Network QSFP transceiver BlueOptics BO25K13630D 40GBASE-ER4L 40 Gbps 30 km

BlueOptics BO25K13630D is a QSFP form-factor 40GBASE-ER4L optical transceiver that delivers 40 Gbps connectivity over single-mode fiber for links up to 30 km. The module is hot-pluggable and intended for use in high-density switches and routers where long-reach 40G connections are required. It supports four parallel lanes aggregated to 40 Gbps and is suitable for data center interconnects, metro transport and carrier networks demanding extended reach.

Advantages

The transceiver provides long-reach 40G connectivity in a compact QSFP package, enabling high port density and simplified cabling compared with discrete optics. Hot-pluggable design allows for tool-free installation and replacement without disrupting system operation. Designed for single-mode fiber, the module supports stable performance over distances up to 30 km and integrates with standard 40GBASE-ER4L interfaces for interoperability with compatible networking equipment.

Suitable for

• Data center interconnects and spine-to-spine links
• Metro aggregation and campus backbone connections
• Carrier Ethernet and service provider transport
• High-density switches and routers requiring 40G long-reach ports

How to use

Install the QSFP transceiver into a compatible QSFP port on your switch or router following the equipment manufacturer’s insertion and handling guidelines. Connect single-mode fiber using appropriate LC or MPO/MTP connectors as required by the host hardware and patching infrastructure. Verify link negotiation and status via the host device management interface and monitor signal and temperature parameters if supported by the equipment. When replacing the module, power down procedures are generally not required thanks to the hot-pluggable design; follow your system vendor recommendations to avoid momentary link interruptions.

Recommendations

Use high-quality single-mode fiber and follow standard installation practices for fiber routing, strain relief and connector cleaning to maintain signal integrity over long distances. Ensure compatibility with the host device’s 40GBASE-ER4L implementation and consult equipment documentation for supported transceiver lists and firmware requirements.
