Applications and Product Types

Optical attenuators are used to adjust optical signal strength, prevent receiver saturation, balance power in WDM systems, and perform bit error rate testing. They are available in:

• Fixed Optical Attenuators – Provide a constant attenuation level, often used in CATV systems or short-distance fiber links.
• Variable Optical Attenuators (VOAs) – Allow adjustable attenuation for testing, calibration, or dynamic network management.
• Fiber Types – Single-mode (SM), multimode (MM), and polarization-maintaining (PM) fibers.
• Connector Types – FC/PC, FC/APC, SMA, LC, SC, depending on the application . These companies serve a wide range of industries, including telecommunications, data centers, laboratory research, and high-power laser diagnostics, providing both standard and customized optical attenuator solutions.
