Price list for remote monitoring optical transceiver modules for data center interconnection

Optical transceiver modules for DCI range from approximately $200 for 100G QSFP28 modules to over $3,000 for 800G OSFP modules, depending on speed, form factor, and vendor.Overview of DCI Optical TransceiversData center interconnect (DCI) relies on high-speed optical transceivers to connect servers, storage, and switches across multiple sites. Common form factors include:SFP28: 100G modules, widely used for short- and medium-range DCI links QSFP-DD / QSFP56: 200G–400G modules, supporting high-density deployments OSFP: 400G–800G modules, optimized for AI/ML clusters and hyperscale networks Modules support remote monitoring via Digital Diagnostics Monitoring (DDM), allowing real-time tracking of temperature, voltage, and optical power.Indicative PricingBased on current market offerings:100G QSFP28: $200–$500 per module, depending on vendor and reach (short-range SR, long-range LR) 200G QSFP-DD / QSFP56: $800–$1,500 per module, with options for PAM4 signaling and BiDi configurations 400G QSFP-DD: $1,500–$2,500 per module, often used in spine-leaf architectures for high-density data centers 800G OSFP: $2,500–$3,500+, early deployment modules for AI/ML clusters and hyperscale DCI Prices vary based on vendor, reach, wavelength, and supply chain conditions. Bulk purchases for hyperscale deployments may reduce per-unit cost, but operational costs such as cooling and power draw significantly affect total cost of ownership .Key ConsiderationsThermal Management: High-speed modules (400G–800G) generate significant heat; proper CRAC or liquid cooling is required .Compatibility: Ensure modules are MSA-compliant and compatible with existing switches and routers .Fiber Utilization: BiDi and single-lambda PAM4 modules reduce fiber count and cabling costs .Market Trends: Silicon Photonics (SiPh) modules are expected to dominate future deployments due to lower unit costs and higher efficiency .Vendors and SourcesDigiKey: Offers a wide selection of SFP, QSFP, and CFP modules with pricing and same-day shipping .NADDOD: Provides 100G, 400G, and 800G DCI transceivers with remote monitoring capabilities .Accio: Lists top-rated optical transceivers for data center switches, including QSFP-DD and OSFP modules .Unitekfiber: Supplies MSA-compliant modules with low latency and high reliability for enterprise and hyperscale data centers . For precise pricing, it is recommended to request quotes from multiple vendors, as costs fluctuate with supply chain conditions, module speed, and form factor.
