Analog Digital Converter to optical fiber

[Alligator2025]

On an Agilent SEC system hooked up with older components, we use several ADC units to convert analog to optical fiber, which is then send to a data collection. The ADC, >15 years old, has failed, unfortunately.. are there any hints on where used parts like this may be found? The alternative is quite expensive..

Please, photos to the studio.

Seem like Analog->Optic->Whatever is quite simplified data path.

Please clarify:
SEC Detector (principle?) -> analog connection (where?,voltage or current range?) -> ADC (channels?,resolution?) -> optical connector (type?) -> data system (name?,version?)
