Duplex fiber uye polarity
Mukushandiswa kwe10G Optical fiber, maviri optical fibers anoshandiswa kuona maviri-nzira kutapurirana kwedata.Imwe magumo ega yega optical fiber yakabatana kune inotumira uye imwe magumo yakabatana kune inogamuchira.Ose ari maviri akakosha.Tinodzidaidza kuti duplex optical fiber, kana duplex optical fiber.
Saizvozvo, kana paine duplex, pane simplex.Simplex inoreva kuendesa ruzivo mune imwe nzira.Pamigumo miviri yekutaurirana, imwe mugumo ndiyo inotumira uye imwe magumo ndiyo inogamuchira.Sezvakangoita faucet kumba, iyo data inoyerera munzira imwe uye haidzokerike.(zvechokwadi, pane kusanzwisisana pano. Chokwadi, optical fiber communication yakaoma zvikuru. Optical fiber inogona kufambiswa nenzira mbiri. Tinongoda kufambisa kunzwisisa.)
Kudzokera kune duplex fiber, TX (b) inofanira kugara yakabatana neRX (a) zvisinei kuti mangani mapaneru, maadapter kana optical cable zvikamu zviripo mune network.Kana iyo inoenderana polarity isingaonekwe, iyo data haizofambiswa.
Kuti uchengetedze polarity chaiyo, tia-568-c standard inokurudzira AB polarity crossing scheme ye duplex jumper.
MPO/MTP faibha polarity
Saizi yeMPO/MTP yekubatanidza yakafanana neiyo SC yekubatanidza, asi inogona kugarisa 12/24/16/32 optical fibers.Naizvozvo, MPO inogona kuchengetedza zvakanyanya kabati wiring nzvimbo.
Nzira nhatu dzepolar dzakatsanangurwa muTIA568 chiyero dzinonzi nzira A, nzira B uye nzira C zvakateerana.Kuti isangane neTIA568 yakajairwa, MPO/MTP backbone optical tambo dzakakamurwawo kuita kuburikidza, kuyambuka kwakazara uye kuyambuka vaviri, kureva, mhando A (kiyi kumusoro - kiyi pasi nepakati), nyora B (kiyi kumusoro - kiyi kumusoro / kiyi pasi. kiyi pasi yakakwana kuyambuka) uye nyora C (kiyi kumusoro - kiyi pasi peya kuyambuka).
Sezvakaratidzwa mumufananidzo uri pasi apa:
Parizvino tambo dzechigamba dzeMPO/MTP dzinowanzo shandiswa i12-core fiber optic patch cords uye 24-core fiber optic patch cords, asi mumakore achangopfuura 16-core uye 32-core fiber optic patch tambo dzakaonekwa.Mazuva ano, anopfuura zana-core multi-core jumpers ari kubuda, uye kuonekwa kwepolar kweakawanda-core jumpers akadai seMPO/MTP kunova kwakanyanya.
