Which has higher power a laser diode or a VCD
The difference is optical power (as measured with a Laser Power Meter) that is radiated as light, vs. Laser diode has a maximum power P = 5mW. In such a heterostructure of a bipolar interband laser, electrons and holes can recombine, releasing the energy. Laser Diodes and VCSELs are semiconductor lasers, the simplest form of Solid State Lasers. Laser diodes are commonly referred to as edge emitting laser diodes because the laser light is emitted from the edge of the substrate. They operate on the principle of stimulated emission within a tiny crystal structure.

Distance between power communication ADSS optical cable and ground
This paper describes the divergences of ADSS and OPGW cables in detail, underlined by their specific application zones in communication and power areas, their distinguishing features, and added value to compare. Deploying fiber above ground on poles or towers removes the need for underground digging and is particularly useful when the ground is uneven, rocky or both. Fiber in a duct solutions have a major aesthetic. Two primary types are the all-dielectric self-supporting (ADSS) optical cable and the optical ground wire (OPGW) optical cable. Despite their shared objective of transmitting data, these cables diverge significantly in terms of structure, application, and installation methods. But underneath the jacket, they are completely different animals: ADSS (All-Dielectric.
