- Connector Type: Duplex LC
- Wavelengths: 832–918 nm (bidirectional operation)
- Fiber Type: Multimode Fiber (MMF)
- Maximum Data Rate: 40 Gbps
- Transmission Distance: Up to 100 m (OM3), 150 m (OM4/OM5)
- Power Consumption: Approximately 3.5W
- Operating Temperature: 0°C to 70°C
- Compliance: IEEE 802.3ba, QSFP+ MSA (SFF-8436), RoHS
- Weight: Approximately 75 grams (0.165 lbs)
- Digital Diagnostics Monitoring (DDM): Supported for real-time parameter monitoring
The QSFP-40G-SR-BD is ideal for data center interconnects and enterprise backbone upgrades, offering a cost-effective and efficient 40G Ethernet solution. Its ability to reuse existing 10G MMF cabling makes it perfect for high-speed deployments with minimal infrastructure changes.
