Optical fiber transceiver iEthernet transmission media conversion unit iyo inochinjanisa masaini mapfupi-akamonyoroka-peya masaini emagetsi uye kureba-kure-kuona masaini.Inonziwo fiber converter munzvimbo dzakawanda.
Optical fiber transceivers inowanzo shandiswa munzvimbo chaidzo dzetiweki dzisingagoni kuvharwa netambo dzeEthernet uye dzinofanira kushandisa optical fibers kuti iwedzere kureba kwekutapurirana, uye dzinowanzowanikwa muchikamu chekupinda maapplication ebroadband metropolitan area network;zvakadai se: high-definition video image transmission for monitoring and security engineering;Inoitawo basa rakakura mukubatsira kubatanidza mamaira ekupedzisira efiber kune metro nekupfuura.
Optical fiber transceivers ichasangana nematambudziko akasiyana panguva yekushandiswa.Nhasi, ini ndichagovera newe zvikanganiso zvakajairika uye mhinduro dze optical fiber transceivers.
1. Chiedza che Link chakadzimwa
(1) Tarisa uone kana mutsetse wefiber optical wakatyoka;
(2) Tarisa kana kurasikirwa kweiyo optical fiber line yakakura uye inodarika iyo yekugamuchira iyo midziyo;
(3) Tarisa uone kana iyo optical fiber interface yakabatana nemazvo, iyo yemuno TX yakabatana neiyo iri kure RX, uye iri kure TX yakabatana neRX yeko.
(4) Tarisa uone kana iyo optical fiber yekubatanidza yakanyatso kuisirwa mudhizaini interface, kana rudzi rwejumper ruchienderana nedhizaini, kana rudzi rwechishandiso ruchienderana neoptical fiber, uye kuti kureba kwekutapurirana kwemudziyo kunopindirana nedaro.
2. The redunhu Link chiedza chakadzimwa
(1), tarisa kana network tambo yakavhurika sedunhu;
(2) Tarisa uone kana mhando yekubatanidza ichienderana: iyo network kadhi uye marouters uye zvimwe zvishandiso zvinoshandisa crossover tambo, uye switch, hubs uye zvimwe zvishandiso zvinoshandisa dzakatwasuka-kuburikidza netambo;
(3) Tarisa uone kana mwero wekutapurirana wemudziyo unoenderana.
3. Yakakomba network packet kurasikirwa
(1) Chiteshi chemagetsi che transceiver hachifananidzi chiratidziro chetiweki mudziyo, kana iyo duplex modhi yechishandiso chemuchina pamigumo yese;
(2) Kana pane dambudziko nepeya yakamonyoroka uye musoro weRJ-45, tarisa;
(3) Optical faibha yekubatanidza matambudziko, ingave iyo jumper yakabatana neiyo mudziyo interface, ingave pigtail inoenderana nejumper uye coupler mhando, nezvimwewo;
(4) Kunyangwe kurasikirwa kweiyo optical fiber line inodarika kugamuchirwa kwekunzwa kwemidziyo.
4. Mushure mokunge optical fiber transceiver yakabatanidzwa, migumo miviri haigoni kutaurirana
(1) Mafibisi optical anodzoserwa shure, uye optical fibers akabatana neTX neRX anodzoserwa shure;
(2) Kubatana pakati peRJ45 interface uye chigadzirwa chekunze hachina kururama (teerera kune yakananga-kuburikidza uye splicing) uye optical fiber interface (ceramic ferrule) haifanani.Mhosva iyi inonyanya kuratidzwa mu100M transceiver ine optoelectronic mutual control function, senge APC ferrule.Kana iyo pigtail yakabatanidzwa kune transceiver yePC ferrule, haizokwanisi kutaurirana zvakajairika, asi haizokanganisi kubatana kwe-non-optical-electrical mutual control transceiver.
5. Pa uye kure chiitiko
(1) Zvingave kuti iyo yekuona nzira yekudzikisira yakakurisa.Panguva ino, mita yemagetsi optical inogona kushandiswa kuyera simba rekuona rekupedzisira kwekugamuchira.Kana iri pedyo nekugamuchira sensitivity range, inogona kunyanya kutongwa sekutadza kwenzira yekuona mukati mehuwandu hwe1-2dB;
(2) Zvingave kuti switch yakabatana kune transceiver yakanganisa.Panguva ino, shandura shanduko nePC, kureva kuti, ma-transceivers maviri akabatanidzwa zvakananga kuPC, uye migumo miviri inoputirwa.Mhosva;
(3) Transceiver inogona kunge isina kukanganisa.Panguva ino, unogona kubatanidza migumo yese ye transceiver kuPC (kwete kuburikidza nekuchinja).Mushure mokunge migumo miviri isina dambudziko nePING, tumira faira huru (100M) kubva kune rumwe rutivi kuenda kune rumwe.Tarisa Kumhanya Kwayo, sekunonoka zvakanyanya (kuchinjisa mafaera ari pasi pe200M kweanopfuura maminetsi gumi nemashanu), inogona kutongwa sekutadza kwetransceiver.
6. Mushure mekurovera nekutangazve, ichadzokera kune yakajairika
Ichi chiitiko chinowanzo kukonzerwa nekuchinja.Iyo switch ichaita CRC yekuona kukanganisa uye kutarisa kureba pane ese akagamuchirwa data.Iwo mapaketi ane zvikanganiso acharaswa, uye iwo chaiwo mapaketi achaendeswa mberi.
Nekudaro, mamwe mapaketi akakanganisa mune iyi maitiro haagone kuonekwa muCRC yekuona kukanganisa uye kutariswa kwehurefu.Mapaketi akadaro haatumire kana kuraswa panguva yekuendesa mberi, uye anozoungana muine dynamic buffer.(buffer), haigone kutumirwa kunze.Kana buffer yazara, ichaita kuti switch iparare.Nekuti panguva ino kutangazve transceiver kana kutangazve switch kunogona kuita kuti kutaurirana kudzokere kune kwakajairika.
