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

BlueOptics BO25K13630D is a QSFP optical transceiver module designed for 40GBASE-ER4L single-mode fiber links. Operating at 1310 nm, it provides an aggregate data rate of 40 Gbps and is specified for transmission distances up to 30 km. Engineered for long-reach uplinks, aggregation and interconnects in data centres and carrier networks, this transceiver supports reliable high-speed connectivity where extended single-mode fiber reach is required.

Advantages

The transceiver supports quad-lane 10 Gbps modulation to deliver a 40 Gbps aggregate throughput with low latency and stable performance over long distances. It conforms to QSFP form-factor standards for compatibility with a wide range of switches and routers. Its single-mode design and 1310 nm wavelength offer reduced dispersion over extended links up to 30 km, while the module’s compact QSFP package simplifies installation in high-density environments.

Suitable for

• 40G uplinks between aggregation switches in data centres
• Long-reach interconnections in carrier and metro networks
• High-density optical ports requiring QSFP modules
• Migration paths from 10G to 40G backbone links

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Protocol: 40GBASE-ER4L
• Data rate: 40 Gbps aggregate
• Wavelength: 1310 nm
• Maximum reach: up to 30 km over single-mode fiber
• Fiber type: Single-mode fiber (SMF)

How to use

Install the QSFP transceiver into a compatible QSFP port on your switch or router following the host equipment vendor's hot-plug instructions. Connect single-mode fiber patch cords terminated with the appropriate connectors to the module’s optical interface and ensure proper fiber polarity. Verify link status and diagnostics through the host device management interface; monitor optical power and link status after insertion. For safe handling, avoid touching optical interfaces and follow ESD precautions.

Recommendations

Use factory-tested single-mode fiber and connectors rated for long-reach applications; keep transceiver firmware and host device drivers up to date. For links approaching the 30 km specification, verify end-to-end optical budget and consider inline amplification or dispersion management only if explicitly supported by the network design. Store unused modules in protective caps and ESD-safe packaging.
