Price of Coherent Optical Modules QSFP

Coherent QSFP modules range from under $2,000 for short-reach 400G modules to over $130,000 for long-haul 400G/800G ZR+ modules, depending on type, reach, and vendor. 400G QSFP ModulesShort-Reach (SR8): Typically used for in-rack or cross-row connections, these modules cost $1,400–$1,800 from reputable third-party vendors, making them the most economical entry point for 400G deployment.

Medium-

Reach (DR4/FR4): Designed for inter-row or campus links, prices are higher than SR8 but still significantly lower than long-haul coherent optics.

Long-

Haul Coherent (ZR/ZR+): For data center interconnects or metro/regional networks, OEM modules can exceed $130,000, while third-party alternatives may offer substantial savings. 800G QSFP ModulesEarly 800G Modules: Pricing is still stabilizing. Buyers can expect to pay 60–70% of OEM list prices for proven third-party 800G transceivers.

Applications: 800ZR modules support up to 120 km over DWDM links, while 800G ZR+ modules can extend beyond 1,000 km, suitable for metro and regional interconnects. Market ConsiderationsOEM vs Third-Party: OEM modules are often preferred for critical production workloads due to firmware and DOM compatibility, while third-party modules offer cost savings for less critical deployments. Total Cost of Ownership (TCO): Beyond the module itself, deployment costs include cabling (DACs or AOCs) and infrastructure.

For example, a $120 DAC can replace a pair of $1,400 SR8 modules for short in-rack connections, yielding significant savings. Market Trends: The QSFP optical module market is projected to reach $25 billion by 2033, driven by cloud adoption, 5G, and data center upgrades. Key players include Coherent Corp, Lumentum, Cisco, and Broadcom.

SummaryEntry-Level 400G SR8: $1,400–$1,800 (third-party)Medium-Reach 400G DR4/FR4: Higher than SR8, varies by vendorLong-Haul 400G/800G ZR/ZR+: $130,000+ (OEM), lower for third-party800G QSFP-DD: 60–70% of OEM list prices for third-party modules Pricing depends heavily on module type, transmission distance, vendor, and deployment requirements, so careful planning and benchmarking are essential for cost-effective procurement.
