Hla -Kev sib txuas ntawm UPC thiab APC cov cuab yeej raug tshem tawm
Thawj cov ntaub ntawv siv rau qhov no hybrid LC thaj cable yog cov khoom siv txuas nrog cov sib txuas sib txawv. Thaum cov cuab yeej siv network siv LC/APC cov chaw nres nkoj tab sis thaj vaj huam sib luag yog LC / UPC raug txiav tawm (lossis rov ua dua), UPC no -rau -APC fiber ntau jumper tshem tawm qhov xav tau ntawm kev hloov pauv hloov pauv. Yog xav paub ntxiv txog yuav ua li cas cov qauv polishing txawv hauv kev ua tau zoo, saib peb phau ntawv qhiaPC vs UPC vs APC fiber ntau txuas polish hom thiab rov ua haujlwm poob.
FTTH OLT thiab ONU Interconnection
Hauv fiber ntau-rau-- kev xa tawm hauv tsev, OLT cov cuab yeej siv feem ntau siv APC connectors rau qhov zoo rov qab poob, thaum qee cov khoom qub qub ONU muaj UPC interfaces. Qhov no LC UPC-APC hybrid cable muab kev sib txuas ncaj qha ntawm cov khoom siv PON tsis sib haum. Rau tus qauv FTTH khiav qhov twg ob qhov kawg sib faib tib hom polish, pebLC LC ib hom fiber ntau thaj cable rau FTTH thiab cov ntaub ntawv chaw sib txuasyog tus nqi - lwm txoj kev zoo.
CATV Headend thiab Distribution Node Patching
Cable TV optical networks feem ntau xav tau APC connectors kom txo qis rov qab -xav txog hauv analog video signals. Thaum sib koom ua ke UPC-tawm cov cuab yeej xeem lossis cov khoom qub qub, qhov sib txuas txuas txuas rau CATV headend siv tswj cov teeb liab kev ncaj ncees thoob plaws hom kev sib txuas.

FAQ
Q1: Vim li cas kuv thiaj xav tau LC UPC rau LC APC hybrid thaj cable es tsis txhob siv lub adapter?
A: Ib qho tshwj xeeb hybrid patch cable muab qis dua tag nrho cov ntaub ntawv poob piv rau kev siv UPC - rau -APC mating adapter. Txhua qhov kev sib txuas ntawm adapter ntxiv qhov poob thiab qhov muaj peev xwm xav txog cov ntsiab lus. Qhov no ib leeg hybrid jumper nrog lub Hoobkas- polished xaus kom huv si teeb liab hloov thaum txuas UPC thiab APC khoom.
Q2: Dab tsi yog qhov txawv ntawm UPC thiab APC connector polish hom?
A: UPC (Ultra Physical Contact) muaj lub ntsej muag tiaj tus kawg, thaum APC (Angled Physical Contact) muaj 8-degree angled kawg lub ntsej muag. APC connectors muab ntau dua rov qab poob (qis rov qab-review), ua rau lawv nyiam rau analog video thiab high-rhiab heev daim ntaub ntawv. Qhov no hybrid cable txuas ob hom ncaj qha.
Q3: Kuv puas tuaj yeem siv LC UPC no-APC cable rau GPON lossis XGS-PON networks?
A: Yog. Passive optical networks feem ntau muaj OLT ports nrog APC connectors thiab qee qhov ONT / ONU li nrog UPC ports. Qhov no hybrid ib hom thaj cable rau PON xa mus txuas ntxiv xws li kev sib tshuam tsis sib haum yam tsis tas yuav tsum tau hloov kho adapter ntawm txhua qhov kev sib txuas.
Q4: Dab tsi yog G657A1 khoov-insensitive fiber ntau txhais tau tias rau kev teeb tsa?
A: G657A1 fiber ntau tso cai nruj dua khoov radii (tsawg li 10mm) yam tsis muaj teeb meem loj. This makes the hybrid patch cable suitable for confined spaces, dense patch panels, and routing around obstacles where standard G652D fiber would suffer macro-bend attenuation.
Q5: Puas yog lub tsho LSZH ntawm lub cable no xav tau rau kev teeb tsa sab hauv?
A: LSZH (Low Smoke Zero Halogen) tsho tau pom zoo los yog xav tau nyob rau hauv cov chaw kaw xws li cov chaw zov me nyuam, cov tsev ua haujlwm, thiab cov chaw pej xeem. Cov nplaim hluav taws no- cov kab hluav taws xob LC hybrid ua tau raws li cov qauv kev nyab xeeb hluav taws hauv tsev thiab tsim cov pa luam yeeb tsawg heev yog tias raug hluav taws. Rau kev taw qhia txog kev xaiv lub tsho zoo rau ib puag ncig sib txawv, xa mus rau peb tsab xov xwm ntawmSab hauv thiab sab nraum zoov fiber ntau optic cable installation yuav tsum tau thiab xaiv lub tsho.
Q6: Yuav ua li cas rov qab poob kuv xav tau los ntawm APC kawg ntawm no hybrid cable?
A: APC connector kawg feem ntau ua tiav ntau dua los yog sib npaug rau 60dB rov qab poob vim nws lub kaum sab xis. UPC kawg muab ntau dua lossis sib npaug rau 50dB rov qab poob. Ua ke nrog Tsawg dua los yog sib npaug rau 0.3dB qhov kev poob qis, qhov hybrid duplex thaj qaum no tswj cov teeb liab zoo rau kev sib txuas qhov muag pom.
Q7: Qhov no hybrid patch cable puas tuaj yeem siv tau ntev -kev sib kis ib leeg?
A: Yog. Lub 9/125μm ib hom fiber ntau txhawb kev sib kis ntau kis ntawm 1310nm thiab 1550nm wavelengths. Qhov no LC UPC rau APC jumper rau ntev -haul connectivity ua haujlwm nrog tus qauv ib hom transceivers thiab tuaj yeem xa mus rau hauv metro lossis nkag mus rau ntu ntu.
Q8: Puas yog kev cai ntev rau UPC no -APC hybrid fiber ntau cable?
A: Kev cai cable ntev, lub tsho xim, thiab duplex / yooj yim configurations tuaj yeem tsim los txiav txim. Hu rau tus neeg muag khoom kom qhia meej qhov yuav tsum tau ua rau bulk hybrid patch cable xaj lossis project-kev teeb tsa tshwj xeeb.
