- Ukuphathwa kwekhwalithi okuqinile kuqinisekisa ukusebenza okulinganayo kusukela ekukhiqizeni kuya ekufakweni kwensimu.
Umphumela uba yi-Cable Patch Cord eletha ukudluliswa kwedatha okuzinzile, okusheshayo, okusekela izidingo ze-bandwidth zamanethiwekhi e-FTTH anamuhla. Ukuzibophezela kukaDowell ekhwalithini nasekusunguleni izinto ezintsha kubeka lo mkhiqizo njengesinqumo esihamba phambili sokuxhumeka kwe-fiber optic okuthembekile ngo-2025.
Ukufakwa Kwentambo Yesiqeshana Sekhebula, Ukuhambisana, kanye Nokuqinisekisa Ikusasa
Ukuphatha Nokuqondisa Okulula Ezindaweni ze-FTTH
Abafaki bavame ukubhekana nezimo eziyinkimbinkimbi lapho besebenzisa amanethiwekhi e-fiber-to-the-home. Intambo yekhebula ye-2.0×5.0mm SC UPC Cable Patch ibhekana nalezi zinselele ngomklamo omncane noguquguqukayo owenza kube lula ukudlula ezindaweni ezixineneyo kanye nemigudu enabantu abaningi. Onjiniyela be-Dowell bathuthukise i-sheath kanye nesakhiwo sangaphakathi ukuze bamelane nokugoba nokuphathwa njalo, baqinisekise ukuthi ikhebula ligcina ukusebenza kahle ngokuhamba kwesikhathi.
Izintambo zokulahla ze-fiber optic eziqediwe ngaphambiliniziye zabonakala zisebenza kahle ekufakweni kwe-FTTH ngokunciphisa isikhathi sokufaka, ukuthuthukisa ikhwalithi, nokunciphisa amaphutha endaweni. Izifundo zamacala zasemadolobheni nasemakhaya zibonisa ukuthi izintambo eziqediwe kusengaphambili zivumela ukuthunyelwa okusheshayo, ukonga izindleko, kanye nezinkinga ezimbalwa zokulungisa.
- Ukufakwa kwezintambo ngendlela efanele, okuhlanganisa nokusetshenziswa kwamathileyi ezintambo nama-hook, kusekela ukufakwa okuphumelelayo.
- Ukuqinisa kahle kuvimbela ukulimala kwefayibha futhi kwandise isikhathi senkonzo.
- Abasebenzi abaqeqeshiwe kanye nemibhalo ephelele kusiza ekugcineni ukusebenza kwenethiwekhi isikhathi eside.
Amanethiwekhi Optical Angasebenzi (ama-PON) enza kube lula kakhulu ukufakwa ngokusebenzisa izingxenye ezimbalwa ezisebenzayo futhi akhonze amakhasimende amaningi ngefayibha eyodwa. Lokhu kulula kokwakha, kuhlanganiswe nezintambo eziqinile, ezingamelani nesimo sezulu, kuholela ekutheniukulungiswa okumbalwa kanye nezindleko zokulungisa eziphansi.
Ukuhambisana Kwedivayisi Ebanzi Nenethiwekhi
Intambo ye-Dowell's Cable Patch Cord ikhombisa ukuhambisana okubanzi nezinhlobo eziningi zehadiwe yenethiwekhi. Umkhiqizo uthwalaUhlu lwe-UL lwe-US ne-Canada, kanye nokuvunyelwa kwe-GSA, okuqinisekisa ukuhambisana nezindinganiso zokuphepha eziqinile kanye nekhwalithi. Lezi zitifiketi zenza intambo ye-patch ifanelekele izindawo zenethiwekhi ezahlukahlukene nezidinga amandla.
Izintambo zokubopha ezivela eDowell zihlolwa ngokuqinile isiteshi kanye nesixhumanisi esihlala njalo ukuqinisekisa ukusebenza.Izindinganiso ze-RoHS, ETL, UL, kanye ne-ISO, ukuqinisekisa ukusebenza okuthembekile kokubili kumanethiwekhi akudala nawanamuhla. Ama-cores ethusi angenawo umoya-mpilo ohlanzekile kakhulu kanye nezinketho zokuvikela ezithuthukisiwe zifaka isandla ekuqhubekiseni ukusebenza okuzinzile futhi kunciphise ukulahleka kwesignali.
Ukuhlaziywa kokusetshenziswa kwenethiwekhi kugqamisa izinzuzo zokuhambisana ezindaweni zamadivayisi ezinabantu abaningi.Izakhiwo ezisatshalaliswayo, njenge-Remote PHY kanye ne-Remote MAC-PHY, isekela ukusebenza kahle kanye nokuphathwa okungcono kwesikhala, amandla, kanye nokupholisa. Izintambo ze-fibre optic patch ezine-imicu engazweli ukugoba kanye nobuchwepheshe bokulahlekelwa obuphansi kakhulugcina ukusebenza kwenethiwekhi ngisho nasezindaweni eziningi zokufakwa. Ukuphela kwefektri kanye nezixhumi ezihlanzekile kuqinisekisa ukuhlanganiswa okungenamthungo nezingqalasizinda ezithuthukisiwe.
Ukuhlolwa komuntu wesithathu kuqinisekisa ukuthi izintambo zokubopha ezisezingeni eliphezulu nezihlolwe kahle ziqinisekisa ukusebenza kahle kwenethiwekhiImikhiqizo kaDowell ihlangabezana noma idlula njaloIzidingo zokusebenza ze-TIA/EIA-568-B, okunikeza isiqinisekiso sokusebenzisana neziteshi ze-OEM kanye nokuhambisana okubuyela emuva nezinhlelo ezindala.
Ukuhambisana Nezindinganiso Zakamuva ze-FTTH
Ukuzibophezela kukaDowell ekhwalithini kubonakala ekunamatheleni kwe-Cable Patch Cord ezindinganisweni zakamuva ze-FTTH. Ireferensi yokuhlolwa kwekhwalithi yentambo ye-fibre patchIzindinganiso zobuchwepheshe ze-IEC, ezichaza amapharamitha abalulekile njenge-fibre end face geometry kanye nezilinganiso zokusebenza. La mapharamitha aqinisekisa ukuthi izixhumi ze-optical zigcina ubuqotho besignali futhi zinciphisa ukulahleka.
