Uyini Umehluko phakathi kwe-UPC ne-APC Connector?

Sivamise ukuzwa ngezincazelo ezinjengokuthi “LC/UPC multimode duplex fibre optic patch cable”, noma “ST/APC single-mode simplex fibre optic jumper”.Asho ukuthini la magama okuthi UPC nesixhumi se-APC?Uyini umehluko phakathi kwabo?Lesi sihloko singakunikeza izincazelo ezithile.

Ithini Incazelo Ye-UPC ne-APC?

Njengoba sazi, amaqoqo ekhebula le-fiber optic ikakhulukazi anezixhumi nezintambo, ngakho-ke igama lokuhlanganisa ikhebula le-fiber lihlobene negama lesixhumi.Sibiza ikhebula le-LC fibre patch cable, ngoba le ntambo inesixhumi se-LC fibre optic.Lapha amagama athi UPC kanye ne-APC ahlobene kuphela nezixhumi ze-fiber optic futhi awahlanganise lutho nezintambo ze-fiber optic.

Noma kunini lapho isixhumi sifakiwe ekugcineni kwefayibha, ukulahlekelwa kwenzeka.Okunye kwalokhu kulahleka kokukhanya kubonakala ngokuqondile emuva kwefayibha emthonjeni wokukhanya okukhiqizile.Lokhu kuboniswa emuva kuzolimaza imithombo yokukhanya kwe-laser futhi kuphinde kuphazamise isignali edlulisiwe.Ukuze sinciphise ukubonakaliswa okungemuva, singakwazi ukupholisha izinsimbi zokuxhuma zibe sekupheleni okuhlukile.Kunezinhlobo ezine zesitayela sokupholisha isixhumi se-ferrule sezizonke.I-UPC ne-APC yizinhlobo ezimbili zazo.Phakathi kwe-UPC imele ukuthi I-Ultra Physical Contact kanti i-APC imfushane ngo-Angled Physical Contact.

Umehluko Phakathi kwe-UPC ne-APC Connector

Umehluko omkhulu phakathi kwe-UPC nesixhumi se-APC wubuso bokuphela kwefayibha.Izixhumi ze-UPC zipholishwa ngaphandle kwe-engeli, kodwa izixhumi ze-APC zifaka ubuso bokuphela kwefayibha obupholishwe nge-engeli engu-8-degree.Ngezixhumi ze-UPC, noma yikuphi ukukhanya okubonisiwe kuboniswa ngokuqondile kumthombo wokukhanya.Kodwa-ke, ubuso obunama-engeli wesixhumi se-APC bubangela ukukhanya okubonisiwe ukuthi kubonakale nge-engeli ekuhlanganiseni kubhekane ngqo emuva kumthombo.Lokhu kubangela umehluko othile ekulahlekelweni kwembuyiselo.Ngakho-ke, isixhumi se-UPC ngokuvamile sidingeka ukuthi okungenani sibe nokulahlekelwa kokubuyisela okungu--50dB noma ngaphezulu, kuyilapho ukulahlekelwa kokubuyisela kwesixhumi se-APC kufanele kube -60dB noma ngaphezulu.Ngokuvamile, ukuphakama kokulahlekelwa kwembuyiselo kwenza kube ngcono ukusebenza kokuhlangana kwezixhumi ezimbili.Ngaphandle kobuso bokuphela kwefiber, omunye umehluko osobala umbala.Ngokuvamile, izixhumi ze-UPC ziluhlaza okwesibhakabhaka kuyilapho izixhumi ze-APC ziluhlaza.

Ukucatshangelwa Kokusebenza Kwezixhumi ze-UPC ne-APC

Akungabazeki ukuthi ukusebenza kokubona kwezixhumi ze-APC kungcono kunezixhumi ze-UPC.Emakethe yamanje, izixhumi ze-APC zisetshenziswa kakhulu kuzinhlelo zokusebenza ezifana ne-FTTx, i-passive optical network (PON) kanye ne-wavelength-division multiplexing (WDM) ezwela kakhulu ekubuyiseleni ukulahlekelwa.Kodwa ngaphandle kokusebenza kwe-optical, izindleko nobulula nakho kufanele kucatshangelwe.Ngakho-ke kunzima ukusho ukuthi isixhumi esisodwa sishaya esinye.Eqinisweni, ukuthi ukhetha i-UPC noma i-APC kuzoncika esidingweni sakho esithile.Ngalezo zinhlelo zokusebenza ezidinga ukunemba okuphezulu kokusayina i-fiber optical, i-APC kufanele kube eyokuqala ukucatshangelwa, kodwa amasistimu edijithali angazwela kakhulu azosebenza kahle ngokulinganayo kusetshenziswa i-UPC.
