A new adaptor for use with the Yokogawa AQ6370 Series of optical spectrum analysers (OSAs) is designed to enhance the sensitivity, dynamic range and level stability by reducing the divergence of light emitted from the input fibre and increasing the input signal to the OSA by 5dB.
Using the new fibre NA adaptor on a GI50/125 multi-mode fibre results in the fibre’s numerical aperture (NA) value being divided by two. The reduction in divergence of the optical input increases the monochromator optical throughput, producing a 5dB (factor 3) increase in signal strength, offering better dynamic range in passive component testing and better level stability in active device testing.
Covering the wavelength range from 350 to 2400nm and applicable to both single-mode and multimode fibres, the AQ6370 Series provides high wavelength accuracy of ±0.01nm, high wavelength resolution of 0.02nm, ultra-high dynamic range of 78dB (typical), wide level range of -90dBm and sweep speed of 0.2s/100nm.
