Optical QSFP Transceiver BlueOptics BO25K13630D 40GBASE-ER4L 40Gbps 30 km

BlueOptics BO25K13630D is a QSFP optical transceiver module designed for 40GBASE-ER4L applications, delivering 40 Gbps throughput over single-mode fiber with a maximum reach of up to 30 km. The module is compatible with QSFP form-factor ports commonly found in high-density switches and routers, enabling long-distance links for metro and data center interconnects while maintaining low latency and full-duplex operation.

Advantages

The transceiver offers a compact QSFP form factor that supports four-lane 40 Gbps operation, optimized for long-reach single-mode fiber environments. It provides predictable optical performance across extended distances and is suitable for integration into existing optical network infrastructures without requiring protocol conversion. The module's design supports hot-pluggable installation and standard QSFP electrical and optical interfaces for interoperability with compatible network equipment.

Suitable for

• Data center interconnects between racks or sites up to 30 km apart
• Metro area networks requiring high-bandwidth, low-latency optical links
• High-density switches and routers with QSFP ports
• Network upgrades where long-reach single-mode fiber connections are needed

Key specifications

• Form factor: QSFP (Quad Small Form-Factor Pluggable)
• Data rate: 40 Gbps (four lanes aggregated)
• Mode: Single-mode fiber
• Maximum reach: up to 30 km over single-mode fiber
• Application standard: 40GBASE-ER4L
• Interface: LC (or compatible optical connector for single-mode duplex)

How to use

Insert the QSFP transceiver into a compatible QSFP port on a switch or router while the host device is powered on or in accordance with the equipment vendor's hot-plug guidance. Connect single-mode fiber patch cables to the transceiver's optical ports, ensuring correct transmit/receive orientation. Verify link status and optics diagnostics through the network device management interface or monitoring tools. Follow the network equipment vendor's instructions for enabling and configuring 40GBASE-ER4L links and for any required link aggregation or protocol settings.

Recommendations

Use certified single-mode fiber with appropriate attenuation characteristics and maintain patch panel cleanliness to ensure optimal signal quality. Confirm compatibility with the host device's QSFP port and consult device documentation for supported optical modules and firmware requirements. For reliable long-distance links, test end-to-end link performance and monitor optical power and temperature parameters during initial deployment.
