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

BlueOptics BO25K13630D is a QSFP-format 40GBASE-ER4L optical transceiver designed for 40 Gbps links over long-reach single-mode fiber. Operating at 1310 nm with support for distances up to 30 km, this hot-pluggable module is intended for use in switches, routers and other optical networking equipment that require 40G ER4L specifications. The compact QSFP form factor consolidates four lanes into a single pluggable interface, enabling high-density uplinks and interconnects in data center and metro environments.

Advantages

The transceiver provides long-reach single-mode connectivity at 40 Gbps and is hot-pluggable for in-service replacement or upgrades without downtime. Its QSFP form factor allows high port density while maintaining compatibility with equipment that accepts QSFP 40G modules. The 1310 nm wavelength and ER4L specification enable reliable multi-lane transmission over extended distances, suitable for data center interconnect and metropolitan links.

Suitable for

• Data center interconnects requiring 40 Gbps links
• Metro network links and long-reach backbone connections
• Switches and routers with QSFP 40G interfaces
• Optical equipment deployments needing hot-pluggable 40G modules

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Protocol: 40GBASE-ER4L
• Data rate: 40 Gbps aggregate
• Wavelength: 1310 nm
• Maximum reach: up to 30 km over single-mode fiber
• Connector type: duplex optical interface (compatible with standard QSFP adapters)
• Hot-pluggable: supports live insertion and removal

How to use

Insert the QSFP transceiver into a compatible QSFP port on a switch, router or optical transponder while the device is powered on; the hot-pluggable design allows installation without shutting down the host. Connect single-mode fiber with appropriate LC/duplex connectors or matching patch panels following standard fiber handling practices. Verify link status through the host device management interface and ensure transmit/receive lanes are mapped according to the equipment documentation. Monitor optical power and error statistics after installation to confirm proper operation.

Recommendations

Use certified single-mode fiber and compatible QSFP cage or adapter components. Observe ESD precautions when handling the module, keep dust caps on unused connectors, and follow the equipment vendor’s optics compatibility guidelines. For reliable long-reach performance, ensure link loss budget and fiber route meet the 30 km specification and maintain proper connector cleanliness.
