Kana mapurojekiti asina kusimba akasangana nekutapurirana kure-kure, fiber optics inowanzoshandiswa. Nekuda kwekuti kureba kwemafiber optical kureba, kazhinji, kureba kweiyo single-mode fiber inopfuura makiromita gumi, uye kureba kwekufambisa kwema-multi-mode fiber kunogona kusvika kumakiromita maviri.
Mu fiber optic network, tinowanzo shandisa fiber optic transceivers. Saka, sei kubatanidza fiber optic transceivers? Ngatitarisei pamwe chete.
Kutanga, basa re fiber optic transceivers
① Iyo optical fiber transceiver inogona kuwedzera kureba kwekufambisa kweEthernet uye kuwedzera iyo yekuvhara radius yeEthernet.
② Iyo optical fiber transceiver inogonachinjapakati pe10M, 100M kana 1000M Ethernet yemagetsi interface uye yekuona.
③ Kushandisa fiber optic transceivers kuvaka network kunogona kuchengetedza network invest.
④ Optical fiber transceivers inoita iyo yekubatanidza pakati pemaseva, anodzokorora, hubs, zviteshi uye materminal nekukurumidza.
⑤ Iyo optical fiber transceiver ine microprocessor uye diagnostic interface, iyo inogona kupa akasiyana data link performance performance.
Chechipiri, itransceiver ipi ine transceiver yemaziso uye inogamuchira ipi?
Paunenge uchishandisa optical fiber transceivers, shamwari zhinji dzinosangana nemibvunzo yakadai:
1.Ko optical fiber transceivers inofanira kushandiswa pairi?
2.Is optical fiber transceiver yakakamurwa kuita imwe yekugamuchira uye imwe yekutumira? Kana kuti matransceivers maviri ekuona anogona kushandiswa sepaya here?
3. Kana iyo optical fiber transceivers ichifanira kushandiswa paviri, zvakakosha here kuti ndeyemhando imwechete uye muenzaniso? Kana kuti chero mhando dzinogona kushandiswa pamwe chete?
Mhinduro: Optical fiber transceivers anowanzo shandiswa ari maviri maviri semafotoelectric shanduko midziyo, asi zvakare zvinokwanisika kubatanidza fiber optic transceivers nefiber.switches, fiber optic transceivers uye SFP transceivers. Muchidimbu, chero bedzi iyo optical transmission wavelength yakafanana Iyo chiratidzo encapsulation fomati yakafanana uye zvese zvinotsigira imwe protocol kuti iwane optical fiber kutaurirana.
Kazhinji, single-mode dual-fiber (mafibhi maviri anodiwa pakukurukurirana kwakajairwa) ma transceivers haana kukamurwa kumagumo ekutumira uye magumo ekugamuchira, uye anogona kushandiswa chero achionekwa ari maviri maviri.
Chete-fiber transceiver (imwe fiber inodiwa pakukurukurirana kwakajairwa) ichava nemagumo ekutumira uye magumo ekugamuchira.
Mune mamwe mazwi, mitengo yakasiyana (100M neGigabit) uye yakasiyana-siyana yavelengths (1310nm uye 1300nm) haigoni kutaurirana. Mukuwedzera, kunyange kana imwe fiber transceiver uye mbiri fiber yemhando imwechete yakabatanidzwa, hazvibviri kutaurirana kune mumwe nemumwe. Interoperable.
Saka mubvunzo ndewekuti, chii chinonzi fiber transceiver uye chii chinonzi dual fiber transceiver? Ndeupi musiyano pakati pavo?
Chii chinonzi single-fiber transceiver? Chii chinonzi dual-fiber transceiver?
Iyo single-fiber transceiver inoreva kune imwechete-modhi optical tambo. Iyo single-fiber transceiver inoshandisa chete musimboti uye migumo yese yakabatana kune iyi musimboti. Iwo ma transceivers pamativi ese ari maviri anoshandisa akasiyana optical wavelengths, saka anogona kufambiswa mune imwe musimboti Chiedza chiratidzo.
A dual-fiber transceiver anoshandisa macores maviri, imwe yekutapurirana uye imwe yekugamuchira, uye imwe mugumo inofanira kuiswa kune imwe mugumo, uye migumo miviri inofanira kuyambuka.
1.Single fiber transceiver
Iyo single-fiber transceiver inofanirwa kuita zvese zviri zviviri basa rekutumira uye basa rekugamuchira. Inoshandisa wavelength division multiplexing tekinoroji kuendesa uye kugamuchira maviri masaini masaini ane akasiyana wavelengths pane imwe optical fiber.
Nokudaro, iyo-single-mode-single-fiber transceiver inoparadzirwa kuburikidza ne-core optical fiber, saka chiedza chekutumira uye kugamuchira chinoparidzirwa kuburikidza ne-fiber core panguva imwe chete. Muchiitiko ichi, kuti uwane kutaurirana kwakajairwa, mafungu maviri emwenje echiedza anofanirwa kushandiswa kusiyanisa.
Nokudaro, iyo optical module ye-single-mode-single-fiber transceiver ine wavelengths maviri echiedza chakabudiswa, kazhinji 1310nm / 1550nm. Nenzira iyi, pane misiyano pakati pemigumo miviri yevaviri ve transceivers:
Iyo transceiver kune imwe mugumo inotumira 1310nm uye inogamuchira 1550nm.
Imwe magumo iri kubudisa 1550nm uye kugamuchira 1310nm.
Saka zviri nyore kuti vashandisi vasiyanise, uye kazhinji shandisa mavara pachinzvimbo.
A-terminal (1310nm / 1550nm) uye B-terminal (1550nm / 1310nm) yakaonekwa.
Vashandisi vanofanira kushandisa AB pairing, kwete AA kana BB kubatana.
AB yekupedzisira inoshandiswa chete kune imwechete fiber optic transceivers.
2.Dual fiber transceiver
Iyo mbiri-fiber transceiver ine TX port (yekutumira port) uye RX port (inogamuchira chiteshi). Madoko ese ari maviri anofambisa pahurefu hwakafanana hwe1310nm, uye iyo yekugamuchira iri zvakare 1310nm. Naizvozvo, iwo maviri anoenderana optical fibers anoshandiswa mu wiring akabatana-akabatana.
3. Nzira yekusiyanisa sei imwe fiber transceiver kubva kune mbiri fiber transceiver?
Parizvino pane nzira mbiri dzekusiyanisa ma-single-fiber transceivers kubva kune maviri-fiber transceivers.
① Kana iyo optical transceiver yakaiswa ne optical module, iyo transceiver optical inokamurwa kuita imwe-fiber transceiver uye dual-fiber transceiver maererano nenhamba yemacores akabatana optical fiber jumper. Iyo mutsara weiyo optical fiber jumper yakabatana kune imwe-fiber transceiver (kurudyi) ndeye fiber core, iyo inobata kune zvese kutumira uye kugamuchira data; Mutsara ndiwo macores maviri. Imwe musimboti ine basa rekufambisa data uye imwe musimboti ine basa rekugamuchira data.
②Kana iyo optical fiber transceiver isina embedded optical module, inofanirwa kusiyanisa pakati pe fiber imwe chete transceiver uye mbiri fiber transceiver maererano neyakaiswa optical module. Kana imwe-fiber bidirectional optical module inoiswa mu optical fiber transceiver, kureva kuti, iyo inoshandiswa imhando ye simplex, optical fiber transceiver is single-fiber transceiver (mufananidzo wakarurama); apo maviri-fiber bidirectional optical module akaiswa mu optical fiber transceiver, Ndiko kuti, kana iyo interface iri duplex rudzi, iyi transceiver i-dual-fiber transceiver (kuruboshwe mufananidzo).
Chechina, chiratidzo uye kubatana kweiyo optical fiber transceiver
1.Indicator ye optical fiber transceiver
Kune chiratidzo cheiyo optical fiber transceiver, isu tine yapfuura chinyorwa chakapihwa kune izvi zvirimo.
Pano tinodzokorora kuburikidza nemufananidzo kuti tijekese.
2.Fiber optic transceiver connection
