Price list for QSFP28 tunable optical modules for data center interconnection

QSFP28 modules for 100G data center links typically range from $150 to $600 per module, depending on type, reach, and vendor. Price Ranges by Module TypeSR4 (Short-Range, multimode, up to 100m on OM4 fiber): $150–$250 per module. Ideal for intra-rack or nearby rack connections, offering the most economical solution for short-reach links.

LR4 (Long-Range, single-mode, up to 10 km): $400–$600 per module. Suitable for building-to-building or campus-wide interconnects, using four CWDM wavelengths over duplex LC fiber. CWDM4 (Single-mode, 2 km–2.

5 km): $350–$500 per module. Optimized for medium-range data center interconnects with cost-effective wavelength multiplexing. ZR4 (Extended Reach, single-mode, up to 80 km): $800–$1,200 per module.

Used for long-haul metro or telecom links, less common in standard data centers. Factors Affecting QSFP28 PricingEngineering and Testing Costs: Modules undergo design verification and reliability testing, including temperature cycling, moisture resistance, and shock tests. These costs are reflected in the final price.

Bill of Materials (BOM): Chipsets, optical components, and mechanical casings contribute significantly to cost. Production and Yield: Labor, equipment, and manufacturing yield rates influence module pricing. Vendor and Brand: OEM modules from Cisco, Juniper, or Arista are typically higher priced than third-party vendors like FS, Amphenol, or Cables on Demand.

Purchase Volume: Bulk orders often reduce per-unit cost, while small quantities may carry a premium. Market Strategy: Discounts, promotions, or end-of-quarter pricing can affect module cost. Vendor ExamplesFS.com: Offers 100G QSFP28 modules with 30-day free returns, prices generally in the $200–$500 range depending on type and reach.

Cables on Demand: Provides Amphenol QSFP28 modules in SR and LR variants, with pricing aligned to short- and long-range specifications.
