MINT & WTMINT

WT-MINT with ER attenuation option

10 – IL attenuation option

IL attenuation enables to increase the IL on each output individually. This can be done thanks to a

micrometer head. The attenuation can be total (no power exits from the output) and adjusted with an

accuracy of 0.1dB.

11 – Tunable coupling option

This option is available for PM MINT or PM WT-MINT only. It enables to adjust the splitting ratio of the

interferometer (which is 50/50 for standard interferometers) from 100/0 to 0/100. This can be very useful if

a precise 50/50 ratio is needed.
