Nekutaurirana kwemaziso, optical interfaces yemidziyo yakabatana kuburikidza neoptical fiber.Semuenzaniso, kubatana pakati peOLT uyeONU(kazhinji kutaura, SFP optical module inodiwa kuti ipe optical interface yekubatanidza paOLT), uye kuendesa data pakati pemaviri optical fiber transceivers kunoitwawo kuburikidza neoptical fiber, saka zita rechimiro chavo rinova ruzivo rwekutanga mukukurukurirana kwemaziso.
Kune marudzi maviri e optical fiber interfaces: nechimiro uye nekuguma chiso.Zvikamu zviviri izvi hazvina kupindirana, asi zvinogarisana.Kufanana neSC/APC mumufananidzo uri pazasi, iyo yaimbova SC ndeimwe yeyakagadziriswa classification, uye iyo yekupedzisira APC ndeimwe yemagumo ekupedzisira.
Kurongeka kwechimiro
1. FC round thread
Iyo FC interface yefiber optical ine nzvimbo yakasimudzwa zvishoma, uye iyo FC interface yeimwe yakatarisana mudziyo ine gap chinzvimbo.Izvo zviviri zvinofanirwa kuenderana.Mushure mekugadzirisa, isa optical fiber uye shandura chimiro chekunze (nut) kuti upedze kugadzirisa.Kana iyo bulge isingaenderane negap, simbisa nati, uye kutapurirana kwechiedza pakati pezviviri kuchava nekurasikirwa kukuru.
Zvakanakira: Mushure mokunge nzvimbo yacho yakarongeka uye yakasimbiswa, optical fiber uye chigadziro chakabatanidzwa zvakasimba.
Zvakaipa: Iyo plugging yakaoma uye kuisirwa kunotora nguva yakareba.
2. ST bayonet round type
Musoro we ST unogadziriswa nebayonet mushure mokunge waiswa uye kutenderera hafu yedenderedzwa.Izvo zvakashata ndezvekuti zviri nyore kuputsika.
3. SC bayonet square muromo mukuru
Iyo inonyanya kureva iyo yakagadziriswa chinzvimbo cheplug uye latch mhando (yezasi kuruboshwe nhamba iSFP Optical module)
Zvakanakira: yakanakira yakananga plugging uye nyore kushanda
Zvakaipa: Kuenzaniswa neFC interface, kubatana hakuna kunyanya kusimba.
4. LC muromo diki mativi
LC idiki pane SC maererano ne fiber core uye chitarisiko.LC ndeye modular jack (RJ) latch mechanism
Pedzisa kusarudzika kwechiso
1. PC microsphere pamusoro kukuya uye kupukuta
PC (Physical Contact) zvinoreva kubata muviri.Chiedza chinobuda kubva kumagumo efiber optical.Kunyangwe iyo yekupedzisira chiso chemagumo ichijeka uye ichibvumira kuti chiedza chipfuure, pachange paine chiedza chinoratidzwa kumashure, icho chinonzi back reflection.Chiedza chinoratidzwa hachisangana negwara rinotarisirwa rekufambisa uye rinoda kudzvanywa.Chiyero chekudzivisa chinonzi kudzoka kurasikirwa.PC yakatsiviwa zvishoma nezvishoma neUPC.
2, UPC
UPC (Ultra Physical Contact).UPC inovandudzwa pahwaro hwePC.Chiso chekupedzisira cheUPC chakakotama zvishoma.Mushure mekupenya kwenguva yakareba, ine kupedzisa kuri nani kwepamusoro uye kurasikirwa kurinani kwekudzoka pane PC chimiro, asi haina kusimba zvakakwana.Kudzokororwa plugging uye plugging zvinotungamira mukudzikira kwemhando yepamusoro uye yekupedzisira kuita.Kuonekwa kweiyo optical fiber shell paUPC yekupedzisira kumeso kunowanzo kuve yebhuruu.
3. APC iri pakona ye8 madhigirii uye nzvimbo ye microsphere inokuyiwa uye yakakwenenzverwa
Kuenzaniswa nePC, APC ichava neimwe kona yekumisikidza, uye iyo yekupedzisira radius yekuisa inokwenenzverwa pakona ye8 °, nekudaro ichidzikisa kuratidzwa kwemashure.Iko kurasikirwa kwekuona kwekudzoka kweAPC yekubatanidza ndeye - 60dB kana kupfuura, iyo yakakwirira kune mamwe marudzi ekubatanidza.APC ma-connectors anogona chete kuenzaniswa nemamwe ma-angle-polished connectors, asi kwete ne-non-angle-polished connectors, zvikasadaro zvinozokonzera kurasikirwa kwepamusoro.Kuonekwa kweiyo optical fiber shell pane APC yekupedzisira kumeso kunowanzo girini.
Dzimwe sumo
Flange ndiro
Batanidza maviri optical fiber interfaces kuti uwedzere nzira yekuona.Ziva kuti APC inopera kumeso uye UPC yekupedzisira kumeso haigone kusanganiswa.
Dust cap
Iyo inoshandiswa kudzivirira guruva kudzivirira iyo fiber core end face kubva pakusvibiswa, izvo zvinokanganisa iyo optical chiratidzo chekufambisa.
