SFP+ transceiver CBO SFP-10G-ER 10G 40 km

CBO SFP-10G-ER 10G 40km is an SFP+ optical transceiver module that supports 10 Gbps data rates over single-mode fiber with a reach of up to 40 kilometres. The hot-pluggable, compact form factor is intended for use in high-speed uplinks, long-distance connections and backbone links in data centres, campus networks and telecom equipment. The module provides a standard SFP+ electrical interface and a duplex optical interface for integration into compatible switches, routers and network appliances.

Advantages

The transceiver offers reliable 10G connectivity over extended distances without the need for repeaters, enabling network consolidation and simplified fiber runs. Its single-mode design and industry-standard SFP+ form factor ensure broad compatibility with equipment that accepts SFP+ optical modules. Hot-pluggable operation allows insertion or removal without powering down the host device, minimising maintenance windows and reducing downtime.

Suitable for

• Data centre uplinks between aggregation and core switches
• Campus backbone connections and inter-building links
• Carrier and telecom long-reach 10G links
• High-speed server-to-switch interconnects where single-mode fiber is used

Key specifications

• Data rate: 10 Gbps
• Reach: up to 40 km on single-mode fiber
• Optical interface: duplex single-mode fibre
• Form factor: SFP+ (hot-pluggable)
• Wavelength: compatible with long-reach 10G optics (ER class)
• Typical application: long-distance 10 Gigabit Ethernet and Fibre Channel links

How to use

Install the module into an SFP+ slot of a compatible switch, router or network appliance until it seats securely, then connect the duplex single-mode fiber cable with the correct polarity. Configure the host port for 10 Gbps operation if required by the device management interface. Monitor link status LEDs on the host device to verify the link; the module is hot-pluggable so it can be inserted or removed while the system is powered, following the host vendor's hot-swap procedures.

Recommendations

Use quality single-mode fiber and proper LC connectors to maintain signal integrity over long distances. Ensure transceiver compatibility with the host device and verify fibre launch power and receiver sensitivity for the intended span. Store unused modules in anti-static packaging and avoid touching the optical interfaces; clean connectors before mating to prevent signal loss.
