Quotation for Passive Optical Network QSFP-DD

QSFP-DD transceivers support 400G to 800G high-speed optical networking, with prices ranging from $1,400 for short-range modules to over $130,000 for long-haul coherent modules.OverviewQSFP-DD (Quad Small Form-Factor Pluggable Double Density) transceivers are designed for high-speed Ethernet and coherent optical networks, doubling the electrical interfaces of standard QSFP modules to achieve 400G and 800G speeds. They are widely used in data centers, metro, and regional networks, supporting both short-range multimode and long-haul coherent DWDM deployments . Key features include:Short-range SR8 modules for in-rack or cross-row connectivity, typically under $2,000 from third-party vendors .Coherent ZR/ZR+ modules for long-haul DCI or metro/regional networks, capable of 120 km to over 1,000 km, with prices exceeding $130,000 for OEM modules .AES-256 encryption for Layer 1 security and OTN compliance for multi-vendor interoperability .Flexible deployment options, including 2x100G connections over single-mode fiber and support for 50GHz-spaced DWDM networks .Pricing ConsiderationsQSFP-DD pricing varies significantly based on module type, reach, and vendor:Entry-level 400G SR8 modules: $1,400–$1,800 for short-range data center use .DR4/FR4 modules: Mid-range options bridging data center rows or campus links.Long-haul coherent ZR/ZR+ modules: $50,000–$130,000 depending on OEM and distance .Volume discounts: Many vendors offer tiered pricing for bulk purchases, which can significantly reduce total cost.Vendor OptionsSmartoptics: Offers cost-efficient 400G/800G QSFP-DD modules for metro, regional, and DCI networks, with both short-range and coherent options .Cisco: Provides QSFP-DD and OSFP 800G ZR/ZR+ coherent optics modules, optimized for high-capacity single-span DCI and metro/regional applications .Third-party suppliers: Pivotal Optics and Planet Fibers provide MSA-compliant, hot-pluggable QSFP-DD modules with flexible connector options and warranty support .Recommendation for a QuoteTo request a quote for a PON deployment using QSFP-DD:Specify network requirements: Data rate (400G or 800G), reach (short-range vs long-haul), and number of ports.Select module type: SR8 for short-range, DR4/FR4 for intermediate, ZR/ZR+ for long-haul.Choose vendor: OEM for guaranteed performance and interoperability, or reputable third-party for cost savings.Request volume pricing: Include expected quantities to obtain tiered discounts. By providing these details to vendors like Smartoptics, Cisco, or Pivotal Optics, you can receive a tailored quote that balances performance, reach, and cost for your passive optical network deployment .
