Optical QSFP Transceiver BlueOptics BO25K13630D 40GBASE-ER4L 30 km 1310 nm

BlueOptics BO25K13630D is a QSFP optical transceiver designed for 40GBASE-ER4L applications. The module transmits at 1310 nm and supports aggregate data rates of 40 Gbit/s, enabling long-reach single-mode fiber links up to 30 km. Its standard QSFP form factor ensures compatibility with a wide range of switches and routers that accept quad small form-factor pluggable devices, making it suitable for metro and long-distance data center interconnects.

Advantages

The transceiver provides reliable 40 Gbit/s aggregation and transport over single-mode fiber for distances up to 30 km at 1310 nm. Its QSFP form factor allows high port density and straightforward hot-pluggable installation. The module is engineered for stable operation in carrier-class and data center environments, offering predictable link performance for metro, campus and long-reach connections.

Suitable for

• Long-reach 40 Gbit/s links between data centers and metro nodes
• Aggregation and transport in carrier and service provider networks
• High-density 40G ports in enterprise core and spine switches
• Upgrades from multiple 10G links to a single 40G trunk over single-mode fiber

Key specifications

• Form factor: QSFP (quad small form-factor pluggable)
• Data rate: 40 Gbit/s aggregate
• Wavelength: 1310 nm
• Maximum link distance: up to 30 km over single-mode fiber
• Fiber type: single-mode
• Application: 40GBASE-ER4L long-reach Ethernet

How to use

Insert the QSFP transceiver into a compatible QSFP port on the switch or router while the host device is powered on or off, following the equipment manufacturer's guidance for hot-plug handling. Connect single-mode fiber cables with appropriate LC connectors to the transceiver ports, ensure correct fiber routing and secure connections, then verify link status via the host device management interface. Configure the network device for 40G operation as required and monitor signal health and error counters during initial deployment.

Recommendations

Use certified single-mode fiber with proper attenuation budget for 30 km links, maintain clean connector endfaces, and follow ESD precautions when handling the QSFP module. Validate interoperability with the host equipment and test link performance after installation to ensure expected 40GBASE-ER4L operation.
