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

BlueOptics BO25K13630D is a hot-pluggable QSFP transceiver module engineered for 40GBASE-ER4L links at 1310 nm, supporting four-lane aggregation to deliver 40 Gbit/s over single-mode fiber with a transmission reach of up to 30 km. The module is intended for long-reach optical uplinks in data centers, carrier networks and enterprise backbones where extended distance and reliable high-speed connectivity are required.

Advantages

The QSFP form factor provides compact, hot-swappable deployment for dense switch and router ports while minimizing downtime during maintenance. Support for 1310 nm four-lane transmission enables long-reach single-mode fiber connectivity up to 30 km, combining high throughput with extended distance. The module is designed for interoperability with standard 40GBASE-ER4L links and offers consistent optical performance for uplink and aggregation applications.

Suitable for

• Long-reach optical uplinks between switches and routers in data centers
• Carrier and metro network aggregation links over single-mode fiber
• Enterprise backbone connections requiring 40 Gbit/s and extended reach
• High-density installations where hot-pluggable QSFP modules simplify maintenance

Key specifications

• Interface: QSFP (Quad Small Form-factor Pluggable)
• Data rate: 40 Gbit/s (four aggregated lanes)
• Wavelength: 1310 nm
• Reach: up to 30 km over single-mode fiber
• Optical type: long-reach 4-lane module (ER4L)
• Hot-pluggable design for in-service replacement

How to use

Insert the QSFP transceiver into a compatible QSFP port on a switch, router or optical transport device while the host is powered on to take advantage of the hot-pluggable capability. Ensure the transceiver is seated securely and latched, then connect single-mode fiber using appropriate connectors and follow link bring-up procedures on the host device. Verify link status and optical parameters via the host interface or management software, and monitor signal quality to confirm reliable operation at the required distance.

Recommendations

Use single-mode fiber with suitable connectors and verify fiber attenuation for links approaching the 30 km range. Ensure compatibility with the host equipment's QSFP ports and firmware, and perform optical power and diagnostic checks after installation. Handle the module following standard ESD precautions and store protective dust caps on unused optical interfaces.
