Network QSFP transceiver BlueOptics BO25K13630D 40GBASE-ER4L 40Gbps 30 km

The BlueOptics BO25K13630D is a QSFP form-factor 40GBASE-ER4L optical transceiver engineered for 40 Gbps aggregate throughput and extended reach of up to 30 km over single-mode fiber. It aggregates four independent 10 G lanes into a single, hot-pluggable QSFP module, enabling straightforward upgrades in data center interconnects and metropolitan area network links. The module supports low-power operation and is designed for compatibility with standard QSFP ports, providing a compact solution for long-reach fiber connections where space and power efficiency are important.

Advantages

The transceiver delivers four-lane 10G signaling in a single 40G QSFP module, reducing the number of modules and ports required for high-capacity links. Extended single-mode reach of up to 30 km allows direct fiber connections between distant sites without the need for intermediate amplification. Hot-pluggable design simplifies maintenance and upgrades, while low power consumption minimizes operational costs and cooling requirements in racks and data center environments.

Suitable for

• Data center interconnects requiring 40 Gbps links over single-mode fiber
• Metro and campus backbone connections up to 30 km
• High-capacity uplinks between aggregation switches and routers
• Redundant long-reach links in enterprise and carrier networks

Key specifications

• Form factor: QSFP (quad small form-factor pluggable)
• Standard: 40GBASE-ER4L
• Aggregate data rate: 40 Gbps (4 × 10 Gbps lanes)
• Maximum reach: up to 30 km over single-mode fiber
• Optical interface: four-lane 10G multiplexed in QSFP
• Fiber type: single-mode fiber (SMF)
• Power: low-power design suitable for rack-mounted systems
• Installation: hot-pluggable for tool-free replacement

How to use

Insert the QSFP transceiver into a compatible QSFP port on a switch, router or optical transponder while the host device is powered according to the vendor’s hot-swap guidelines. Connect the single-mode fiber cable to the module’s optical interface using appropriate connectors and ensure proper end-face cleanliness. Configure the host port to operate at 40G or allow auto-negotiation if supported. Verify link status through the device management interface and monitor for alarms or diagnostic data available via the host platform.

Recommendations

Use single-mode fiber with matching connectors and maintain proper cleaning procedures to preserve signal integrity. Match the module’s 40GBASE-ER4L specifications with the remote transceiver and fiber link budget to ensure reliable operation up to 30 km. Observe ESD precautions during handling and follow the host equipment vendor’s guidelines for firmware and compatibility to avoid interoperability issues.
