India Certified Co-packaged Optical QSFP-DD

QSFP-DD (Quad Small Form-factor Pluggable Double Density) modules are high-speed 400G optical transceivers suitable for co-packaged optics, widely available from certified vendors and compatible with Indian deployments. Overview of QSFP-DD ModulesQSFP-DD is a high-density, high-bandwidth optical transceiver standard designed for 400G Ethernet and beyond. It doubles the electrical lanes compared to legacy SFP modules, enabling 8-lane 400G transmission while maintaining a compact form factor, making it ideal for co-packaged optics in data centers and enterprise networks.

QSFP-DD modules support both 400GE and 4x100GE interfaces, providing backward compatibility with previous-generation routers and switches (Cisco).

Key Features

Form Factor: QSFP-DD, compatible with OSFP and QSFP112 in some deployments. Transmission Distance: Options include ZR (up to 120 km) and ZR Plus variants for regional to long-haul distances with multiple amplification sites. Modulation and Baud Rates: Supports QPSK, 8-QAM, and 16-QAM modulation schemes with configurable TX filter shaping for optimized signal quality.

Applications: Data centers, AI workloads, enterprise networks, service provider networks, and high-performance computing. Standards Compliance: Complies with OIF MSA, OpenZR+, and SFF-8679 Rev 1. 8.

Availability in India

While specific India certification is not explicitly listed in the sources, global vendors like Cisco and FS provide QSFP-DD modules that can be shipped to India.

F

S, for example, offers a portfolio of 400G QSFP-DD transceivers with nearby warehouse shipping and 30-day return policies, making them accessible for Indian enterprises. Cisco modules are widely deployed in India through authorized partners and distributors, ensuring compliance with international standards and local network requirements.

Considerations for Co-

Packaged Optics

Integration: QSFP-DD modules can be integrated directly with switch ASICs or line cards, reducing latency and improving power efficiency. Thermal Management: High-density 400G modules require careful cooling and airflow planning in racks. Vendor Certification: Ensure modules are sourced from authorized distributors to guarantee interoperability and warranty support in India.

Conclusion

For Indian deployments, certified QSFP-DD modules from Cisco, FS, and other global vendors provide reliable, high-speed optical connectivity suitable for co-packaged optics. They support 400G Ethernet, long-distance transmission, and multiple modulation schemes, making them ideal for modern data centers and enterprise networks. When procuring, verify vendor certification, standards compliance, and local availability to ensure seamless integration.
