Basa guru refiber optic connector nderekukurumidza kubatanidza mafibhi maviri kuitira kuti chiratidzo chemaziso chirambe chichigadzira nzira yemaziso. Fiber optic connectors is mobile, reusable, uye ndiyo inonyanya kukosha uye inonyanya kushandiswa passive components mu optical communication systems.Iyo fiber optic connectors inobvumira kuti zviso zviviri zvekupedzisira zvefiber zvive zvakanyatsobatanidzwa kuti zviwedzere kubatanidzwa kwemagetsi emagetsi. kubva pakutumira fiber kusvika kune fiber inogamuchira, uye migumisiro yegadziriro nekuda kwekupindira kwayo inoda kuderedzwa. Nekuti iyo dhayamita yekunze yefiber inongova 125um, uye chikamu chinopfuudza chiedza chidiki, iyo single-mode fiber inongosvika 9um, uye multimode fiber i50um uye 62.5um, saka kubatana pakati pemafibhi kunofanirwa kuve kwakanyatso. zvakaenzanirana.
Core components: ferrule
Kuburikidza nebasa refiber optic connector, zvinogona kuonekwa kuti chikamu chepakati chinokanganisa kushanda kwechibatanidza ndiyo ferrule. Unhu hwechigadziko hunokanganisa zvakananga nzvimbo yakanyatsogadziriswa yefibers maviri.Iyo inogadzirwa neceramic, simbi kana plastiki. Ceramic ferrule inoshandiswa zvakanyanya, iyo huru zvinhu ndeye zirconium dioxide, iyo ine hunhu hwekudzikama kwemafuta, kuomarara kwepamusoro, kunyungudika kwakakwira, kupfeka kuramba uye kurongeka kwepamusoro. Sleeve ndiyo imwe chikamu chakakosha chekubatanidza, uye sleeve inoshanda seyakagadziriswa kuti iite kuti kukwidziridzwa kwekubatanidza. Iyo dhayamita yemukati yeceramic sleeve idiki zvishoma pane dhayamita rekunze reiyo ferrule, uye sleeve yakatsemurwa inoomesa maviri ferrules kuti anyatso kurongeka.
Kuitira kuti zviso zvekupedzisira zvemafibhi maviri zvibatane zviri nani, magumo eferrule anowanzo kugadzika kuita zvimiro zvakasiyana. PC, APC, uye UPC inomiririra kumberi kwekupedzisira chimiro checeramic ferrule. PC is Physical Contact, kubatwa kwemuviri.PC ine micro-spherical surface yakakwenenzverwa uye yakakwenenzverwa, pamusoro peferrule inogayiwa kuita zvishoma spherical surface, uye musimboti weoptical fiber unowanikwa panzvimbo yepamusoro pekukotama kuitira kuti. zviso zviviri zvefiber end zviri mukubatana kwenyama.APC (Angled Physical Contact) inonzi beveled physical contact, uye fibre end face inowanzogadzikwa kusvika pa8° bevel. Iyo 8 ° angled bevel inoita kuti faibha inoguma kumeso kusimba uye inoratidzira mwenje kuburikidza nekona yayo yakabhenda kune yakavharwa pachinzvimbo chekudzoka yakananga kutsime, ichipa zvirinani kubatanidza kuita. UPC (Ultra Physical Contact), super physical end face.UPC yakavakirwa paPC kuti igadzirise kupera kwechiso kupepereswa uye kupera kwepamusoro, iyo yekupedzisira kumeso inotaridzika zvakanyanya dome-yakaita. Kubatana kwekubatanidza kunofanirwa kunge kuri mune imwechete yekupedzisira chiso chimiro, semuenzaniso APC neUPC haigone kusanganiswa, zvichikonzera kuderedzwa kwekoniki kuita.
Basic parameters: kuisa kurasikirwa, kudzoka kurasikirwa
Nekuda kweakasiyana ferrule end zviso, kuita kweiyo connector kurasikirwa kwakasiyanawo. Kushanda kwemaziso kwefiber optic connectors inonyanya kuyerwa nematanho maviri ekutanga: kurasikirwa kwekuisa uye kurasikirwa kwekudzoka. Saka, chii chekuisa kurasikirwa? Insertion Loss ("IL") isimba rekuona kurasikirwa nekuda kwekubatana.Inonyanya kushandiswa kuyera kurasikirwa kwemaziso pakati pezvikamu zviviri zvakagadziriswa mufiber, kazhinji nekuda kwekutsauka kwemashure pakati pemafibhi maviri, iyo longitudinal gap mu. fiber joint, kunaka kwechiso chekupedzisira, etc. Iyo unit inoratidzirwa mu decibels (dB). Iyo diki iyo iri nani, iyo yakawanda inodiwa haifanirwe kunge inopfuura 0.5dB.
Return Loss ("RL") inoreva parameter yechiratidzo chekuratidzira kuita. Inotsanangura kurasikirwa kwesimba kwe optical signal return/reflection. Kazhinji, iyo yakakura zviri nani, kukosha kunowanzo kuratidzwa mumadecibel (dB). Yakajairika APC yekubatanidza ine yakajairwa RL kukosha inosvika -60 dB uye PC yekubatanidza ine yakajairika RL kukosha inosvika -30 dB.
Mukuwedzera kune maviri optical performance parameters yekuisa kurasikirwa uye kurasikirwa kwekudzoka, kushanda kwefiber optic connector kunofanirawo kubhadhara kune kuchinjana, kudzokorora, simba rekugadzirisa uye kupisa kwekushanda kwefiber optic connector. , nhamba yezvinyorwa uye zvichingodaro.
Connector type
Izvo zvibatanidza zvakakamurwa maererano nenzira yekubatanidza: LC, SC, FC, ST, MU, MT, MPO / MTP, nezvimwewo; maererano nefiber end face: FC, PC, UPC, APC.
LC connector
Iyo LC-mhando yekubatanidza inogadzirwa ine nyore kushandisa modular jack (RJ) latch mechanism. Saizi yemapini nemaoko anoshandiswa muLC connector i1.25 mm, inova saizi yeyakajairika SC, FC, nezvimwewo, saka saizi yekunze inongova hafu yeiyo yeSC/FC.
SC connector
Iyo yekubatanidza yeSC connector ('Subscriber Connector' kana 'Standard Connector') is a snap-on standard square connector, iyo inosungirirwa neplugging nekuburutsa, uye haidi kutenderedzwa. Mhando iyi yekubatanidza inogadzirwa nemapurasitiki einjiniya, ayo asingadhure uye ari nyore kuisa nekubvisa.
FC connector
Iyo FC fiber connector (Ferrule Connector) uye SC connector yakaenzana saizi, kunze kwekuti FC yakagadzirwa nesimbi sleeve uye nzira yekusimbisa ndeye turnbuckle. Iyo yekushandisa modhi ine zvakanakira chimiro chakareruka, kushanda kuri nyore, kugadzira kuri nyore uye kusimba, uye inogona kushandiswa munzvimbo yakakwirira yekudengenyeka.
ST connector
Iyo ST fiber optic yekubatanidza (Yakatwasuka Tip) ine denderedzwa rekunze casing ine 2.5mm yakaita mhete yepurasitiki kana simbi casing. Nzira yekutsanya ndeye turnbuckle, iyo inowanzoshandiswa mufiber distribution frames.
MTP/MPO connector
Iyo MTP/MPO fiber optic yekubatanidza imhando yakakosha yeakawanda-fiber yekubatanidza. Chimiro cheMPO connector chakaoma, chinobatanidza 12 kana 24 fibers mune rectangular fiber ferrule. Inowanzo shandiswa kune yakakwirira-density yekubatanidza mamiriro senge data centers.
Pamusoro pezviri pamusoro apa, mhando dzekubatanidza ndeye MU zvibatanidza, MT zvinongedzo, MTRJ zvinongedzo, E2000 zvinongedzo, nezvimwe zvakadaro. SC ingangove ndiyo inonyanya kushandiswa fiber optic yekubatanidza, kunyanya nekuda kwekudhura kwayo dhizaini. LC fiber optic connectors zvakare inowanzoshandiswa fiber optic connector, kunyanya yekubatanidza kuSFP uye SFP + fiber optic transceivers. FC inonyanya kushandiswa mune imwe chete modhi uye isingawanzo mu multimode fiber. Magadzirirwo akaomarara uye kushandiswa kwesimbi kunoita kuti ive inodhura. ST fiber optic connectors inowanzo shandiswa mumarefu uye mapfupi maficha ekushandisa senge kambasi uye yekuvaka multimode fiber application, bhizinesi network nharaunda, uye zvechiuto zvikumbiro.
