Optický QSFP transceiver BlueOptics BO25K13630D 40GBASE-ER4L 40 Gbit/s 1310 nm 30 km

BlueOptics BO25K13630D is a QSFP optical transceiver designed for 40GBASE-ER4L links. Operating at a central wavelength of 1310 nm, this 40 Gbps module supports single-mode fiber connections for long-reach transmission up to 30 km. The QSFP form factor provides four lanes in a compact footprint, making it suitable for high-density switches and routers in data center uplinks, campus aggregation and metro interconnects where extended fiber reach is required.

Advantages

The module supports 40 Gbps aggregated bandwidth while maintaining a small QSFP package that simplifies port density and cable management. Its 1310 nm wavelength and extended reach capability reduce the need for intermediate regeneration or additional active equipment on links up to 30 km. Compatibility with standard QSFP ports allows straightforward installation and hot-pluggable operation, minimizing downtime during maintenance or upgrades.

Suitable for

• Data center uplinks and spine-to-leaf interconnects
• Metro and campus backbone links requiring up to 30 km reach
• High-speed aggregation between switches and routers
• Fiber extension between sites and equipment rooms

Key specifications

• Hot-pluggable: yes

How to use

Install the transceiver into a compatible QSFP port on a switch or router following the host equipment manufacturer’s hot-swap procedures. Connect an appropriate single-mode fiber cable and verify link status through the device management interface. Ensure the transmit and receive fibers are correctly oriented and that fiber connectors and cable cleaners are used to prevent contamination. Validate link speed and error counters after installation to confirm correct operation.

Recommendations

For reliable long-reach performance, use single-mode fiber with specified connector types, maintain clean connectors, and operate the transceiver within the host device’s supported temperature and power margins. Perform compatibility checks with the switch or router vendor to ensure full feature support and link stability.
