Optical fiber transceiver is an Ethernet transmission media conversion unit iyo inotsinhana kure-kure-monyoroka masaini masaini emagetsi uye kureba-kure-kupenya masaini. Iyo inonyanya kukamurwa kuva single-fiber optical transceivers uye maviri-fiber optical transceivers zvinoenderana nezvavanoda Tevere, isu tichazivisa zvakadzama chii chinonzi single-mode single-fiber / dual-fiber optical transceiver? Ndeupi musiyano uripo pakati pe-single-mode single-fiber uye single-mode dual-fiber transceivers? Shamwari dzafarira, ngatitarisei!
Chii chinonzi single-modhi single-fiber optical transceiver?
Single-mode single-fiber optical fiber transceiver, imwe-fiber michina inogona kuchengetedza hafu yefiber optical, kureva, kugamuchira data uye kutumira pane imwe fiber.
Single-fiber optical fiber transceiver: Iyo data yakagamuchirwa uye inotumirwa inotumirwa pane imwe optical fiber. Sezvinoreva zita, imwe-fiber michina inogona kuchengetedza hafu yefiber optical, ndiko kuti, kugamuchira uye kutumira data pane imwe fiber, iyo yakakodzera kwazvo munzvimbo dzine fiber zviwanikwa. Rudzi urwu rwechigadzirwa runoshandisa tekinoroji yewavelength division multiplexing, uye wavelengths inoshandiswa kazhinji 1310nm uye 1550nm. Nekudaro, nekuti hapana chiyero chepasirese chakabatana che-single-fiber transceiver zvigadzirwa, zvigadzirwa zvevagadziri vakasiyana zvinogona kunge zvisingaenderane kana zvakabatana. Pamusoro pezvo, nekuda kwekushandiswa kwewavelength division multiplexing, single-fiber transceiver zvigadzirwa zvinowanzove nehunhu hwekuremerwa kwechiratidzo. Parizvino, mazhinji emagetsi e-optical fiber transceivers pamusika ane maviri-fiber zvigadzirwa. Zvigadzirwa zvakadaro zvakakura uye zvakagadzikana, asi zvinoda mamwe optical fibers.
Chii chinonzi single-modhi dual-fiber optical transceiver?
Single-mode dual-fiber optical transceiver, single-fiber bidirectional optical transceiver type is photoelectric conversion equipment, zvakanakira kuchengetedza hafu yefiber optical.
Single-fiber bidirectional optical fiber transceiver is photoelectric conversion device inoshandisa wavelength division multiplexing tekinoroji kuendesa uye kugamuchira data pane imwechete optical fiber uye kushandura network magetsi masaini uye masaini masaini. Single-fiber bidirectional fiber optic transceivers yave yakakurumbira mumakore achangopfuura. Chakanakira ndechekuti inogona kuchengetedza hafu yefiber optical, uye kushaikwa kwehafu yefiber optical ndeyekuti parizvino hapana yakabatana yepasirese mwero. Zvigadzirwa zvinogadzirwa nevagadziri vakasiyana zvinowanzoenderana uye zvishoma zvishoma kugadzikana pane zvigadzirwa zviviri-fiber. Parizvino, iyo fiber optic transceivers pamusika ichiri kutungamirwa nemhando mbiri-fiber zvigadzirwa.
Ndeupi musiyano uripo pakati pe-single-mode single-fiber uye single-mode dual-fiber transceivers?
Single-mode multimode zvinoenderana netambo yemaziso. Single-fiber dual-fiber inoreva imwe-core optical fiber transmission kana maviri-core optical fiber transmission; single-mode inoreva kushandisa single-modhi optical fiber tambo. Ose ari maviri akabatana kune iyi musimboti, uye ma transceivers pamativi ese ari maviri anoshandisa akasiyana optical wavelengths, saka vanogona kuendesa masaini masaini mune imwe musimboti. Iyo mbiri-fiber transceiver inoshandisa macores maviri, imwe kutumira uye imwe kugamuchira, uye imwe mugumo ndiyo inotumira magumo uye imwe magumo inofanira kuiswa muchiteshi chekugamuchira, ndiko kuti, migumo miviri inofanira kuyambuka.
Mune mamwe maapplication, single-mode dual-mode, huwandu hwema-multi-mode hwakakwira pane imwe-mode, kunyanya mu wiring renji isingasviki 500m, akawanda-mode anogona kutosangana, kunyangwe kuita kwacho kusiri kwakanaka senge imwe chete. -modhi. Single modhi inoshandiswa munharaunda inopfuura 500m kana yakakwirira bandwidth zvinodiwa, kunyanya munzvimbo dzakakura senge bhizinesi-level application. Nemhaka yokuti kushanda kugadzikana uye kushanda kwe optical fiber modules zviri nani zvikuru kupfuura transceivers, mu-single-mode application environments nepamusoro pekuita zvinodiwa, makambani mashomanana achashandisa transceivers, asi anoshandisa zvakananga modules panzvimbo. Kune vashoma vagadziri veanalog transceivers uye mitengo yakakwira.
Iyo imwe faibha uye mbiri faibha kazhinji ine madoko maviri, uye madoko maviri ehuviri fiber ari padyo neimwe. Iwo akanyorwa TX, RX, imwe kutumira uye imwe inogashira, zvichiteerana. Iwo maviri madoko eimwe fiber anowanzo ari P1. P2 inoratidza kuti madoko ese ari maviri anogona kutumirwa uye kugashirwa zvakasiyana, ndiko kuti, imwe chiteshi inoshandiswa kutumira uye kugamuchira, saka inonzi imwe fiber. Iwo optical transceivers TX uye RX anomiririra kugamuchira uye kutumira. Kune marudzi maviri e-optical transceivers: imwe ndeye-single-mode uye imwe ine mbiri-modhi, kungofanana nemigwagwa mikuru inogona kungozara kana paine mutsara mumwe chete, asi yakanyanya kutsvedzerera kana iri mbiri-mutsara, saka. zviri pachena kuti kugadzikana kweiyo mbiri-modhi inogamuchira Yakanaka point.
Single fiber ingori imwe fiber yekubatanidza pakati peaviri transceivers, mbiri fiber inonyanya kuwanda, iwe unofanirwa kushandisa mafiber maviri, mutengo weimwe fiber wakakwira zvishoma. I-multi-mode transceiver inogamuchira maitiro akawanda ekufambisa, kureba kwekufambisa kunenge kupfupi, uye imwe-mode transceiver inogamuchira chete nzira imwe chete; chinhambwe chekufambisa chakareba. Kunyangwe akawanda-modhi ari kubviswa, asi nekuda kwemutengo wakaderera, kuchine akawanda ari kushandiswa mukutarisa uye kupfupi-chinhambwe kutapurirana. Multi-mode transceivers inoenderana ne-multi-mode optical fibers, single-mode uye single-mode inopindirana, uye haigoni kusanganiswa.
