Papua New Guinea Active Optical Module QSFP-DD

QSFP-DD optical modules enable ultra-high-speed 400G fiber connections with multi-channel full-duplex support, low latency, and advanced monitoring features.

Key Features

Bandwidth and Channels: QSFP-DD modules provide eight independent full-duplex channels, each capable of up to 50 Gbps, resulting in an aggregate bandwidth of 400 Gbps for standard modules like MikroTik's DDQ+85MP01D . Some high-power variants, such as Cisco's 400G QSFP-DD High-Power (Bright), include enhanced Tx optical power for longer reach and coherent signal transmission . Reach and Connectivity: These modules support distances up to 100 meters over MTP/MPO fiber cables for short-reach applications, while high-power or coherent variants can extend reach for data center interconnects, metro, and cloud networks . They typically use MTP/MPO or duplex LC connectors depending on the vendor and application. Monitoring and Diagnostics: QSFP-DD modules include built-in digital diagnostics for optical power, voltage, temperature, and laser bias current, allowing real-time monitoring and proactive maintenance . Cisco modules also support Layer-1 security features, including AES 256-bit encryption for sensitive data transmission . Applications: QSFP-DD modules are ideal for:

• Data center interconnects and high-speed server-to-server links
• Cloud and metro networks
• AI/ML and rack-scale data center expansion using low-latency PCIe Gen 5 optical links
• Wireless backhaul and campus networks requiring high throughput and reliability Power and Efficiency: Modules are designed for low power consumption, typically under 5W for linear pluggable optics, making them suitable for dense deployments .
