How much does a 400g silicon photonics module cost
The price of a 400G silicon photonics module typically ranges from $3,000 to $6,000 per unit, depending on vendor, specifications, and volume.Market ContextThe global market for 400G silicon photonics modules was valued at approximately $428 million in 2024 and is projected to grow rapidly due to increasing demand for high-speed data transmission in data centers and telecommunications networks . Technological advancements, such as integration of DSP chips, 3D packaging, and co-packaged optics, are improving performance while gradually reducing costs .Factors Affecting PriceModule Type and Form Factor: QSFP-DD, OSFP, and QSFP112 modules have slightly different costs due to packaging and lane configurations .Transmission Distance: Modules supporting longer distances (e.g., 500m SMF) generally cost more than shorter-range modules .Vendor and Brand: Leading vendors like Intel, Cisco, Lumentum, and Mellanox may charge premium prices due to reliability, support, and integration with existing infrastructure .Volume and Procurement: Bulk purchases for hyperscale data centers can reduce per-unit cost, while single-unit purchases from distributors may be at the higher end of the range.Example Products400G QSFP-DD DR4: Supports 500m SMF, integrates silicon photonics chips with 7nm DSP, suitable for 400GBASE data centers .400G OSFP Transceivers: Cost-effective, low-power modules for 400G Ethernet links over 500 meters, optimized for AI and high-speed data center applications .QSFP112 400G DR4: Hot-pluggable, supports 500m SMF, compliant with IEEE 802.3bs and QSFP112 MSA standards .SummaryWhile exact pricing varies by vendor, module type, and purchase volume, most 400G silicon photonics modules are priced between $3,000 and $6,000 per unit. For large-scale deployments, contacting vendors directly can provide volume discounts and more precise pricing tailored to specific technical requirements.
