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

BlueOptics BO25K13630D is a QSFP form-factor 40GBASE-ER4L optical transceiver that operates at 1310 nm and supports up to 30 km reach over single-mode fiber. Designed for high-speed long-reach Ethernet links, this hot-pluggable module provides 40 Gbps aggregate bandwidth in a compact QSFP package, enabling interconnects between data centers and metro network segments while maintaining compatibility with standard QSFP ports.

Advantages

This BlueOptics transceiver delivers long-reach performance in a QSFP form-factor, combining compact size with 40 Gbps capacity. It supports hot-plug insertion for minimal service interruption during upgrades or replacements. Built for single-mode fiber links, the module provides a predictable 30 km reach at the specified wavelength, making it suitable for cost-effective metro and inter-site connectivity. The device adheres to common 40GBASE-ER4L functional characteristics, enabling straightforward integration with compatible networking equipment.

Suitable for

• Data center interconnects between buildings or campuses
• Metro area network links requiring 30 km reach
• Upgrades from lower-rate optics to 40 Gbps QSFP ports
• Long-reach Ethernet aggregation and uplink interfaces

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Data rate: 40 Gbps aggregate
• Standard: 40GBASE-ER4L
• Wavelength: 1310 nm
• Maximum reach: up to 30 km over single-mode fiber
• Connector type: compatible with standard single-mode fiber connectors (e.g., LC via breakout/adapter)
• Hot-pluggable design for in-service replacement

How to use

Install the transceiver into a compatible QSFP port on your switch or router while observing ESD precautions. Connect single-mode fiber cables using appropriate adapters or a QSFP-to-LC breakout harness if linking to multiple LC ports. After insertion, verify the link status and data rate on the host device and ensure transceiver settings (if any) match the network configuration. For best results, check fiber cleanliness, correct patching, and link diagnostics reported by the networking equipment.

Recommendations

Use this module in single-mode fiber infrastructure with clean connectors and proper fiber management. Confirm compatibility with the host device's supported optics list and perform link tests after installation. For runs approaching the 30 km limit, verify loss budget and consider dispersion or connector loss to ensure reliable operation.
