Network QSFP Transceiver BlueOptics BO25K13630D 40GBASE-ER4L 30 km

BlueOptics BO25K13630D is a QSFP 40GBASE-ER4L optical transceiver engineered for long-reach 40 Gbps Ethernet links over single-mode fiber. The module fits QSFP form-factor ports on compatible switches and routers and provides high-bandwidth connectivity for backbone links, data center interconnects and carrier-grade transport. It supports transmission distances up to 30 km, enabling low-latency links between sites without intermediate amplification for typical single-mode fiber deployments.

Advantages

The transceiver offers a compact QSFP package that consolidates four 10 G lanes into a single 40 G interface, reducing port density and cabling complexity. Built for long-reach operation, it delivers stable performance across extended distances with low power consumption and industry-standard electrical and optical interfaces for interoperability. Its design targets reliable data transport with consistent optical output and receive sensitivity suited to long-haul single-mode fiber links.

Suitable for

• Data center interconnects between facilities up to 30 km apart
• Metro and backbone Ethernet links requiring 40 G capacity
• Carrier and telecom aggregation links over single-mode fiber
• High-bandwidth campus or enterprise uplinks

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Standard: 40GBASE-ER4L
• Data rate: 40 Gbps (aggregate, four 10 G lanes)
• Fiber type: single-mode fiber (SMF)
• Maximum reach: up to 30 km (over standard SMF, typical conditions)
• Wavelength: multiple-lane wavelengths aggregated for ER4L operation
• Connector: compatible with standard duplex single-mode fiber connectors via appropriate breakout or MTP/MPO interface as supported by host equipment
• Typical power consumption: low-power QSFP class (refer to host equipment for exact values)

How to use

Insert the QSFP transceiver into a compatible QSFP slot on a switch, router or optical transponder following the host vendor’s hot-plug guidelines. Connect single-mode fiber using the appropriate cable or breakout assembly that matches the transceiver interface and the host panel. Verify link status and configure the host port for 40G operation as required. Monitor optical levels and alarms via the host device to ensure reliable operation across the deployed fiber span.

Recommendations

Install the module in clean, ESD-protected conditions and use certified single-mode fiber and connectors. Perform end-to-end loss-budget calculations for the 30 km span including connector and splice losses. Test the link during commissioning and maintain proper dust caps when the module is not connected.
