Izintambo zefayibha zemodi eyodwa kanye nemodi eningi ziyizinhlobo ezimbili ezihlukile zezintambo ze-optical ezisetshenziswa ekuxhumaneni ngocingo kanye nenethiwekhi yedatha. Ziyahlukahluka ngezici eziningana ezibalulekile okuhlanganisa ububanzi bazo obuyinhloko, ibanga lokudlulisa, i-bandwidth, kanye nohlobo lokukhanya ezikusekelayo.

I-Fiber yemodi eyodwa (i-SMF):

Ububanzi be-Core: I-fiber yemodi eyodwa ngokuvamile inobubanzi obuncane obuphakathi, ngokuvamile obungama-microns angu-9 (µm).

Ukudluliselwa Kokukhanya: I-fibre yemodi eyodwa ivumela imodi eyodwa yokukhanya ukuthi isakazeke nge-fibre. Lokhu kusho ukuthi ukukhanya kuhamba ngqo phansi nge-fibre ngaphandle kokugxuma emaphethelweni, okuholela ekuhlakazekeni okuncane kanye nokuncishiswa.

Ibanga Lokudlulisela: I-fiber yemodi eyodwa inikeza amabanga okudlulisa amade uma kuqhathaniswa ne-fiber yemodi eminingi. Ingasekela amabanga angamashumi amakhilomitha kuya kwamakhilomitha angaphezu kwekhulu ngaphandle kokonakala okukhulu kwesiginali.

Ububanzi bomkhawulo: I-fiber yemodi eyodwa inikeza i-bandwidth ephezulu uma kuqhathaniswa ne-fiber yemodi eminingi. Lokhu kuvumela amazinga aphezulu edatha kanye nokudluliswa kwedatha okuphumelelayo kakhulu emabangeni amade.

Izicelo: I-fiber yemodi eyodwa ivame ukusetshenziswa kumanethiwekhi okuxhumana akude, ukuxhumana kwe-inthanethi okusheshayo, kanye nengqalasizinda yomgogodla lapho kudingeka khona i-bandwidth ephezulu kanye namabanga okudlulisa amade.

I-Multimode Fiber (MMF):

Ububanzi be-Core: I-fiber ye-Multimode ngokuvamile inobubanzi obukhulu be-core, ngokuvamile cishe ama-microns angu-50 noma angu-62.5 (µm).

Ukudluliselwa Kokukhanya: I-fibre ye-Multimode ivumela izindlela eziningi zokukhanya ukuthi zisakazeke nge-fibre. Lokhu kuphumela ekuhlakazekeni okuphezulu kanye nokuncishiswa uma kuqhathaniswa ne-fibre ye-single-mode.

Ibanga Lokudlulisela: I-fiber ye-Multimode isekela amabanga okudlulisa amafushane uma kuqhathaniswa ne-fiber yemodi eyodwa. Ngokuvamile isetshenziselwa amabanga afinyelela kumamitha angamakhulu amaningana kuya kumakhilomitha ambalwa.

Ububanzi bomkhawulo: I-fiber ye-Multimode inikeza i-bandwidth ephansi uma kuqhathaniswa ne-fiber yemodi eyodwa. Nakuba ingasekela amazinga aphezulu edatha emabangeni amafushane, ayisebenzi kahle emabangeni amade ngenxa yokusabalala okuphezulu.

Izicelo: I-fiber ye-Multimode ivame ukusetshenziswa ezinhlelweni zokusebenza zebanga elifushane njengenethiwekhi yendawo (ama-LAN), izikhungo zedatha, kanye nezixhumanisi zokuxhumana zebanga elifushane ngaphakathi kwezakhiwo noma amakhampasi.

Ngamafuphi, ukukhetha phakathi kwe-single-mode kanye ne-multimode fiber kuncike ezintweni ezifana nebanga lokudlulisa, i-bandwidth edingekayo, ukucatshangelwa kwesabelomali, kanye nezidingo ezithile zohlelo lokusebenza lwenethiwekhi. I-single-mode fiber ikhethwa kakhulu kwizinhlelo zokusebenza zebanga elide, i-bandwidth ephezulu, kuyilapho i-multimode fiber ifaneleka kumabanga amafushane kanye nezidingo ze-bandwidth ephansi.
