400G Active Optical Devices in the Philippines include QSFP-DD AOCs, pluggable coherent optics, and high-power 400G transceivers for data center and metro networks.

QSFP-DD Active Optical Cables (AOCs)

QSFP-DD to 4×100G QSFP56 AOCs are high-density breakout solutions that split a single 400G link into four 100G channels, ideal for maximizing port density in data centers. These cables comply with IEEE 802.3cd, QSFP-DD MSA, and SFF-8679 standards, supporting high-throughput connectivity between switches or from switches to GPU nodes in HPC clusters. They are cost-effective alternatives to multiple short-reach transceivers and are suitable for short-reach, high-speed interconnects .

Pluggable Coherent Optics

Nokia's PSE 100G/400G pluggable coherent optics and ICE-X 400G transceivers provide flexible, long-reach solutions for metro, access, and edge networks. These modules support multiple baud rates and modulation formats (QPSK, 8QAM, 16QAM), enabling operation at 100G, 200G, 300G, and 400G over a single wavelength. They are compatible with QSFP-DD form factors and support OIF 400ZR and OpenZR+ standards, offering unamplified reach up to 40km and amplified multi-span operation up to 300km. These devices are optimized for data center interconnects, business services, and broadband backhaul .

Cisco 400G QSFP-DD Modules

Cisco offers High-Power (Bright) 400G QSFP-DD modules and breakout cables. The high-power variants integrate mini optical amplifiers (Mini-EDFA) within the QSFP-DD form factor, supporting DP-mQAM coherent signaling over C-band fiber. Cisco modules support Ethernet and OTN clients, with enhanced Tx optical power (+1dBm) for longer reach. Breakout options include QSFP-DD to 4×100G QSFP56 and QSFP-DD to QSFP-DD copper or AOC cables, suitable for intra-rack or adjacent-rack connections. Passive copper and AOC cables are available in lengths from 0.5m to 3m, providing flexible deployment for high-bandwidth 400G links .

Key Considerations for Deployment in the Philippines

• Form Factor: QSFP-DD is the standard for 400G modules, ensuring compatibility with modern switches and routers.
• Reach: Short-reach AOCs are ideal for intra-data center links, while coherent pluggables support metro and regional distances.
• Power and Cooling: High-power modules may require additional cooling; low-power coherent optics (<6W) are suitable for dense deployments.
• Interoperability: Ensure modules comply with OIF 400ZR, OpenZR+, or IEEE standards for multi-vendor compatibility.
• Use Cases: Data center interconnects, HPC clusters, metro aggregation, and broadband backhaul.

These 400G AODs provide scalable, high-speed connectivity for Philippine enterprises and service providers, enabling efficient network expansion and future-proofing for high-bandwidth applications.
