Netwerk QSFP-transceiver BlueOptics BO25K13630D 40GBASE-ER4L 30 km

The BlueOptics BO25K13630D is a QSFP 40GBASE-ER4L optical transceiver designed for long-reach 40 Gbit/s Ethernet links over single-mode fiber. Intended for QSFP ports, this module delivers 40 G transmission up to 30 km, making it suitable for data center aggregation, metro connectivity and long-distance interconnects between switches and servers. The module implements standard 40GBASE-ER4L interfaces for reliable, high-capacity optical transport in high-density network environments.

Advantages

The transceiver supports 40 Gbit/s aggregated lanes over single-mode fiber for extended distance up to 30 km, providing a compact QSFP form factor that conserves port density. It conforms to common 40GBASE-ER4L optical specifications for interoperability with compatible network equipment and offers low-latency optical transport suitable for core and aggregation layers. The module’s design emphasizes plug-and-play insertion into QSFP ports and stable operation in typical data center and metro ambient conditions.

Suitable for

• Long-reach 40G links between data centers or campus sites
• Core and aggregation switch interconnects in metro networks
• High-density QSFP deployments where port conservation is required
• Server-to-switch or switch-to-switch connections over single-mode fiber

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Data rate: 40 Gbit/s (aggregate)
• Standard: 40GBASE-ER4L
• Fiber type: single-mode optical fiber
• Maximum reach: up to 30 km (single-mode fiber)
• Interface: optical multi-lane QSFP connector

How to use

Install the module into a compatible QSFP port on a switch or router while the host device is powered according to the equipment manufacturer’s hot-plug guidance. Connect single-mode fiber with appropriate LC or MPO/MTP cabling as required by the host and remote transceiver; ensure connectors and transceivers are clean before mating. Verify link negotiation and status via the host device management interface and monitor optical power levels and error counters after installation.

Recommendations

Use high-quality single-mode fiber and maintain proper connector cleanliness to achieve the specified 30 km reach. Confirm compatibility with the host device and verify optical power budget and dispersion for the intended link distance. Avoid bending fiber beyond recommended radii and operate the module within the host-specified temperature and power ranges.
