Wholesale 400G optical modulators typically range from $1,500 to $4,000 per unit, depending on type, reach, and supplier. Overview of 400G Optical Modules400G optical modulators, also known as optical transceivers or modules, convert electrical signals into optical signals for high-speed data transmission. Common form factors include QSFP-DD and OSFP, with variants such as DR4, FR4, LR4, and ZR+ supporting different transmission distances and applications.

These modules are widely used in data centers, AI clusters, enterprise networks, and metro networks to meet growing bandwidth demands.

Wholesale Pricing Factors

Form Factor: QSFP-DD modules are backward-compatible with QSFP28, while OSFP modules offer higher thermal efficiency and port density.

OSF

P DR4 modules are increasingly adopted in hyperscale data centers. Transmission Distance: Short-range (SR8) modules cost less than intermediate (DR4/FR4) or long-range (LR4/ER4) modules. For example, a 2 km DR4 module is priced lower than a 120 km ZR+ coherent module.

Modulation Technology: PAM4 modulation and coherent optics (ZR+) increase performance but also raise costs. Supplier and Certification: Factory-direct suppliers like Fiberwdm, Unitekfiber, FiberMall, and ETU-Link offer competitive wholesale pricing, often with OEM-quality assurance and compliance with IEEE 802. 3bs, QSFP-DD MSA, and RoHS standards.

Typical Wholesale Price RangesQSFP-DD DR4 (2 km): Approximately $1,500–$2,500 per unit for bulk orders. QSFP-DD ZR+ Coherent (120 km): Approximately $3,000–$4,000 per unit, reflecting higher performance and longer reach.

OSF

P DR4 modules: Similar to QSFP-DD DR4, with slight premium for thermal and density advantages, typically $1,800–$2,800 per unit.

Purchasing Considerations

Minimum Order Quantity (MOQ): Wholesale suppliers often require bulk orders; verify MOQ before purchase. Compatibility: Ensure modules are compatible with existing switches and routers; many suppliers provide pre-testing and coding for major OEM hardware. Technical Specifications: Confirm wavelength (e.g., 1310 nm for DR4), connector type (MPO-12), and power consumption (e.g., 9.

5W max for DR4) to match network requirements. Supplier Reliability: Choose verified suppliers with ISO 9001, CE, RoHS, and FCC certifications to ensure quality and long-term support. In summary, wholesale 400G optical modulators are available from $1,500 to $4,000 per unit, with pricing influenced by form factor, reach, modulation type, and supplier.

For bulk procurement, contacting suppliers directly for quotes and technical verification is recommended to secure the best pricing and compatibility.
