Ama-Fiber optics ngokuvamile athandwa ezimbonini ezihlukahlukene ngenxa yokusebenza kahle kwawo okukhulu kanye nekhono eliphezulu lokudlulisa idatha. Ngale ndlela, ungakwazi ukudlulisa idatha ngaphandle kokuthintwa ukuphazamiseka kwangaphandle nangaphakathi. Ukudluliswa kwenziwa nge-multi-mode noma i-single-mode fiber kuye ngezidingo zokuxhumana.

Ukuze kuguqulwe imodi yefayibha, izindlela ezihlukene zokuguqula ziyadingeka uma ibanga liyingxenye ebalulekile ezinhlelweni zokubona. Isiguquli semidiya ye-fiber ye-MM singasiza ekudaleni indawo ephephile yokudluliswa kwedatha ngaphakathi kwamasistimu okukhanya noma izingxenye.

Amakhebula emodi eyodwa nawemodi eningi
Izintambo zemodi eyodwa zakhelwe ukuthwala ukukhanya ziqonde phansi kufiber. Inokudluliselwa kwedatha yemodi eyodwa kanye nobubanzi obungama-microns angu-8.5-10 kuyilapho imodi eminingi ngokuvamile ilungele amabanga amafushane. Uma kuqhathaniswa nemodi eminingi, izintambo ze-patch zemodi eyodwa zine-bandwidth ephakeme kodwa zidinga umthombo wokukhanya onobubanzi obuncane be-spectral.

Imicu yemodi eminingi ithwala umkhawulokudonsa ophezulu ngesivinini esikhulu. Amakhebuli ahamba isikhathi eside kunamamitha angu-914,4, ama-cable pat amaningi angaholela ekuphazamisekeni ekugcineni kokwamukela, okubangela ukudluliswa okungaqinisekile nokuyingxenye.

Lapho Ukuguqulwa Kudingeka?
Inethiwekhi ye-fiber optic ayibandakanyi kuphela ukusetshenziswa kohlobo olulodwa lwefayibha, kodwa ezimweni eziningi, ungase udinge ukuguqulwa kwemodi phakathi nokudluliswa kwedatha, ikakhulukazi i-MMF iye ku-SMF. Ukuguqulwa kwemodi phakathi kwe-MM ne-SM fibers ngokuvamile kuyadingeka lapho ibanga lenethiwekhi lidlula umkhawulo we-MM fiber.

Futhi, ukuguqulwa kwe-MMF ne-SMF kuyadingeka kuye ngesisetshenziswa kanye nohlobo lokuxhumana kunethiwekhi. Isibonelo, ingxenye yefa ebiza kancane isebenzisa imbobo ye-MM futhi ukuxhumeka kuyadingeka engxenyeni ye-SM.

Uyiguqula kanjani i-Multi-Mode ibe yimodi eyodwa?
Njengoba ukuguqulwa kwemodi kunethiwekhi yokubona kuthathwa njengokwendawo yonke, kunezindlela ezintathu zokuguqulwa kwemodi eminingi ukuya kwemodi eyodwa. Ake sizibheke:

I-Fiber kuya ku-Fiber Media Converter
I-Fiber to fibre media converter ingaba yisixazululo esisebenzayo sokuthuthukisa inethiwekhi ye-MM phezu kwamafayibha e-SM anamabanga afika ku-140 km.

I-WDM Transporter
Isithuthi se-WDM esivame ukusetshenziswa ezinhlelweni ze-WDM, ikakhulukazi ezinhlelweni ze-DWDM ngoba ekuhambeni kwesikhathi eside kokudluliselwa, ukuguqulwa kwe-MMF kuya ku-SMF noma i-SMF kuya ku-MMF kuyadingeka.

I-Mode Conditioning Fiber Patch Cord
Intambo yesichibi semodi yokufaka umoya yethula i-laser ngokunembile ukusuka maphakathi ne-MM fiber. Lokhu kuphumela ekusakazeni i-laser kububanzi be-fiber core, kunciphise umthelela owaziwa ngokuthi ukulibaziseka kwemodi ehlukile (i-DMD) okwenzeka lapho i-laser ihlangana nenani elincane lamamodi ku-MM fiber.

Isiguquli semidiya ye-fiber siyingxenye yokuxhumana esebenza kahle engasiza ukuxhuma nokudlulisa amasignali phakathi kwe-fiber optic cabling nezinye izinhlobo zemidiya yekhebula njengezintambo ze-Ethernet zethusi ne-UTP (ipheya esontekile engavikelekile).

Kungasiza ukwelula impilo yemishini yenethiwekhi nezitshalo zokufaka izintambo. Udinga uxhumano lwe-fiber optic uma ibanga phakathi kwezinto ezimbili zenethiwekhi lidlula ibanga lokudlulisela lekhebula yethusi.
