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

The BlueOptics BO25K13630D is a QSFP form-factor 40GBASE-ER4L optical transceiver operating at 1310 nm, engineered for long-reach optical links up to 30 km. It aggregates four 10 Gbit/s lanes into a single QSFP module, enabling compact high-density connectivity for data centers, metro networks and fiber backbone installations. The module is intended for use with QSFP ports and supports standard 40GBASE-ER4L transmission characteristics for reliable high-speed transport over single-mode fiber.

Advantages

This QSFP transceiver provides four-lane 10 Gbit/s aggregation in a single compact package, reducing port density and cabling complexity. With a 1310 nm wavelength design and support for links up to 30 km, it offers extended reach suitable for metro and campus backbones while maintaining QSFP compatibility for straightforward integration. The module’s optical characteristics are tailored for long-reach single-mode fiber environments, helping to maintain signal integrity across extended distances.

Suitable for

• Long-reach 40 Gbit/s uplinks between data centers or campus sites
• Metro network aggregation and backbone connections
• High-density QSFP port deployments in switches and routers
• Fiber backbone links requiring 30 km single-mode transmission

Key specifications

• Data rate: 40 Gbit/s aggregated (4 × 10 Gbit/s lanes)
• Wavelength: 1310 nm
• Maximum transmission distance: up to 30 km over single-mode fiber
• Application: 40GBASE-ER4L long-reach Ethernet

How to use

Install the transceiver into a compatible QSFP port on the network device while the device is powered according to the host equipment instructions. Connect single-mode fiber patch cables to the module’s optical interface, observing proper fiber polarity and using appropriate connectors. Verify link status and module recognition via the switch or router management interface. For best results, ensure fiber connectors are clean before insertion and that the connected equipment supports 40GBASE-ER4L operation at 1310 nm.

Recommendations

Use single-mode fiber with appropriate attenuation margin for distances up to 30 km and maintain clean connectors and proper handling to preserve optical performance. Confirm compatibility with the host device’s QSFP port and review link configuration settings in the network equipment to enable 40GBASE-ER4L operation.
