Optical QSFP Transceiver BlueOptics BO25K13630D 40GBASE-ER4L 1310 nm 30 km

The BlueOptics BO25K13630D is a QSFP optical transceiver engineered for 40GBASE-ER4L operation at 1310 nm, providing four independent lanes to deliver aggregate 40 Gbit/s data transmission over single-mode fiber. Designed for long-reach applications, the module supports link distances up to 30 km and fits QSFP ports used in data center switches, routers and optical transport equipment. The transceiver is suitable for uplinks and interconnects where extended-distance 40 Gb/s links and QSFP form-factor compatibility are required.

Advantages

The module offers long-reach 40 Gb/s transmission at 1310 nm with a rated maximum distance of 30 km, enabling extended interconnects without intermediate regeneration. Its QSFP form factor consolidates four optical lanes into a single pluggable unit for compact, high-density installations. The transceiver is designed for straightforward integration with standard QSFP ports and common network equipment, supporting consistent lane mapping and stable optical performance for carrier and enterprise deployments.

Suitable for

• Data center uplinks and spine-to-leaf connections requiring 40 Gb/s long-reach links
• Carrier and metro network links across single-mode fiber spans up to 30 km
• Interconnects between routers, switches and optical transport platforms

Key specifications

• Data rate: aggregate 40 Gbit/s (four 10 Gbit/s lanes)
• Wavelength: 1310 nm
• Reach: up to 30 km over single-mode fiber
• Form factor: QSFP (quad small form-factor pluggable)
• Application: 40GBASE-ER4L long-reach Ethernet

How to use

Install the transceiver into an available QSFP port on compatible switches, routers or optical transport devices following the host equipment manufacturer’s hot-plug guidelines. Connect single-mode fiber with appropriate LC/APC or LC/PC connectors as required by the link design and ensure correct lane mapping and fiber polarity. Verify link status and optical power levels in the host device management interface and monitor for alarms or loss of signal during initial commissioning.

Recommendations

Use low-loss single-mode fiber and maintain clean connector endfaces to ensure reliable 30 km performance. Confirm compatibility with the host equipment’s QSFP interface and firmware, and check optical power budgets when integrating into existing networks. For best results in critical links, validate link margin with an optical power meter and inspect connectors before deployment.
