## Long description

The BlueOptics BO25K13630D QSFP optical transceiver is a 40GBASE-ER4L module operating at 1310 nm designed for single-mode fiber links with a reach of up to 30 km. It delivers 40 Gbit/s aggregated bandwidth over four parallel lanes and is intended for high-speed metro and long-reach campus connections, data center interconnects and service provider links that require extended optical reach. The transceiver supports standard QSFP form factor connectivity and is compatible with equipment that accepts QSFP 40GBASE-ER4L modules.
Advantages
The module offers 40 Gbit/s capacity with an extended single-mode reach of up to 30 km at 1310 nm, enabling longer link distances without additional amplification. Its QSFP form factor provides compact, hot-pluggable deployment for switch and router ports. Designed for professional network environments, the transceiver supports stable multi-lane operation and is suitable for aggregation and interconnect applications where predictable optical performance is required.
Suitable for
 Metro area network links with extended reach requirements
 Data center interconnects between buildings or campuses
 Service provider backbone links and aggregation ports
 High-speed trunk connections in campus networks
