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

The BlueOptics BO25K13630D QSFP transceiver is a 40GBASE-ER4L optical module operating at 1310 nm, designed for long-reach single-mode fiber links with a transmission distance up to 30 km. It fits standard QSFP ports and enables 40 Gbps aggregation and backbone connections in metro, campus and data center interconnects. The module offers pluggable connectivity for compatible switches, routers and media converters and is intended for environments that require stable high-speed optical links over extended distances.

Advantages

The transceiver supports 40GBASE-ER4L transmission over single-mode fiber at 1310 nm, providing a balance of speed and long-reach capability up to 30 km. Its QSFP form factor allows hot-pluggable installation into 40G ports and simplifies upgrades without changing cabling infrastructure. The module is designed for interoperability with standard QSFP interfaces and offers predictable optical performance for aggregation and backbone applications.

Suitable for

• Metro and regional fiber links requiring 40 Gbps capacity
• Campus backbone and building-to-building interconnects over single-mode fiber
• Data center interconnect (DCI) where long-reach links are needed
• Aggregation points and high-speed uplinks for switches and routers
• Media converters and optical multiplexing systems that accept QSFP modules

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Standard: 40GBASE-ER4L
• Wavelength: 1310 nm
• Maximum reach: up to 30 km over single-mode fiber
• Data rate: 40 Gbps aggregate
• Connector type: compatible with single-mode fiber interfaces (QSFP adapter cage)

How to use

Insert the QSFP transceiver into a compatible 40G QSFP port on your switch, router or media converter until it clicks into place. Connect single-mode fiber patch cords to the module ensuring correct transmitter/receiver orientation and secure connectors. Verify link status via device indicators or management interfaces and monitor optical parameters in the host system. For removal, power down or disable the port if required by the host device, then press the module latch and pull the transceiver straight out.

Recommendations

The module is intended for single-mode fiber installations; use appropriate LC/APC or LC/PC patch cords as required by your equipment, observe manufacturer optical budgets and link-loss calculations, and follow ESD precautions during handling. Confirm host device compatibility with QSFP 40GBASE-ER4L modules before deployment to ensure proper link negotiation and optical performance.
