Connector hom (LC, SC, MU) txhais lub cev vaj tse, ferrule loj, thiab mating mechanism. Polish hom (PC, UPC, lossis APC) txhais cov geometry ntawm lub ntsej muag fiber ntau, uas cuam tshuam qhov rov ua haujlwm poob. Koj yuav tsum tau qhia ob qho tib si thaum xaj ib daim kab xev - tau txais lub connector yog tab sis polish tsis ncaj ncees lawm yuav ua rau ib tug degraded los yog tsis yog -functional link.
LC, SC, thiab MU puas tuaj yeem siv nrog ib qho - hom thiab multimode fiber ntau?
Yog lawm. Tag nrho pebconnector hommuaj nyob rau hauv ob qho tib si -hom thiab multimode versions. Hom connector tsis txiav txim siab fiber ntau hom - uas yog txiav txim los ntawm cable cog, transceiver wavelength, thiab cov fiber core inch (9/125 μm rau ib leeg-hom, 50/125 los yog 62.5/125 μm rau multimode).
Vim li cas feem ntau niaj hnub transceivers siv LC es tsis txhob SC?
Vim tias SFP daim ntawv foos - uas yog qhov tseem ceeb ntawm pob transceiver rau Gigabit thiab 10G Ethernet - tau tsim los kom muaj kev sib haum xeeb dua li GBIC tus thawj coj. Lub LC connector's 1.25 mm ferrule haum rau SFP lub nqaim pem hauv ntej - vaj huam sib luag qhib, thaum lub SC's 2.5 hli ferrule tsis. Raws li SFP modules dhau los ua tus qauv kev lag luam, LC tau los ua tus qauv transceiver interface los ntawm kev txuas ntxiv.
Lub connector twg muaj ntau dua nyob rau hauv passive optical networks?
SC, thiab tshwj xeeb SC / APC. Nyob rau hauv GPON, XG-PON, thiab lwm yam passive optical network architectures, SC/APC connectors yog dav siv rauPLC splitters, optical faib thav duab, thiab cov neeg siv khoom - sab khoom. Lub kaum sab xis txo qis rov qab- kev xav rov qab, uas yog qhov tseem ceeb hauv qhov ntev - ncav cuag, siab - cais- qhov sib piv network tsim.
