QSFP optical transceiver BlueOptics BO25K13630D 40GBASE-ER4L 1310nm 30 km

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

Key specifications

• Transmission speed: 40 Gbit/s (aggregated)
• Wavelength: 1310 nm
• Maximum reach: up to 30 km over single-mode fiber
• Form factor: QSFP (quad small form-factor pluggable)
• Fiber type: single-mode fiber (SMF)
• Optical interface: four parallel lanes supporting 40GBASE-ER4L operation

How to use

Install the QSFP transceiver into a compatible QSFP port on a switch, router or media converter following standard hot-plug procedures. Ensure that connected fiber is single-mode and that fiber connectors and patch cords meet the system’s optical budget. Configure the network device for 40G operation and verify link status via the device management interface. Use appropriate DOM/SFF diagnostics if supported to monitor optical power and temperature.

Recommendations

Use this transceiver in links where a reliable 40 Gbit/s single-mode connection is required over distances up to 30 km. Verify compatibility with the host device and use quality single-mode patch cords and connectors. Regularly inspect and clean fiber endfaces and monitor diagnostics to maintain optimal performance.
