Ukuqonda ukusebenza kwe-fiber optical nocingo lwethusi kungenza ukukhetha okungcono. Ngakho yiziphi izici i-optical fibre nocingo lwethusi enazo?

1. Izici zezintambo zethusi
Ngaphezu kwalokhu okushiwo ngenhla okuhle kokulwa nokuphazamiseka, ukugcinwa kuyimfihlo, kanye nokufakwa/ukunakekela/ukuphatha okulula kocingo lwethusi, inokuguquguquka okuhle nekhono lokuphakelwa kwamandla ezimo eziphuthumayo, ngisho noma amandla ephelile, ingaqhubeka nokunikeza amandla imishini.

2. Izici ze-Fiber
Ngaphezu komkhawulokudonsa ophezulu kanye nebanga elide lokudlulisela okukhulunywe ngalo ngenhla, i-fiber optical nayo inokunciphiswa okuphansi, ukuthembeka okuhle, ukuqina nokuphepha, futhi ngenxa yokuthi i-fiber optical iyisivikeli, ngeke ithinteke ukuphazanyiswa kwe-electromagnetic kanye ne-crosstalk. Ibeka eceleni kwemishini yezimboni.

Ngokombono wezobuchwepheshe, uhlobo lwemidiya yokudlulisa isikhungo sedatha olufanelekile lungakhethwa ngokusekelwe ezintweni ezintathu ezilandelayo:

1. Liyini ikhono le-medium ukudlulisa amasignali?
Ngamanye amazwi, ingabe ingavikelwa kwezinye izimpawu, futhi kuyini ukusebenza okuphambene nokuphazamiseka? Uma indawo yokufaka izintambo iyimbi noma ikhono lokulwa nokuphazamiseka liphezulu, khetha i-optical fiber.

2. Ingabe udinga ukunikeza amandla ngekhebula?
Kungabonakala kulokhu okungenhla ukuthi ucingo lwethusi lungasetshenziselwa ukunikezwa kwamandla. Uma ukunikezwa kwamandla ngekhebula kudingekile, ucingo lwethusi luyakhethwa.

3. Kuthiwani ngezinkinga zokuthwala noma ukuhamba?
Uma udinga ukushintsha futhi unyakaze njalo, ungakhetha i-fiber enokuzwela ukugoba.

Ngaphezu kwala maphuzu amabili angenhla, zikhona yini ezinye izici okufanele zicatshangelwe? Impendulo ithi “yebo”. Ngaphezu kwezinto ezimbili eziyisisekelo ezishiwo ngenhla, kuyadingeka futhi ukukhetha ngokuya ngohlobo lomsebenzisi, njengesididiyeli sesistimu, usonkontileka kanye nomsebenzisi wokugcina. Kunomehluko omkhulu phakathi kwalokhu okuthathu:

Isididiyeli sesistimu: ukujwayela komkhiqizo nezifanekiso zamanje;
Usonkontileka: ukufaneleka, isikali nokutholakala;
Umsebenzisi wokugcina: umlando wakamuva (ngolwazi lwephrojekthi noma ukuchayeka kokumaketha);

Kumsebenzisi ngamunye, kubaluleke kakhulu ukucabangela izici ezibalulekile. Akuvunyelwe ukuzitshwa noma ukugwema umlando noma ubuchwepheshe, ngoba kufanele sicabangele uhlobo lomsebenzisi ukuze sikhethe i-fibre efanele noma intambo yethusi yokufaka izintambo.

Ngaphansi kwezimo ezijwayelekile, lapho umkhawulokudonsa omkhulu kakhulu kanye nokudluliselwa kwebanga elide kuyadingeka (njenge-industrial Ethernet cabling), i-optical fiber ingakhethwa. Esimeni sebanga elifushane kanye nezinga lokudlulisela eliphansi (njengasebhilidini noma ihhovisi lebhizinisi), intambo yethusi ikhethwa kakhulu. Kuyafaneleka, vele, ungaphinda ukhethe ukuxuba nokufanisa ngokuya ngesimo sangempela somsebenzisi.
