The Laser Trigger Module internally mounted photodiode to pick up a weak reflection from the outgoing laser beam. The optical signal is then preamplified, discriminated and ampli-fied so that it can drive a Licel Rack8-3U, a trigger generator or individual transient recorders. This document describes how the optical triggers are trained, presents the principles of the training, and gives some practical advice. In both models, there is a light receiver. Depending on the model, the receiver looks at either just the. As an important part of fiber-optic communication, an optical module is a photoelectric converter which converts electrical signals into optical signals and vice versa. An optical module works at the physical layer of the OSI model and is one of the core components in the fiber communication. The ceramic disc facilitates an easy way of triggering by using optical fibers to avoid insulation problems between the load and trigger units. This disc increases reliability by reducing high voltage electronic components.
