CableFree FSO Alignment Module

CableFree FSO Alignment Modules are used to ensure optimum alignment and rapid installation of FSO links. Installers use the Alignment Modules during the alignment process to talk to colleague at the remote end of the link and to convert local and remote RSSI into audible beeps. The Alignment module generates the FM audio signal from the microphone and controls whether the FM audio or Data is transferred from the local head over the laser link to the remote laser head. It also displays link statistics (both local and remote) including firmware versions of the laser head and the alignment module. The higher the pitch and the higher the frequency of tones the stronger the RSSI at the local head. The local RSSI tones are NOT heard through the headphones at the local end. The tones that can be heard through the headphones are generated at the remote end. The alignment module is used to set the optical output power of the laser either automatically or manually using the Automatic Transmit Power Control feature.
