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

BlueOptics QSFP Transceiver BO25K13630D 40GBASE-ER4L 30 km is a QSFP form-factor optical module engineered for long-reach 40 Gbps Ethernet links over single-mode fiber. The module supports 40GBASE-ER4L transmission up to 30 km, enabling multi-channel 40G connectivity for data center interconnects, metropolitan networks and enterprise backbone links. It is designed for hot-plug installation in compatible QSFP ports and to operate within standard optical and electrical interface parameters required for 40G Ethernet.

Advantages

The transceiver provides stable 40 Gbps throughput with four-channel 10 G lanes aggregated into a single QSFP package, minimizing port density while preserving high bandwidth. Its single-mode fiber optical design and 30 km reach reduce the need for intermediate equipment in long-distance links. The QSFP hot-pluggable form factor allows tool-free replacement or upgrade with minimal service interruption, and the module complies with common electrical and optical signalling conventions used in modern switches and routers.

Suitable for

• Data center interconnects requiring 40 Gbps links between sites up to 30 km apart
• Metro and regional network backbone connections
• Enterprise core and aggregation links needing high-density 40G ports
• Service provider infrastructure supporting multi-channel 40G transport

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Standard: 40GBASE-ER4L
• Data rate: 40 Gbps aggregate (four 10 G channels)
• Optical fiber type: Single-mode fiber (SMF)
• Maximum reach: up to 30 km over SMF
• Optical interface: multi-channel wavelength-division transmission
• Installation: hot-pluggable module

How to use

Install the BlueOptics QSFP transceiver into an empty QSFP port on a compatible switch or router until it clicks into place. Connect single-mode fiber cables with appropriate connectors to the module’s optical ports, ensuring correct fiber polarity and that connectors are clean. Verify link status and performance via the host device management interface and, if available, read optical diagnostics for power and temperature. For removal, power down or disable the port according to equipment guidelines if required, then gently pull the module from the port using the release latch.

Recommendations

Use certified single-mode fiber and maintain connector cleanliness to ensure link quality. Match the module’s reach and optical characteristics to the link budget of your network design. Ensure the host device supports QSFP 40GBASE-ER4L modules and consult the equipment vendor’s compatibility list if needed.
