Wholesale Price of Tunable Optical Module QSFP

Tunable QSFP optical modules typically range from $400 to $1,200 per unit in wholesale quantities, depending on speed, reach, and vendor.

Overview of Tunable QSFP Modules

Tunable QSFP modules are high-speed optical transceivers that allow the wavelength to be adjusted for flexible deployment in dense wavelength-division multiplexing (DWDM) networks. They are widely used in data centers, enterprise networks, and high-performance computing clusters to optimize bandwidth and reduce inventory costs by supporting multiple channels with a single module.

Factors Affecting Wholesale Pricing

1. Data Rate and Type: QSFP modules come in 40G, 100G, 200G, and 400G variants. Tunable modules for higher speeds (100G+ or QSFP28/QSFP-DD) are more expensive than standard 40G QSFP+ modules .
2. Transmission Distance: Modules supporting short-reach (SR) for multimode fiber are cheaper, while long-reach (LR/ER/ZR) single-mode tunable modules for distances up to 80 km or more cost significantly more .
3. Vendor and Compatibility: OEM-branded modules (Cisco, Juniper, Arista) are priced higher, whereas third-party or MSA-compliant modules from wholesale suppliers like FS, Unitekfiber, or QSFPTEK are more cost-effective .
4. Features: Tunable modules with digital diagnostics monitoring (DDM), low latency, and high reliability are priced higher than basic modules .

Typical Wholesale Price Ranges

• 40G QSFP+ Tunable Modules: $400–$700 per unit
• 100G QSFP28 Tunable Modules: $700–$1,000 per unit
• 200G/400G QSFP-DD Tunable Modules: $1,000–$1,200+ per unit Bulk orders often include factory burn-in testing, OEM labeling, and global shipping, which can slightly affect the per-unit cost .

Purchasing Tips

• Verify vendor compatibility with your existing network hardware to ensure plug-and-play operation.
• Consider transmission distance and fiber type (MMF vs SMF) to select the appropriate tunable module.
• Request volume discounts from wholesalers, as prices can drop significantly for orders of 50–100+ units.
• Check for warranty and support, especially for tunable modules used in mission-critical environments . In summary, while exact wholesale prices vary by vendor, speed, and reach, expect tunable QSFP modules to cost several hundred dollars per unit, with higher-speed and long-reach modules at the upper end of the range.
