SFP+ transceiver CBO SFP-10G-BX-U-40KM-LO-BO 10 Gbps single-mode LC 40 km bidirectional

CBO SFP-10G-BX-U-40KM-LO-BO is an SFP+ optical transceiver module that provides 10 Gbps connectivity over single-mode fiber with an LC connector. Engineered for bidirectional (BX) operation, the module transmits and receives on separate wavelengths over a single fiber pair, enabling long-distance 10GbE links up to 40 km. It is intended for use in switches, routers and telecom equipment to extend Ethernet connections and simplify fiber cabling requirements.

Advantages

The module supports a standard 10 Gbps data rate and is compatible with common SFP+ slots, enabling high-bandwidth links without replacing networking equipment. Its bidirectional design reduces fiber count by carrying transmit and receive signals on the same fiber pair, which can lower cabling costs and simplify installations. With an LC connector and single-mode optics optimized for distances up to 40 km, the transceiver is suitable for metropolitan and long-reach access links while maintaining low power consumption typical of SFP+ form factors.

Suitable for

• 10 Gigabit Ethernet uplinks between switches and aggregation points
• Long-reach fiber connections in campus and metropolitan networks
• Optical links in routers, firewalls and telecom equipment with SFP+ ports
• Fiber infrastructure upgrades where reducing fiber pairs is required

Key specifications

• Data rate: 10 Gbps
• Fiber type: single-mode fiber (SMF)
• Maximum reach: up to 40 km
• Connector type: LC duplex (bidirectional over single fiber pair)
• Operation: bidirectional (BX), separate TX/RX wavelengths over one fiber pair
• Form factor: SFP+ (hot-pluggable)
• Typical power profile: low-power SFP+ class

How to use

Install the transceiver into a compatible SFP+ slot on your switch, router or optical device while the host port is powered down if recommended by the equipment vendor. Connect the LC fiber patch cables according to TX/RX orientation; when using bidirectional BX modules ensure the paired module at the remote end uses the complementary wavelength assignment. After insertion, verify link status and configure the host interface for 10 Gbps operation if necessary. Monitor the link for proper signal and error rates using the device management tools.

Usage recommendations

The transceiver should be matched with single-mode fiber and LC connectors and paired with a complementary BX transceiver at the remote end. Use quality single-mode patch cords and adhere to bending radius limits. Verify compatibility with the host device by checking supported SFP+ modules in vendor documentation or by testing the module in a spare port before deployment.
