Optical connectors anoshandiswa kubatanidza pakati petiweki zvishandiso panzvimbo dzedata uye yekubatanidza kwefiber optic tambokumidziyo panzvimbo yevatengi (semuenzaniso FTTH).Pakati pemhando dzakasiyana dzefiber connector, SC uye LC ndiwo maviri eanonyanya kushandiswa anobatanidza.SC vs LC: ndeupi mutsauko uye ndeipi iri nani?Kana musati mava nemhinduro.Unogona kuwana chiziviso pano.
Chii chinonzi SC Connector?
Yakagadzirwa nemarabhoritari kuNippon Telegraph neTerefoni (NTT) pakati pemakore makumi masere, SC yekubatanidza yaive imwe yekutanga yekubatanidza kurova musika zvichitevera kuuya kweceramic ferrules.Dzimwe nguva inonzi "square yekubatanidza" iyo SC ine yekusundira-kudhonza coupling yekupedzisira kumeso ine chitubu chakaremerwa ceramic ferrule.Pakutanga yaiitirwa Gigabit Ethernet networking, yakamisikidzwa kuita telecommunications specification TIA-568-A muna 1991 uye zvishoma nezvishoma yakakura mukuzivikanwa sezvo mutengo wekugadzira wakadzika.Nekuda kwekuita kwayo kwakanaka yakatonga fiber optics kweanopfuura makore gumi neST chete yaikwikwidza nayo.Makore makumi matatu zvichienda mberi, inoramba iri yechipiri inonyanya kuzivikanwa yekubatanidza polarization kuchengetedza maapplication.Iyo SC yakanyatsokodzera datacoms uye telecoms application zvinosanganisira point to point uye passive optical network.
Chii chinonzi LC Connector?
Inofungidzirwa nevamwe kuve kutsiva kwemazuva ano kweSC yekubatanidza, kuunzwa kweLC yekubatanidza hakuna kubudirira, muchidimbu nekuda kwemari dzerezinesi dzakakwira kubva kumugadziri Lucent Corporation.Seyekusundidzira-kudhonza yekubatanidza zvakare, iyo LC inoshandisa latch inopesana neSC yekukiya tebhu uye nediki ferrule inozivikanwa sediki fomu factor yekubatanidza.Kuve nehafu yetsoka yeSC yekubatanidza kunopa kukurumbira kukuru mumadatacoms uye mamwe akakwira-density chigamba maapplication, sezvo musanganiswa wehukuru hudiki uye latch chimiro chinoita kuti ive yakanakira kune ane vanhu vakawanda racks / mapaneru.Nekuunzwa kweLC inoenderana transceivers uye inoshanda networking zvikamu, kukura kwayo kwakasimba muFTTH arena kungangoenderera mberi.
SC vs LC: Masiyano Avanoita Kubva Kune Mumwe Nomumwe
Mushure mekuva nekunzwisisa kwekutanga kwezvese SC uye LC yekubatanidza, unogona kubvunza kuti ndeipi misiyano uye inorevei pakuita kwako?Tafura iri pazasi inopa mhedziso yesimba neutera.Uye kazhinji kutaura, mutsauko uripo pakati peLC neSC fiber optic yekubatanidza uri muhukuru, mabatiro uye nhoroondo yekubatanidza, iyo ichakurukurwa zvichiteerana mune inotevera chinyorwa.
- Saizi: LC ihafu saizi yeSC.Chaizvoizvo, imwe SC-adapta ndiyo yakaenzana saizi se duplex LC-adapter.Naizvozvo LC iri kuwedzera uye kuwanda mumahofisi epakati apo kurongedza density (nhamba yekubatanidza panharaunda) chinhu chakakosha chinodhura.
- Kubata: SC ndeyechokwadi "push-pull-connector" uye LC i "latched connector", kunyange zvazvo kune hunyanzvi, chaihwo "push-pull-LCs" huripo hune hunyanzvi hwekubata seSC.
- Nhoroondo yeConnector: Iyo LC ndiyo "mudiki" yekubatanidza yevaviri, SC yakapararira kutenderera pasirese asi LC iri kubata.Ose maatanidzi ane zvakafanana yekuisa kurasikirwa uye kudzoka kurasikirwa kugona.Kazhinji, zvinoenderana nekwaunoda kushandisa munetiweki, zvisinei SC kana LC, kunyangwe mamwe marudzi akasiyana ekubatanidza.
Summary
Yazvino uye yeramangwana tekinoroji yekukurukurirana inoda kukurumidza, inobudirira uye yakachengeteka kuita mukufambiswa kwedata.Mahombe uye akaoma dhatabhesi ese akabatana anofanirwa kukwanisa kugamuchira uye kutumira data pasina kukanganiswa kwekunze.Ose SC uye LC akagadzirirwa kuwana yakadaro mhando yekufambisa.Kana uri mubvunzo "SC vs LC: chii chakasiyana uye ndeipi iri nani?", Unongoda kuchengeta pfungwa nhatu dzinokosha: 1. SC ine hombe yekubatanidza imba uye yakakura 2.5mm ferrule.2. LC ine imba diki yekubatanidza uye diki 1.25mm ferrule.3. SC yaimbova hasha dzose, asi ikozvino LC.Iwe unogona kukwana mamwe mainterface pamutsara-makadhi, mapaneru, nezvimwe neLC yekubatanidza.
