What Is High Blood Pressure? Blood pressure is the amount of force exerted by the blood against the walls of the arteries. A person's blood pressure is considered high when the readings are greater than 140 mm Hg systolic (the top number in the blood pressure reading) or 90 mm Hg diastolic (the bottom number).
You are here: Fiber optic light source is a fiber optic test equipment to measure the fiber optic loss for both single mode fiber cable and multimode fiber cables; usually the fiber optic light source is used with the fiber optic power meters.
To put it simply, fibre optics is a technology whereby a signal like video, data or voice, is concentrated on a light beam and sent down a glass tube over large distances, with very little distortion and loss. The principles of fibre optics are simple and easy to understand.here are 3 different types of fibre optics cable available. These are: 1. Step Index. This cable has a distinct index of refraction for the core and the cladding. It is the cheapest type of cable and causes deformation due to the various path lengths of the light ray. This is called modal distortion.
