Optický QSFP transceiver BlueOptics BO25K13630D 40GBASE-ER4L 1310 nm 30 km

BlueOptics BO25K13630D is an optical QSFP transceiver module that supports 40GBASE-ER4L transmission at a center wavelength of 1310 nm and provides a link reach of up to 30 km over single-mode fiber. The module is hot-pluggable and conforms to industry-standard QSFP form factor and pinout, enabling easy installation in compatible 40 Gbps ports. It is intended for long-reach aggregation and transport where consistent 40 Gbps connectivity is required between switches, routers or optical equipment.

Advantages

The transceiver delivers 40 Gbps aggregate bandwidth across four lanes with low power consumption and stable optical performance for long-reach links. Its QSFP hot-pluggable design simplifies field replacement and upgrades without powering down equipment. Built for single-mode fiber, the module supports extended reach up to 30 km, making it suitable for metro and carrier links as well as data centre interconnects. The device follows common QSFP mechanical and electrical specifications for broad compatibility with networking hardware.

Suitable for

• Long-reach 40 Gbps links between data center sites and aggregation points
• Metro and carrier network transport over single-mode fiber
• Enterprise backbone and campus interconnects requiring 30 km reach
• Upgrading QSFP ports to 40GBASE-ER4L capability

Key specifications

• Data rate: 40 Gbps (aggregate)
• Optical standard: 40GBASE-ER4L
• Wavelength: 1310 nm
• Maximum reach: up to 30 km over single-mode fiber (SMF)
• Form factor: QSFP (quad small form-factor pluggable)
• Connector type: LC (requires appropriate breakout or patching)
• Transmission medium: single-mode optical fiber
• Hot-pluggable design with industry-standard pinout

How to use

Install the module into a compatible QSFP port on network equipment while the system is powered according to vendor guidelines; the hot-pluggable design allows insertion and removal without full system shutdown where supported. Use single-mode fiber cables with appropriate LC terminations and verify link status through the host device management interface. Ensure transceiver optical power budget and fiber attenuation are within required limits for the specified 30 km reach, and perform matching of lane polarity and host port configuration for 40GBASE-ER4L operation.

Recommendations

For reliable operation, inspect fiber connectors for cleanliness before mating, follow manufacturer guidelines for handling and ESD protection, and verify host equipment compatibility with 40GBASE-ER4L QSFP modules. When planning links near the maximum reach, account for splice and connector losses and reserve optical budget margin.
