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

BlueOptics BO25K13630D is a 40GBASE-ER4L QSFP optical transceiver operating at 1310 nm and engineered for single-mode fiber links up to 30 km. The module fits standard QSFP ports and provides four-lane 10 Gbps optical interfaces aggregated to a 40 Gbps electrical QSFP connection. It supports hot-plug installation and is intended for long-haul connections such as backbone links, campus interconnects and metro or WAN segments where single-mode fiber is used.

Advantages

The transceiver offers long-reach performance (up to 30 km) over single-mode fiber with a 1310 nm wavelength and ER4L class optics. Its QSFP form factor consolidates four 10 Gbps lanes into a single 40 Gbps port, reducing port count and simplifying cabling for high-density environments. Hot-plug capability enables replacement or upgrades without shutting down the host system, while compatibility with standard QSFP interfaces ensures straightforward integration into existing network equipment that supports QSFP modules.

Suitable for

• Data center spine-to-leaf or switch-to-switch uplinks requiring 40 Gbps over single-mode fiber
• Campus and inter-building connections across distances up to 30 km
• Service provider or enterprise WAN links that need long-reach 40G connectivity
• Network equipment with QSFP ports where aggregated 4x10G optical lanes are acceptable

Key specifications

• Optical standard: 40GBASE-ER4L
• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Wavelength: 1310 nm
• Maximum reach: up to 30 km over single-mode fiber
• Lane configuration: 4 x 10 Gbps optical lanes aggregated to 40 Gbps
• Connector type: LC (single-mode duplex per lane or MPO depending on breakout)
• Installation: hot-pluggable

How to use

Install the BO25K13630D module into an available QSFP slot on compatible network equipment while the host is powered on if hot-plug capability is supported. Use single-mode fiber patch cords and appropriate LC or MPO adapters as required by the specific breakout or direct-attach configuration. Verify link status and lane aggregation in the switch or transceiver diagnostics; configure the connected interfaces on both ends for 40 Gbps operation and ensure fiber polarity is correct. Follow vendor guidance for any required firmware or compatibility settings on the network device.

Recommendations

To maintain reliable long-reach performance, use ITU-T-compliant single-mode fiber with low attenuation, keep connector end-faces clean, and verify link budgets for 30 km spans including splice and connector losses. Confirm that the host equipment explicitly supports QSFP 40GBASE-ER4L modules and consult the switch vendor for any interoperability notes before deployment.
