Really, on selected sorts of switches it DOES make a difference. While a basic-vanilla switch ought to supply you with the expectation that all ports do the job the exact same, Here i will discuss two other circumstances:
Through a procedure called full inner reflection, gentle rays beamed in the fiber can propagate in the core for great distances with remarkably very little บริษัท รังรอง จำกัด attenuation, or reduction in intensity. The diploma of attenuation above distance may differ in accordance with the wavelength of The sunshine and also to the composition on the fiber.
A semiconductor laser emits light via stimulated emission instead of spontaneous emission, which results in significant output electrical รังรอง power (~a hundred mW) and also other benefits linked to the nature of coherent light-weight. The output of the laser is pretty directional, permitting substantial coupling efficiency (~fifty%) into solitary-method fiber.
These kind of switches are generally Utilized in massive networks acquiring complicated architecture. They offer far better protection degrees and precision Regulate but They are really extra pricey than Unmanaged switches.
