Xa kusakhiwa iziko ledatha, kusetyenziswa inethiwekhi ye-FTTH, okanye kuphuculwa iziseko zoqhagamshelwano lweentambo zeshishini, abathengi abaninzi bacinga ukuba zonke iintambo ze-fiber patch zisebenza ngendlela efanayo. Nangona kunjalo, ngokwesiqhelo, umahluko kuhlobo lwefayibha, ukupholisha isixhumi, izinto zejakethi, kunye nolwakhiwo lwentambo kunokuchaphazela ngokuthe ngqo uzinzo lwenethiwekhi kunye nokusebenza kothumelo. Ukukhetha okungalunganga intambo yepetshikunokukhokelela ekuncipheni okuphezulu, imiqondiso engazinzile, okanye ixesha lokungasebenzi elingalindelekanga emva kokufakwa. Yiyo loo nto ukukhetha iinkcukacha ezifanelekileyo kwimeko yokusetyenziswa kwayo kubalulekile.
Yasekwa ngo-2006,I-Oyi International, Ltd.yinkampani evelisa i-fiber optic eseShenzhen enamava aphantse abe yiminyaka engama-20 kwiimveliso zonxibelelwano lwe-fiber kunye nezisombululo ze-optical ezenzelwe wena. I-OYI igxile ekuveliseni okuthembekileyo, ulawulo lomgangatho olungqongqo, kunye nemveliso ye-OEM/ODM eguquguqukayo.
Khetha EchanekileyoUhlobo lweFayibha
Inyathelo lokuqala kukufumanisa ukuba usetyenziso lufuna ifayibha yemowudi enye okanye yemowudi ezininzi na. Ukusebenzisa uhlobo olungalunganga yenye yezona zinto zixhaphakileyo zokulahleka kwesiginali kunye nokungaphumeleli kwekhonkco.
1.Intambo yePatch yeModi enye(OS1/OS2)
Iintambo zepetshi zemowudi enye zine-fiber core eyi-9μm evumela ukukhanya ukuba kuhambe ngokusasazwa okuncinci, nto leyo eyenza ukuba zilungele unxibelelwano lwe-optical olukude. Ngokuxhomekeke kuyilo lwenethiwekhi kunye nokusebenza kwezixhobo, umgama wokudlulisela ungahluka ukusuka kwiikhilomitha ezimbalwa ukuya kwiikhilomitha ezingaphezulu kwe-100.
Ngenxa yokukwazi kwazo ukugcina ukuthembeka kwesignali kumgama omde, iintambo zepetshi zemowudi enye zisetyenziswa kakhulu kwiinethiwekhi zonxibelelwano nakwezinye iiprojekthi ezinkulu zeziseko zophuhliso ze-optical.
Izicelo eziqhelekileyo ziquka:

Kwezi meko, ukuncitshiswa okuphantsi kunye nomgangatho wesignali ohambelanayo kubalulekile. Iintambo ze-OS2 ze-OS2 ze-single-mode patch ze-OYI zenziwa kwaye zavavanywa ukuqinisekisa ukusebenza okuthembekileyo kwiinethiwekhi ze-optical ze-bandwidth ephezulu, ezixhasa usetyenziso oluqala kwiziseko zonxibelelwano zomgangatho wenkampani ukuya kwiinkqubo zanamhlanje zothumelo lwe-10G, 100G, kunye nesantya esiphezulu.
2.Intambo yePatch yeMultimode (OM2/OM3/OM4/OM5)
I-Multimode fiber inobukhulu obukhulu be-core, ngesiqhelo i-50μm okanye i-62.5μm, nto leyo eyenza ukuba ifaneleke kakhulu ekudlulisweni kwedatha ngesantya esiphezulu, umgama omfutshane ngaphakathi kwezakhiwo nakwiindawo zekhampasi. Ukusebenza kwayo kakuhle kweendleko kunye nokuhambelana nezicelo ze-bandwidth ephezulu kwenze ukuba ibe lukhetho oludumileyo kwiinethiwekhi zeshishini kunye namaziko edatha anamhlanje.
6) Izicelo eziqhelekileyo ziquka:
7) Uqhagamshelo lwe-rack-to-rack kwiziko ledatha
8) Iinkqubo ze-Enterprise LAN
9) Iinethiwekhi zeseva kunye nendawo yokugcina (SAN)
10) Iindawo ezikumaziko edatha ezinoxinano olukhulu
11) Iintambo zomqolo ezikufutshane ngaphakathi kwezakhiwo
Iintambo ze-OM3 kunye ne-OM4 multimode patch zisetyenziswa kakhulu kwiindawo zedatha ukuxhasa uthumelo lwe-10G, 40G, kunye ne-100G Ethernet kumgama ofikelela kwiimitha ezingama-300. I-OM5 iphucula ngakumbi ukusetyenziswa kwe-bandwidth ngokusebenzisa i-shortwave wavelength division multiplexing (SWDM), nto leyo eyenza ukuba ibe lukhetho olunomtsalane kwiziseko zesiseko sedatha esinoxinano olukhulu kwisizukulwana esilandelayo kunye nezicelo zothumelo lwedatha olukhawulezayo.
TshatisaIsinxibelelanisiThayipha kwiZixhobo Zakho
Ukuhambelana kwesixhumi yenye into ebalulekileyo ekufuneka iqwalaselwe. Abathengi kufuneka baqinisekise zombini ifomathi yesixhumi kunye nohlobo lokupholisha ngaphambi kokuba bathenge.
1.IsiXhobo se-LC
Izihlanganisi ze-LC zincinci kwaye zixhasa ukufakelwa okuxineneyo. Zisetyenziswa kakhulu ngee-transceivers ze-SFP kunye ne-SFP+ kumaziko edatha anamhlanje.
