2.1. System parts
RECEIVER TRANSMITTER
The complete GD1 system consists of a TX sending a laser beam to the RX. Communication
to control room and power to the GD1 is connected to the TX. Between the TX and RX
there is a cable with communication and power.
The TX where the laser is located sends a diffused light beam (invisible) to the receiver. The
beam is shaped as a cone, not a focused laser beam as you might expect from a laser
pointer. The TX comes complete with the TX and junction box mounted on a backing plate.
The RX has a larger optical aperture to collect the transmitted light and add margin to path
alignment. The TX and RX communicate on a data link (cable). The RX comes complete with
the RX and junction box mounted on a backing plate.
