SFP+ CBO SFP-10G-BX-U-40KM-IA-BO 10 Gbit/s Single‑mode LC BX-U 40 km

The SFP+ CBO SFP-10G-BX-U-40KM-IA-BO 10 Gbit/s Single‑mode LC BX-U 40 km is a single‑mode optical transceiver designed for 10 Gigabit Ethernet links. It supports bidirectional upstream (BX-U) operation over a single fiber strand using an LC connector, enabling long‑reach connections up to 40 kilometres. The module is intended for installation in compatible SFP+ ports of switches, routers and media converters in telecom and data‑centre environments where fibre conservation and extended reach are required.

Advantages

This SFP+ transceiver provides 10 Gbit/s bandwidth with single‑strand bidirectional transmission, reducing the need for dual‑fibre runs and simplifying fibre infrastructure. Its single‑mode design supports long distances up to 40 km, making it suitable for metro and campus links. The LC connector and common SFP+ form factor ensure compatibility with a wide range of network equipment that accepts SFP+ optical modules. The module is designed to offer stable optical performance for point‑to‑point fibre links while maintaining compact size for high‑density chassis.

Suitable for

• Long‑reach 10 Gigabit Ethernet links in metro, campus or access networks
• Data‑centre uplinks and inter‑rack connections where fibre count is limited
• Telecom installations requiring bidirectional single‑strand transmission
• Upgrading switches and routers with SFP+ slots to support 10G single‑mode links

Key specifications

• Data rate: 10 Gbit/s
• Fibre type: single‑mode
• Connector: LC
• Transmission mode: bidirectional upstream (BX‑U) over a single strand
• Maximum reach: up to 40 km
• Form factor: SFP+

How to use

Install the transceiver into a compatible SFP+ port on your switch, router or media converter until it locks into place. Connect an appropriate single‑mode fibre cable with LC connectors, ensuring the transmit and receive directions match the BX‑U operation specification. Configure the host device to enable the SFP+ port at 10 Gbit/s if necessary; the module operates transparently at the optical layer and typically requires no additional configuration. Observe standard fibre‑handling precautions: keep connectors clean, avoid bending the fibre beyond its minimum bend radius and use dust caps when the module is unused.

Recommendations

Use this module in equipment that explicitly supports SFP+ optical transceivers and bidirectional (BX) operation. For reliable long‑reach links, verify the single‑mode cable attenuation and any inline connectors or splices do not exceed the optical budget. Maintain clean LC connectors and follow manufacturer guidelines for ambient temperature and handling to ensure consistent performance.
