Cov lus nug nquag
Q: Dab tsi yog 4 hom fiber ntau optic connectors?
A: LC, SC, ST, thiab MPO / MTP npog feem ntau ntawm kev teeb tsa niaj hnub. LC tswj hwm kev tsim kho tshiab thiab transceiver- txuas txuas, SC tseem yog tus qauv rau FTTH thiab cov lag luam qub txeeg qub teg, ST tseem nyob hauv cov txheej txheem LAN qub hauv kev saib xyuas kev sib hloov, thiab MPO/MTP yog tus qauv rau txhua qhov sib npaug - optic xa tawm ntawm 40G thiab siab dua.
Q: Kuv puas tuaj yeem sib xyaw UPC thiab APC connectors?
A: Tsis yog - yeej tsis. Lub ntsej muag kawg ntawm APC connector yuav raug puas ntsoog mus tas li yog hais tias mated rau lub tiaj tus UPC ferrule, thiab qhov tshwm sim poob yuav ua rau qhov txuas tsis siv tau. Ib txwm phim polish hom hla txhua qhov txuas. Lub rooj sib tham ntsuab vs xiav khau raj xim muaj tseeb los tiv thaiv qhov yuam kev no.
Q: Puas yog LC thiab SC connectors interchangeable?
A: Tsis yog. Lawv yog cov khoom sib txawv ntawm cov khoom sib txawv nrog cov kab sib txawv ferrule (1.25 mm vs 2.5 mm) thiab sib txawv coupling mechanisms. Koj tuaj yeem txuas nruab nrab ntawm lawv siv LC hybrid - mus rau -SC thaj qaum los yog LC / SC hybrid adapter vaj huam sib luag, tab sis lawv tsis ncaj nraim nrog phooj ywg.
Q: Dab tsi fiber connector muaj qhov qis tshaj qhov poob?
A: Thaum txiav tawm kom raug, ntxuav, thiab tshuaj xyuas, tus nqi hwm - qib LC, SC, thiab E2000 connectors tag nrho mus txog IEC 61753 Qib B (tsawg dua lossis sib npaug li 0.25 dB). Hom Connector tseem ceeb tsawg dua qhov kev txiav tawm zoo thiab kev huv. Tus kab mob qib B txuas yuav ua tau zoo dua qib C txuas huv - tab sis tsuas yog kom txog thaum nws qias neeg.
Q: Vim li cas APC connector khau raj ntsuab?
A: Kev lag luam convention standardized hauv TIA-568. Lub kaum sab xis yuav tsum tsis pom qhov pom kev pom los tiv thaiv kev puas tsuaj los ntawm kev sib tsoo UPC. Ntsuab yog lub teb ceeb toom xim uas qhia cov kws kho qhov txuas no yuav tsum tau APC-tshaj mating hardware.
Q: Kuv yuav ua li cas thiaj paub yog tias kuv lub connector yog tib -hom lossis multimode?
A: khau raj xim yog qhov taw qhia ceev tshaj plaws: xiav lossis ntsuab khau raj=ib zaug - hom; aqua lossis txiv qaub ntsuab khau raj=multimode. Lub tsho cable xim (daj=ib zaug-mode, aqua/lime=multimode) muab kev pom zoo thib ob. Thaum tsis ntseeg, nyeem cov ntawv txuas lossis cov ntaub ntawv cable - khau raj xim cov rooj sib tham yog tus qauv tab sis tsis muaj kev tswj hwm thoob plaws txhua lub tuam txhab.
Q: Qhov txawv ntawm MTP thiab MPO yog dab tsi?
A: MPO yog tus qauv (txhais hauv IEC 61754-7). MTP yog ib lub cim lag luam ntawm US Conec rau qhov siab dua - kam rau ua, teb - pabcuam MPO connector. MTP thiab MPO connectors yog mechanically interoperable - lawv mate ncaj qha. MTP connectors muab kev nkag tau zoo dua qhov tsis sib xws thiab lub tsev tshem tawm tau rau re- polishing, tab sis ob qho tib si npe xa mus rau ntau- fiber ntau thawb-on technology. Hauv kev xyaum, yog tus neeg muag khoom hais koj MTP rau hauv MPO vaj huam sib luag, nws yuav ua haujlwm.
