Optical connectors yog siv rau kev sib txuas ntawm network pab kiag li lawm ntawm cov ntaub ntawv chaw zov me nyuam thiab rau kev sib txuas ntawmfiber ntau optic cablerau cov khoom siv ntawm cov neeg siv khoom thaj chaw (xws li FTTH).Ntawm ntau hom fiber ntau connector, SC thiab LC yog ob qho ntawm feem ntau siv connectors.SC vs LC: qhov txawv thiab qhov twg zoo dua?Yog koj tseem tsis tau teb.Koj tuaj yeem pom qee qhov qhia ntawm no.
SC Connector yog dab tsi?
Tsim los ntawm lub chaw soj nstuam ntawm Nippon Telegraph thiab Xov Tooj (NTT) nyob rau hauv nruab nrab-800, SC connector yog ib qho ntawm cov thawj connectors mus ntaus lub lag luam tom qab lub advent ntawm ceramic ferrules.Qee lub sij hawm hu ua "square connector" SC muaj lub laub-rub coupling kawg lub ntsej muag nrog lub caij nplooj ntoos hlav loaded ceramic ferrule.Pib npaj rau Gigabit Ethernet kev sib txuas lus, nws tau ua qauv rau hauv kev sib txuas lus tshwj xeeb TIA-568-A hauv xyoo 1991 thiab maj mam loj hlob hauv qhov chaw raws li cov nqi tsim khoom tau nqis los.Vim nws qhov kev ua tau zoo heev nws tau tswj hwm fiber ntau optics rau ntau tshaj kaum xyoo nrog tsuas yog ST sib tw nrog nws.Peb caug xyoo dhau los, nws tseem yog qhov thib ob feem ntau txuas rau polarization tswj kev siv.SC yog qhov tsim nyog rau kev siv datacoms thiab telecoms suav nrog taw tes rau taw tes thiab passive optical networking.
LC Connector yog dab tsi?
Kev txiav txim siab los ntawm qee qhov kev hloov pauv niaj hnub ntawm SC connector, kev taw qhia ntawm LC connector tsis ua tiav, ib feem vim yog cov nqi ntawv tso cai siab pib los ntawm tus tsim khoom Lucent Corporation.Raws li lub laub-rub connector kuj, LC siv lub latch uas tsis yog SC locking tab thiab nrog ib tug me me ferrule nws yog hu ua ib tug me me daim ntawv connector.Muaj ib nrab ntawm cov hneev taw ntawm SC connector muab nws qhov chaw loj hauv datacoms thiab lwm yam kev siv thaj chaw siab, vim nws qhov sib xyaw me me thiab latch feature ua rau nws zoo tagnrho rau cov neeg coob coob racks / panels.Nrog rau kev qhia txog LC tau tshaj transceivers thiab cov khoom siv sib txuas ua haujlwm, nws txoj kev loj hlob tsis tu ncua hauv FTTH arena zoo li yuav txuas ntxiv mus.
SC vs LC: Lawv txawv li cas ntawm ib leeg
Tom qab muaj kev nkag siab yooj yim ntawm ob qho tib si SC thiab LC connector, koj tuaj yeem nug dab tsi yog qhov txawv thiab lawv txhais li cas rau koj qhov kev siv?Cov lus hauv qab no muab cov ntsiab lus ntawm qhov muaj zog thiab qhov tsis muaj zog.Thiab feem ntau hais lus, qhov sib txawv ntawm LC thiab SC fiber ntau optic connector nyob rau hauv qhov loj me, kev tuav thiab cov ntaub ntawv txuas keeb kwm, uas yuav tau tham txog nyob rau hauv cov ntawv hauv qab no.
- Loj: LC yog ib nrab ntawm SC.Qhov tseeb, ib qho SC-adapter yog qhov loj tib yam li duplex LC-adapter.Yog li ntawd LC yog ntau thiab ntau dua nyob rau hauv lub hauv paus chaw ua hauj lwm qhov twg packing ceev (tus naj npawb ntawm kev sib txuas ib cheeb tsam) yog ib qho tseem ceeb tus nqi.
- Kev tuav: SC yog qhov tseeb "push-rub-connector" thiab LC yog "latched connector", txawm hais tias muaj cov tshiab, tiag tiag "push-rub-LCs" muaj uas muaj peev xwm tuav tau zoo ib yam li SC.
- Keeb Kwm ntawm Kev Sib Txuas: LC yog qhov "yooj yim" txuas ntawm ob, SC tau nthuav dav thoob ntiaj teb tab sis LC tab tom ntes.Ob lub connectors muaj tib qhov kev nkag tsis tau thiab rov poob peev xwm.Feem ntau, nws nyob ntawm qhov twg hauv lub network koj xav siv cov khoom txuas, tsis hais SC lossis LC, txawm tias lwm yam sib txawv ntawm cov khoom sib txuas.
Cov ntsiab lus
Tam sim no thiab yav tom ntej kev sib txuas lus thev naus laus zis xav tau ceev, ua haujlwm tau zoo thiab nyab xeeb hauv cov txheej txheem kev sib txuas lus cov ntaub ntawv.Cov ntaub ntawv loj thiab nyuaj txhua qhov sib cuam tshuam yuav tsum tau txais thiab xa cov ntaub ntawv yam tsis muaj kev cuam tshuam sab nraud.Ob leeg SC thiab LC yog tsim los ua kom tiav ib hom kev sib kis.Raws li rau lo lus nug "SC vs LC: qhov txawv thiab qhov twg yog qhov zoo dua?", koj tsuas yog yuav tsum khaws peb lub ntsiab lus hauv siab: 1. SC muaj lub vaj huam sib luag loj dua thiab loj dua 2.5mm ferrule.2. LC muaj lub vaj huam sib luag me me thiab me me 1.25mm ferrule.3. SC siv tag nrho cov npau taws, tab sis tam sim no nws yog LC.Koj tuaj yeem haum ntau qhov sib cuam tshuam ntawm kab ntawv, vaj huam sib luag, thiab lwm yam nrog LC connector.
