QSFP transceiver BlueOptics BO25K13630D 40GBASE-ER4L 30 km optical module

BlueOptics BO25K13630D is a QSFP transceiver module compliant with 40GBASE-ER4L standards, designed to deliver 40 Gbps links over single-mode fiber for distances up to 30 km. The module fits QSFP ports and supports multi-channel transmission, enabling high-bandwidth aggregation and long-distance connectivity for metro and campus backbone links, data center interconnects, and carrier networks. It is intended for use with compatible QSFP equipment and optical line systems that accept 40GBASE-ER4L optics.

Advantages

The transceiver provides reliable long-reach 40 Gbps performance with low power consumption and compact QSFP form factor. Multi-channel operation supports parallel optical lanes for stable data throughput and efficient aggregation. Its single-mode fiber compatibility and extended reach make it suitable for inter-building and metropolitan links while allowing straightforward installation into standard QSFP ports.

Suitable for

• Metro and campus backbone uplinks
• Data center interconnects between sites up to 30 km apart
• Carrier and service provider optical links
• High-bandwidth aggregation and switch-to-switch connections

Key specifications

• Nominal data rate: 40 Gbps
• Standard: 40GBASE-ER4L
• Maximum reach: up to 30 km over single-mode fiber
• Form factor: QSFP
• Optical type: single-mode, multi-channel (parallel lanes)
• Interface: QSFP electrical/optical connector compatibility
• Operating environment: designed for typical network equipment ambient temperatures

How to use

Install the transceiver into a compatible QSFP port on a switch, router or optical transponder while the host device is powered down or following the equipment vendor's hot-plug procedures. Connect single-mode fiber using appropriate LC/MPO patching or breakout assemblies as required by the multi-channel optical interface. Verify link status and diagnostics via the host device management interface and ensure fiber routing and optical power budgets meet the 30 km reach requirement.

Recommendations

Use certified single-mode fiber with correct connectors and maintain clean fiber endfaces. Confirm compatibility with the host QSFP port and check optical power budget and wavelength allocation before deployment. For reliable operation over long distances, follow vendor guidance on temperature range, cable type, and connector cleanliness.
