The advantages of fiber optic cable are numerous:  power, reach, speed, durability, reliability and security. These advantages mean they enable the transition to fully digitalized cities, businesses and homes, creating a more sustainable and circular way of life. Here’s a look at fiber optic advantages in detail:

Knowing what is a fiber optic internet network helps to understand their advantages over copper cable internet. The optical fibers deliver more bandwidth since they transmit data through light, which means they can carry signals at higher speeds and with far less distortion than copper cables of the same diameter.

Fiber opticinternet

One optical fiber can carry 90,000 television channels and three million voice calls. Data can fly through fiber optic networks, which can also transmit light over very long distances. These fiber optic advantages mean there could be no modern, high speed internet without optical fiber. That’s why cities and governments are gradually replacing copper cable networks with fiber optic cable.

World-class Nikon objectives, including renowned CFI60 infinity optics, deliver brilliant images of breathtaking sharpness and clarity, from ultra-low to the highest magnifications.

At high numerical apertures of the microscope, depth of field is determined primarily by wave optics, while at lower numerical apertures, the geometrical optical circle of confusion dominates the phenomenon. Using a variety of different criteria for determining when the image becomes unacceptably sharp, several authors have proposed different formulas to describe the depth of field in a microscope. The total depth of field is given by the sum of the wave and geometrical optical depths of fields as:

To operate the tutorial, first select the appropriate objective from the Choose an Objective pull-down menu. The list covers all of Nikon's current objectives in the achromat, plan achromat, plan fluorite, and plan apochromat series. Several specialized objectives are included as well. Next, use the Choose e slider to vary the smallest distance (between a value of 4 and 24 microns) that can be resolved by a detector that is placed in the image plane of the microscope objective.

Where d(tot) represents the depth of field, l is the wavelength of illuminating light, n is the refractive index of the medium (usually air (1.000) or immersion oil (1.515)) between the coverslip and the objective front lens element, and NA equals the objective numerical aperture. The variable e is the smallest distance that can be resolved by a detector that is placed in the image plane of the microscope objective, whose lateral magnification is M. Using this equation, depth of field (d(tot)) and wavelength (l) must be expressed in similar units. For example, if d(tot) is to be calculated in micrometers, l must also be formulated in micrometers (700 nanometer red light is entered into the equation as 0.7 micrometers). Notice that the diffraction-limited depth of field (the first term in the equation) shrinks inversely with the square of the numerical aperture, while the lateral limit of resolution is reduced in a manner that is inversely proportional to the first power of the numerical aperture. Thus, the axial resolution and thickness of optical sections that can be attained are affected by the system numerical aperture much more so than is the lateral resolution of the microscope.
