Delving into fiber optics, modulation, and long-haul transmission insights.

Two black DPPSS driver units with a digital display reading 2.004 are placed on a perforated surface. Each device is connected to a small module emitting a green laser beam. The setup includes various switches and indicators on the front panel, and there is a small CivilLaser card in the background displayed upright.

The image features an electronic circuit board placed on a metallic surface with perforated holes. Blue terminal connectors and cylindrical capacitors are visible on the green board. Nearby, an orange fiber optic cable is coiled beside a metal component encased in a transparent cover. The setting appears to be a technical or engineering workspace.
