Imikhiqizo
I-Optical Fiber
Isingeniso Somkhiqizo
I-Optical Fiber yakhiwe ngengilazi noma izintambo zepulasitiki ezidlulisa idatha njengama-pulses okukhanya, enikeza isivinini sokudlulisa idatha esiphezulu kakhulu. Ingathwala isamba esikhulu solwazi emabangeni amade ngokulahleka kwesignali okuncane. Ngokungafani nezintambo zethusi zendabuko, i-Optical Fiber ayikwazi ukuphazanyiswa yi-electromagnetic kanye nokuphazamiseka kwe-radiofrequency, iqinisekisa isignali ehlanzekile nethembekile. Le khwalithi yenza i-Optical Fiber ukukhetha okuhle kwezokuxhumana kanye namanethiwekhi amade.
Sihlinzeka ngemikhiqizo ehlukahlukene ye-fiber optical, okuhlanganisa i-G.652.D, G.657.A1, G.657.A2, neminye eminingi ukuze ibhekelele izidingo zakho ezithile.
izici
I-fiber optical esiyinikezile inezici ezilandelayo:
1) Ukukhetha okuguquguqukayo kwezingubo ezihlukahlukene ukuze kuhlangatshezwane nezidingo zezikhathi ezahlukene zokufaka isicelo.
I-2) I-polarization yemodi encane yokusabalalisa i-coefficient, ifanele ukudluliswa kwesivinini esikhulu.
3) Superior ashukumisayo ukumelana nokukhathala, kulungele ukusetshenziswa ezindaweni ezahlukene.
Isicelo
Ikakhulu isetshenziswa ezinhlotsheni ezahlukene zekhebula le-optical ukudlala indima yokuxhumana.

Ukupakisha
I-G.652D i-optical fiber ithathwa ku-plastic spool, ifakwe ekhathoni, bese ipakishwa kuphalethi futhi ihlanganiswe nefilimu yokugoqa.
Ama-spools epulasitiki atholakala ngamasayizi amathathu.
1) 25.2km/spool
2) 48.6km/spool
3) 50.4km/spool
Isitoreji
