, singlemode, 40 km

The CBO SFP-10G-BX-D-40KM is an SFP+ fiber optic transceiver module that supports 10 Gbps data transfer over single-mode fiber for distances up to 40 km. It provides a compact, hot-pluggable interface suitable for installation in switches, routers and media converters. The transceiver implements a bi-directional wavelength design to enable point-to-point and uplink connections over a single single-mode fiber, making it appropriate for carrier, enterprise and data center networks that require long-reach 10G links.

Advantages

The module delivers 10 Gbps throughput while maintaining low power consumption and small form-factor compatibility with SFP+ ports. Its single-mode, long-reach capability up to 40 km reduces the need for intermediate regeneration, and the hot-pluggable design simplifies maintenance and upgrades without powering down network equipment. The bi-directional operation conserves fiber infrastructure by using different transmit and receive wavelengths on a single fiber.

Suitable for

• Long-distance uplinks between aggregation switches and core routers
• Point-to-point links in carrier and metro networks
• Data center interconnects where single-mode 10G links are required
• Media converters and equipment with SFP+ interfaces

Key specifications

• Data rate: 10 Gbps
• Fiber type: single-mode fiber (SMF)
• Maximum reach: up to 40 km (depending on fiber and link margin)
• Form factor: SFP+ (hot-pluggable)
• Transmission: bi-directional (different transmit and receive wavelengths over one fiber)
• Typical power consumption: low (compatible with standard SFP+ power envelopes)

How to use

Insert the transceiver into an available SFP+ slot on a compatible switch, router or media converter until it clicks into place. Connect a single-mode fiber patch cable using appropriate LC connectors and ensure correct orientation for transmit and receive channels according to device documentation. Verify link status on both ends and configure the network equipment for 10 Gbps operation if needed. When removing the module, power down the port if the platform recommends it or use the software disable procedure before hot-unplugging to avoid link flaps.

Recommendations

Use single-mode fiber with LC connectors and verify fiber cleanliness before insertion. Match transmit and receive wavelengths on both endpoints and confirm that link budget and fiber attenuation support the required 40 km reach. Follow equipment vendor compatibility guidelines and firmware requirements to ensure full functionality.
