Zvikanganiso zvitanhatu zvakajairika zvematransceivers efiber optic

Fiber optic transceiver iyuniti yekushandura midhiya yeEthernet transmission iyo inochinjana masaini emagetsi anotenderedzwa-pair ari kure uye masaini emagetsi ari kure. Inonziwo photoelectric converter (Fiber Converter) munzvimbo dzakawanda.

1. Chiedza cheLink hachibatidzi

(1) Tarisa kana tambo ye optical fiber yakavhurika;

(2) Tarisa kana kurasikirwa kwetambo ye optical fiber kwakanyanya, izvo zvinopfuura huwandu hwemuchina unogamuchira;

(3) Tarisa kana optical fiber interface yakabatana nemazvo, iyo TX yemuno yakabatana neRX iri kure, uye iyo TX iri kure yakabatana neRX yemuno. (d) Tarisa kana optical fiber connector yakaiswa nemazvo mu device interface, kana jumper type inoenderana ne device interface, kana device type inoenderana ne optical fiber, uye kana transmission length ye device inoenderana nedaro.

2. Mwenje wedunhu reLink haubatidzi

(1) Tarisa kana tambo yenetwork yakavhurika;

(2) Tarisa kana rudzi rwekubatanidza rwuchienderana: makadhi enetwork nemarouter nezvimwe zvishandiso zvinoshandisa tambo dzecrossover, uye maswichi, mahub nezvimwe zvishandiso zvinoshandisa tambo dzakatwasuka;

(3) Tarisa kana mwero wekutumirwa kwemudziyo unoenderana.

3. Kurasikirwa kukuru kwepaketi yenetiweki

(1) Nzvimbo yemagetsi yetransceiver uye network device interface, kana duplex mode ye device interface kumativi ese hazvienderane;

(2) Pane dambudziko netambo yakamonyoroka uye musoro weRJ-45, saka tarisa;

(3) Dambudziko rekubatanidza fiber, kana jumper yakabatana neinterface yemudziyo, kana pigtail inoenderana nejumper uye rudzi rwe coupler, nezvimwewo;

(4) Kana kurasikirwa kwetambo ye optical fiber kuchidarika kunzwisisika kwemuchina.

4. Kana fiber optic transceiver yabatanidzwa, mativi maviri haagone kutaurirana

(1) Kubatana kwefiber kunodzoserwa shure, uye fiber yakabatana neTX neRX inotsiviwa;

(2) RJ45 interface nemudziyo wekunze hazvina kubatana nemazvo (teererai nzira yekupinza nekupinza). Optical fiber interface (ceramic ferrule) haienderane. Kukanganisa uku kunonyanya kuratidzwa mu100M transceiver ine photoelectric mutual control function, senge APC ferrule. Pigtail yakabatana netransceiver yePC ferrule haizotaurirane zvakanaka, asi haizokanganisi non-optical mutual control transceiver.

5. Batidza uye dzima chiitiko

(1). Zvingangodaro kuti kuderedzwa kwenzira ye optical kwakakura zvakanyanya. Panguva ino, mita yemagetsi ye optical inogona kushandiswa kuyera simba re optical remugumo wekugamuchira. Kana iri pedyo nenzvimbo yekugamuchira, inogona kutongerwa sekutadza kwenzira ye optical mukati mehuwandu hwe1-2dB;

(2). Zvingangodaro kuti switch yakabatana netransceiver ine chikanganiso. Panguva ino, chinja switch nePC, kureva kuti, matransceiver maviri akabatana zvakananga nePC, uye magumo ese ari maviri ari PING. Kana ikasaonekwa, inogona kutongerwa seswitch. Chikanganiso;

(3). Transceiver inogona kunge isina kunaka. Panguva ino, unogona kubatanidza magumo ese etransceiver kuPC (usapfuure ne switch). Kana magumo ese asina dambudziko nePING, tumira faira hombe (100M) kana kupfuura kubva kumugumo mumwe kuenda kune mumwe, uye cherechedza kumhanya kwayo, kana kumhanya kwacho kuchinonoka (mafaira ari pasi pe200M anogona kutamiswa kweanopfuura maminetsi gumi nemashanu), inogona kutongerwa sekukundikana kwetransceiver.

6. Mushure mekunge muchina wadonha wotangazve, unodzokera kune zvakajairika

Chiitiko ichi chinowanzo kukonzerwa neswitch. Switch iyi ichaita CRC error detection uye length verification padata rese rakagamuchirwa. Kana chikanganiso chikaonekwa, packet icharaswa, uye packet chaiyo ichatumirwa.

Zvisinei, mamwe mapaketi ane zvikanganiso mukuita uku haagone kuonekwa muCRC error detection uye length check. Mapaketi akadaro haazotumirwi kana kuraswa panguva yekutumira. Achaungana mu dynamic buffer. (Buffer), haagone kutumirwa. Kana buffer yazara, ichaita kuti switch irove. Nekuti panguva ino kutangazve transceiver kana kutangazve switch kunogona kudzorera kutaurirana kuti kuenderane nekwakajairika.
