Optical Attenuator Price Quote

Optical attenuators range from approximately $10 for basic fixed fiber-optic types to several thousand dollars for high-end variable or electronically controlled models.

Price Overview

• Fixed Fiber-Optic Attenuators: Basic single-mode or multimode fixed attenuators with standard connectors (LC, SC, FC, ST) typically cost $10–$50 per unit depending on attenuation value and connector type (DigiKey, Thorlabs) .
• Variable Optical Attenuators (VOAs): Manual or electronic VOAs for single-mode or multimode fibers range from $100 to $500 for standard lab-grade units, offering adjustable attenuation from 0–60 dB (FS, Thorlabs) .
• High-End Electrically Controlled VOAs: Advanced models like the Keysight N7752C, which include dual-channel control and integrated optical power meters, can cost several thousand dollars, reflecting their precision, automation, and integration capabilities .

Factors Affecting Price

1. Type of Attenuator: Fixed attenuators are generally cheaper than variable or electronically controlled models.
2. Fiber Type: Single-mode (SM), multimode (MM), or polarization-maintaining (PM) fibers influence cost, with PM and SM electronic VOAs being more expensive.
3. Connector Type: Common connectors include FC/PC, FC/APC, SC, LC, ST, and SMA; specialty connectors may increase price.
4. Attenuation Range: Higher dB ranges or precision-controlled attenuation typically increase cost.
5. Supplier and Quantity: Bulk orders or distributor pricing (DigiKey, FS, Thorlabs) may offer discounts.
