QSFP transceiver BlueOptics BO25K13630D 40GBASE-ER4L 30 km

The BlueOptics BO25K13630D is a hot-pluggable QSFP transceiver designed for 40GBASE-ER4L links with an extended reach of up to 30 km over single-mode fiber. Intended for deployment in data centers, enterprise networks and metro aggregation, this 40 Gbit/s module uses ER4L optics to deliver long-distance 40G connectivity while remaining compatible with switches and routers that accept QSFP form-factor modules. The transceiver supports standard multiplexing and electrical interfaces for seamless integration into high-speed optical infrastructures.

Advantages

The QSFP Transceiver offers a compact QSFP footprint with hot-pluggable convenience, allowing upgrades or replacements without interrupting system operation. ER4L optics provide extended reach up to 30 km on single-mode fiber, enabling long-distance links between sites or within campus and metro networks. With a 40 Gbit/s throughput and interoperability with industry-standard QSFP ports, the module supports high-bandwidth applications and scalable network growth while minimizing the need for additional aggregation hardware.

Suitable for

• 40G interconnects between switches and routers in data centers
• Long-distance 40G links for campus and metro networks
• High-bandwidth uplinks and aggregation ports
• Network upgrades to add 40G capacity without replacing chassis

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Data rate: 40 Gbit/s aggregate
• Optical type: ER4L multimode-compatible optics for extended reach on single-mode fiber
• Maximum reach: up to 30 km over single-mode fiber
• Connector type: duplex/paired single-mode fiber interface (compatible with LC-type duplex patching via breakout where applicable)
• Hot-pluggable: yes, supports insertion/removal without system shutdown

How to use

Install the QSFP transceiver into a compatible QSFP port on a switch or router following the equipment manufacturer’s insertion procedure. Connect single-mode fiber patch cables to the transceiver’s optical interface, ensuring correct transmit/receive orientation and secure LC duplex connections where required. After insertion, verify link status and configuration on the host device and adjust transport settings (transmission power, lanes aggregation or breakout modes) as needed according to your switch or router documentation. For multi-lane operation or breakout to 4x10G, configure the host port to the appropriate mode before traffic is passed.

Recommendations

Use high-quality single-mode fiber and clean connectors to achieve the specified 30 km reach. Verify that the host device supports 40GBASE-ER4L optics and the QSFP form factor; consult the switch/router compatibility list if vendor-specific restrictions apply. For installations approaching the maximum reach, monitor link margin and consider link testing with an optical power meter to confirm adequate performance.
