Network QSFP Transceiver BlueOptics BO25K13630D 40GBASE-ER4L 30 km

BlueOptics BO25K13630D is a QSFP transceiver module that implements the 40GBASE-ER4L optical standard for long-reach 40 Gbps Ethernet links up to 30 km over single-mode fiber. The compact QSFP form factor supports high-density port deployment and hot-pluggable operation, enabling straightforward integration with compatible switches and routers for data center uplinks, metro interconnections and other long-distance fiber connections.

Advantages

This QSFP transceiver provides stable 40 Gbps throughput with an extended reach of up to 30 km, reducing the need for intermediate optics or regeneration. The module’s QSFP form factor allows four-lane parallel optics in a single hot-swappable package, simplifying installation and saving rack space. Built for interoperability with standard 40GBASE-ER4L interfaces, the transceiver supports reliable link establishment and predictable performance in long-haul and metro environments.

Suitable for

• Data center uplinks between aggregation and core switches
• Metro network links and ring interconnects
• Long-distance fiber connections between campus or facility sites
• High-density switch/router ports requiring 40 Gbps long-reach optics

Key specifications

• Optical standard: 40GBASE-ER4L
• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Maximum link distance: up to 30 km over single-mode fiber
• Data rate: 40 Gbps
• Fiber type: single-mode fiber (SMF)
• Connector interface: appropriate LC duplex/parallel fiber mating (module uses QSFP optical interface)
• Hot-pluggable: yes

How to use

Install the BlueOptics QSFP transceiver into a compatible QSFP port on a switch or router while the host is powered on, observing electrostatic discharge precautions. Connect single-mode fiber using the appropriate mating connectors and ensure correct fiber polarity. After insertion and fiber connection, confirm link status through the host device management interface or LED indicators. If necessary, verify transceiver compatibility and link parameters in the switch/router configuration to ensure operation at 40 Gbps and correct lane mapping.

Recommendations

Store and handle the transceiver in a clean, static-controlled environment. Use certified single-mode fiber cabling for distances up to 30 km and avoid excessive bending or stress on the fiber. Monitor operating temperature and link diagnostics through the host device to detect any signal degradation, and replace the module if persistent link errors occur.
