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

The BlueOptics BO25K13630D is a QSFP transceiver module engineered for 40GBASE-ER4L optical links, delivering four-lane 40 Gbps aggregate throughput with a single QSFP interface and a reach of up to 30 km. Intended for long-reach connections, this module supports high-speed Ethernet and optical transport applications in data centers, metro networks, and campus interconnects. The transceiver uses multi-lane optics to convert electrical signals to optical signals and back, enabling high-density uplinks and cross-connects with compact form factor.

Advantages

The module provides extended reach of up to 30 km over single-mode fiber, enabling long-distance Ethernet links without intermediate regeneration. Its QSFP form factor supports four lanes of 10 Gbps-equivalent signaling aggregated to 40 Gbps, allowing straightforward integration into QSFP-capable switches and routers. The transceiver is suitable for high-density installations thanks to its compact size and standardized electrical and optical interfaces, and it supports hot-plug operation for maintenance flexibility.

Suitable for

• Data center uplinks and spine-to-leaf interconnects requiring long-reach links
• Metro and campus optical connections across distances up to 30 km
• 40 Gbps Ethernet and optical transport deployments
• High-density switch and router ports where QSFP modules are supported

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Data rate: 40 Gbps aggregate (4 lanes)
• Protocol: 40GBASE-ER4L Ethernet
• Maximum reach: up to 30 km over single-mode fiber
• Optical interface: four-lane single-mode fiber
• Typical application: long-reach optical links for data centers and metro networks

How to use

Install the BlueOptics QSFP transceiver into a compatible QSFP port on the switch or router until it seats firmly and the module latch engages. Connect appropriate single-mode fiber cabling terminated for the module's optical interface, following the equipment vendor's port labeling and fiber polarity guidelines. Verify link status through the network device's interface LEDs or management console and confirm the device negotiates at 40 Gbps as expected. For removal, power down the port if required by the host device, release the module latch, and pull the transceiver straight out to avoid damaging the cage or fiber connectors.

Recommendations

Use certified single-mode fiber with proper cleaning of connectors before insertion. Ensure the host equipment supports 40GBASE-ER4L and QSFP modules, and verify transceiver compatibility lists if available. Maintain ambient conditions within the module's specified operating temperature and avoid bending fiber beyond recommended radii to preserve link performance over long distances.
