Network QSFP transceiver BlueOptics BO25K13630D 40GBASE-ER4L 30 km

BlueOptics BO25K13630D is a QSFP network transceiver that implements 40GBASE-ER4L links over single-mode fiber for distances up to 30 km. The module delivers quad-lambda 40 Gbps optical connectivity in a hot-pluggable QSFP form factor, suitable for high-speed data center interconnects, aggregation layers and metropolitan fiber links. It uses long-reach optics designed to maintain signal integrity across extended single-mode fiber runs while remaining compatible with standard 40G Ethernet equipment from switches, routers and optical multiplexers.

Advantages

The transceiver supports long-reach 40G transmission over single-mode fiber to 30 km, enabling extended link distances without intermediate regeneration. Its QSFP hot-pluggable form factor simplifies installation and replacement in active racks. The quad-lambda architecture provides four parallel 10 Gbps lanes aggregated to 40 Gbps, which helps preserve compatibility with existing 10G optical infrastructures and simplifies migration paths. The module is designed for stable optical performance and interoperability with standard 40G Ethernet ports.

Key specifications

• Form factor: QSFP (hot-pluggable)
• Standard: 40GBASE-ER4L
• Fiber type: single-mode fiber (SMF)
• Maximum reach: up to 30 km over SMF
• Data rate: aggregate 40 Gbps (4 × 10 Gbps lanes)
• Wavelength: quad-lambda optical architecture

How to use

Insert the QSFP transceiver into a compatible QSFP port on the switch, router or optical device while the host system is powered according to the equipment vendor's hot-plug guidelines. Connect single-mode fiber patch cords with appropriate connectors and ensure correct polarity. Verify link status and signal parameters through the host device management interface; allow a short stabilization time for the optical link to reach nominal parameters. If necessary, consult the switch or router documentation for SFP/QSFP port configurations and lane mapping for 40GBASE-ER4L operation.

Recommendations

Use single-mode fiber rated for long-reach transmission and keep connectors clean to minimize insertion loss. Verify fiber attenuation and end-to-end loss budgets for 30 km links, and choose appropriate fiber routing to avoid excessive bends. Ensure firmware and transceiver compatibility with the host equipment and follow ESD precautions when handling the module.
