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

BlueOptics QSFP Transceiver BO25K13630D 40GBASE-ER4L is a 40 Gbps optical module engineered for long-reach single-mode fiber links up to 30 km. The module uses the QSFP form factor to provide four transmit and four receive lanes aggregated to deliver 40Gbps throughput, supporting data center interconnects, metro links and enterprise backbone connections. The transceiver is hot-pluggable and conforms to industry-standard QSFP mechanical and electrical interfaces for compatibility with a wide range of switches and routers.

Advantages

The transceiver offers long-reach performance over single-mode fiber, enabling reliable 30 km links without inline amplification. Its QSFP compact design allows high port density in rack-mounted network equipment while supporting hot-swap replacement to minimize maintenance downtime. The module supports multi-lane optical aggregation for stable 40Gbps throughput and interoperability with standard QSFP sockets, simplifying network upgrades and expansions.

Suitable for

• Data center interconnects between aggregation and core sites
• Metro optical networks requiring 30 km reach
• Enterprise backbone links and campus fiber connections
• High-density switch and router deployments with QSFP ports

Key specifications

• Data rate: 40 Gbps aggregated (QSFP)
• Standard: 40GBASE-ER4L
• Fiber type: Single-mode fiber (SMF)
• Maximum reach: up to 30 km over SMF
• Form factor: QSFP (hot-pluggable)
• Wavelength: multi-lane optics (parallel lanes per 4x10 Gbps)
• Interface: electrical QSFP connector compatible with industry standard hosts

How to use

Install the QSFP transceiver into a compatible QSFP port on a switch or router while the host is powered on or following the vendor-recommended hot-swap procedures. Connect single-mode fiber using appropriate LC or MPO adapters as required by the host equipment and the module's optical breakout or MPO wiring. Verify link status and configuration through the host device management interface and ensure transmit/receive lanes are mapped correctly for 40Gbps operation.

Recommendations

Use quality single-mode fiber with appropriate attenuators if necessary to avoid receiver saturation. Ensure MPO/LC connections are clean and properly secured, and follow equipment vendor guidance for transceiver firmware and compatibility lists. For extended runs approaching 30 km, confirm end-to-end loss budget and consider dispersion and connector loss in planning.
