^^Aha, evo baš čitam:
Citat:
Cable Attenuation
Cable attenuation changes with temperature cycling. This change is
typically much more pronounced with tight buffer cables than it is with loose
tube constructions. The reason is that 900micron tight buffer thermoplastic
materials have a thermal expansion coefficient approximately 100 times
greater than that of the silica based optical fiber to which the plastic is
physically bonded. This bond strength varies from cabler to cabler but a
sufficient bond is necessary nonetheless to ensure no “pistoning” of the fiber
to buffer occurs. Basically, the plastic buffer materials expand and contract
at considerably greater rates than the optical fiber thereby exerting stresses
on the fiber, which is manifested in, increased attenuation or in extreme
cases fiber breaks. This is the prime reason for which tight buffer fiber
cables are not ideal for outdoor installation.
Dakle, ko priča o vlaknu, kad ja pričam o celom kablu ulepljenom za onaj hladnostežući asfalt, koji je krt btw.

optika je sjajna stvar, ako si firma koja već ima prokopanu kanalizaciju na sve strane, kao Telekonj naprimer; pa samo menjaš žičke za najlon za pecanje - ovako, videćemo šta će da se desi kad pukne neka cev ispod trotoara naprimer. Ili u sezoni oranja, drljanja i tanjiranja ;)
Kad, tokom pravljenja Nes kafe, umesto da uzmeš mleko iz friza tamo ustvari staviš Nes konzervu - shvatiš koliko je multitasking za*ebana i pipava rabota :)
