Adjustable optical attenuator

basic information

**Functions and Features** - Wide wavelength range, wide attenuation range - High attenuation accuracy, low insertion loss - Absolute and relative attenuation modes - Shutter and zero attenuation function ★ Wide wavelength range, wide attenuation range The 6383A/B can perform attenuation from 0dB to 65dB for any optical signal within the wavelength range of 1200nm to 1650nm. There is no need to shift the entire attenuation range, and power jumps do not occur. ★ High attenuation accuracy, low insertion loss The 6383A/B features high attenuation accuracy of up to ±0.1dB/±0.15dB, reproducibility of ±0.01dB/±0.015dB, and low insertion loss of less than 1.5dB, providing customers with high-precision attenuation. ★ Absolute and relative attenuation modes This device has absolute (including insertion loss) and relative (compared to another set reference value) attenuation modes to meet various customer needs. ★ Light gate and zero attenuation function The shutter completely blocks the output port from the input port, achieving maximum attenuation of optical power. The zero function allows for easy execution of 0dB attenuation with a single key.
