We re doing it in just days. So, a lot of our customers find that almost more important than the capital expenditures benefit. Laser technology, however, does have its limitations. Weather is one. It s fog that s a problem.
Fog can act like a brick wall to lasers.
That s because the moisture particles are so small and dense that they act like millions and millions of tiny prisms. When a band of light like a laser tries to blast through, the signal gets distorted and dissipates. The problem is exacerbated as the light beam fades and spreads out over long distances. Cranking up the power to cut through the fog poses safety issues. To counteract the fog factor, meshed topology proponents shorten laser links from a maximum of 500 meters to the 200-meter range.
