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

BlueOptics BO25K13630D is a hot-pluggable QSFP transceiver designed for 40GBASE-ER4L links over single-mode fiber at 1310 nm, providing up to 30 km reach. The module aggregates four independent 10 Gbit/s lanes in a compact QSFP form factor, enabling high-speed uplinks and long-distance connectivity for data centers, carrier networks and campus backbones. Its single-mode operation and LC optical interface make it suitable for metro and long-reach applications where stable 40 Gbit/s links are required.

Advantages

The transceiver offers long-reach performance up to 30 km while maintaining a four-lane 10 Gbit/s per lane architecture in a small QSFP package, allowing dense aggregation and efficient use of fiber infrastructure. Hot-pluggable design simplifies maintenance and replacements without interrupting adjacent ports. Operating at 1310 nm on single-mode fiber reduces dispersion effects on extended links and ensures compatibility with typical carrier and data center fiber deployments.

Suitable for

• Long-distance data center interconnects
• Carrier and metro aggregation links
• Campus backbone and POP connections
• High-speed uplinks between switches and routers

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Data rate: 40 Gbit/s (4 × 10 Gbit/s lanes)
• Optical wavelength: 1310 nm
• Maximum reach: up to 30 km over single-mode fiber
• Optical interface: LC duplex (single-mode)
• Hot-pluggable: yes

How to use

Handle the QSFP transceiver by its housing, avoiding contact with the optical connector endfaces. Insert the module into a compatible QSFP slot until it seats and the latch engages. Connect single-mode LC fiber patch cords to the module’s ports, ensuring correct transmit/receive orientation. Monitor link status through the host device and perform any necessary configuration for 40GBASE-ER4L operation on the connected switch or router. When removing the module, power down or follow hot-swap procedures recommended by the host device and use the ejector latch to extract the transceiver.

Recommendations

Use high-quality single-mode LC patch cords and maintain clean optical endfaces to ensure reliable long-distance links. Verify compatibility with the host system’s QSFP specifications and check link settings for 40GBASE-ER4L mode. Store unused transceivers in antistatic packaging and protect connectors with dust caps when not in use.
