Isakhiwo esiyisisekelo se-fiber optical ngokuvamile sakhiwe umgodla wangaphandle, ukuvala, umgogodla, nomthombo wokukhanya. I-fiber yemodi eyodwa kanye ne-multi-mode fiber inomehluko olandelayo:
Umehluko wombala we-sheath: Ezisetshenziswa ezingokoqobo, umbala we-sheath wangaphandle wefayibha ungasetshenziswa ukuhlukanisa ngokushesha phakathi kwe-fiber yemodi eyodwa kanye ne-multi-mode fiber. Ngokwencazelo yezinga le-TIA-598C, i-fiber OS1 yemodi eyodwa kanye ne-OS2 zisebenzisa ijakhethi yangaphandle ephuzi, i-fiber enemodi eminingi i-OM1 ne-OM2 ithatha ijakhethi yangaphandle ewolintshi, futhi i-OM3 ne-OM4 zisebenzisa ijakhethi yangaphandle eluhlaza okwesibhakabhaka i-aqua (ngokungasebenzisi kwezempi) .
Umehluko wedayamitha eyinhloko: Ifayibha yemodi eminingi kanye nefayibha yemodi eyodwa inomehluko omkhulu kudayamitha eyinhloko, ububanzi obuyinhloko befayibha yemodi eminingi ngokuvamile bungu-50 noma 62.5µm, futhi ububanzi obuyinhloko befibre yemodi eyodwa ngu-9µm. Uma kubhekwa lo mehluko, i-fiber yemodi eyodwa ingadlulisela kuphela amasignali optical ane-wavelength ye-1310nm noma i-1550nm kububanzi obuncane bomgogodla, kodwa inzuzo yomgogodla omncane ukuthi isignali ye-optical isakazeka ngomugqa oqondile ngendlela eyodwa. i-fiber, ngaphandle kokuphikiswa, ukuhlakazeka okuncane, nomkhawulokudonsa ophezulu; I-multi-mode fiber core ibanzi, futhi ingakwazi ukudlulisa izindlela ezihlukahlukene kubude begagasi obunikeziwe bokusebenza, kodwa ngesikhathi esifanayo, ngenxa yokuthi kunamakhulu ezindlela ezidluliswa ku-multi-mode fiber, i-propagation njalo futhi Izinga leqembu lemodi ngayinye lihlukile, ukuze ububanzi bebhendi bomucu bube buncane, ukuhlakazeka kukhulu, futhi ukulahlekelwa kukhulu.
Ububanzi obujwayelekile bokuvala bemicu eminingi yokubona bungu-125um, kanti ububanzi obujwayelekile bongqimba oluyisivikelo lwangaphandle bungu-245um, obungahlukanisi imodi eyodwa eminingi.
Umehluko womthombo wokukhanya: umthombo wokukhanya ngokuvamile unezinhlobo ezimbili zomthombo wokukhanya we-laser nomthombo wokukhanya we-LED. Ifayibha yemodi eyodwa isebenzisa umthombo wokukhanya we-laser, i-fiber enemodi eminingi isebenzisa umthombo wokukhanya we-LED.
Okungenhla ukuqhathaniswa kwesakhiwo esiyisisekelo se-fiber yemodi eyodwa kanye ne-multi-mode fiber elethwe yi-Shenzhen HDV.I-Phoelectron Technology LTD., ngesamba samaphuzu angu-3 ongawachaza, ngethemba lokusiza labo abadinga usizo. I-Shenzhen HDV Phoelectron Technology LTD ngokuyinhloko isekelwe emikhiqizweni yokuxhumana yokukhiqiza abakhiqizi, ukukhiqizwa kwamanje kwemishini ihlanganisa:I-ONUuchungechunge, uchungechunge lwamamojula optical,OLTuchungechunge, uchungechunge lwe-transceiver. Ingahlinzeka ngezinsizakalo ezenziwe ngezifiso ezimweni ezehlukene zezidingo zenethiwekhi, wamukelekile ukuthi uze uzobonisana.
