Manual Adjustable Fiber Delay Line
The third generation manual fiber delay line (Optical fiber delay line) is a unique delay mechanism with high precision and low insertion loss, continuous and reliable operation; a wide delay range can reach an order of ps & fs, high reliability, low polarization related loss (<0.1dB) and low insertion change (<0.5dB, simple and compact structure). It can be customized according to the user needs of the product requirements.

Direction for use:
- Link the optical fiber COM end to the light source, and pay attention to ensure the link adaptation and the clean core end surface
- Please adjust the use within the effective range, and strictly exceed the use range
- It is strictly prohibited to drag optical fiber and small radian curling optical fiber and cause optical fiber damage
- If there is a locking mechanism, you only need to debug the target amount and lock the precision screw on the rocker with the inner hexagonal, that is to lock the target parameters
Container loading list:
