Matambudziko anowanikwa mukuisa uye kushandiswa kwefiber optic transceivers
Danho 1: Chekutanga, unoona here kana chiratidzo cheiyo fiber transceiver kana optical module uye yakamonyoroka pair port chiratidzo chiripo?
1.Kana iyo optical port (FX) chiratidzo cheA transceiver chiripo uye chiratidzo che optical (FX) cheB transceiver chisina kuvhenekera, kukanganisa kuri paA transceiver side: imwe mukana ndewe: A transceiver (TX) optical transmission Chiteshi chakaputsika nokuti optical port (RX) yeB transceiver haigamuchire chiratidzo chemaziso.Imwe mukana ndeyokuti pane dambudziko neiyi fiber link yeA transceiver (TX) optical port, yakadai sechiedza. jumper yatyoka.
2.Kana iyo optical port (FX) chiratidzo cheiyo transceiver isingavhenekeri, tarisa kana iyo fiber link yakabatana.Iyo fiber jumper yakabatana mune parallel uye imwe yacho muchinjiko-kubatanidza.
3.The twisted pair (TP) chiratidzo hachivhenekeri.Ndapota ita shuwa kuti tambo yakamonyoroka yakashata kana kuti yakabatana zvisizvo.Ndapota shandisai continuity tester kutarisa.(Zvisinei, mamwe ma transceivers' twisted pair indicators anofanira kumirira kusvika fibre link yabatidzwa).
4.Mamwe ma-transceivers ane maviri maRJ45 ports: (ToHUB) inoratidza kuti mutsara wekubatanidza unobatanidza kushandura mutsara wakarurama.(ToNode) inoratidza kuti tambo yekubatanidza inobatanidza ma switch ndeye muchinjiko-mutsara.
5.Vamwe vashanduri vane MPR kushandura kune rumwe rutivi: mutsara wekubatanidza unobatanidza zvigadzirisheni inzira yakananga-kuburikidza nemutsara.DTE inoshandura: mutsara wekubatanidza unobatanidza zvigadziriswa inzira yemuchinjikwa.
Danho rechipiri: Ongorora kana paine dambudziko nefiber jumper uye tambo?
1.Optical fiber connection on-off yekuona: shandisa laser flashlight, chiedza chezuva, nezvimwewo kuti uvhenekere fiber jumper.Ona kana pane chiedza chinooneka kune rumwe rutivi?Kana pane chiedza chinooneka, fiber jumper haina kuputsika.
2.Cable break yekuona: shandisa laser tochi, chiedza chezuva, chivheneko kuti uvhenekere tambo yekubatanidza kana coupler.Ona kana pane chiedza chinooneka kune rumwe rutivi?Kana pane chiedza chinooneka, tambo haina kuputsika.
Danho rechitatu: Iyo hafu/yakazara duplex nzira yakaipa here?
Mamwe ma transceivers ane FDX switches padivi: duplex yakazara;HDX switch: hafu duplex.
Nhanho 4: Kushandisa optical simba mita yekuona chiridzwa
Simba rinopenya re optical transceiver kana optical module pasi pemamiriro ezvinhu akajairika: multimode: -10db-18db;single mode 20km: -8db–15db;single mode 60km: -5db–12db Kana simba rinopenya re transceiver optical riri pakati -30db–45db, zvino zvinogona kutongwa kuti pane dambudziko ne transceiver iyi.
Optical transceivers anofanirwa kutarisisa zvinhu
Nekuda kwekureruka, zviri nani kuve nemubvunzo uye mhinduro maitiro, ayo anogona kuwanikwa nekungotarisa.
1.Ko iyo optical transceiver pachayo inotsigira yakazara-duplex uye hafu-duplex?
Mamwe machipi pamusika anogona chete kushandisa yakazara-duplex nharaunda parizvino, uye haigone kutsigira hafu-duplex.Kana iwe ukabatanidza kune mamwe mabhureki ekuchinja (SWITCH) kana hub (HUB), uye ichishandisa hafu-duplex modhi, zvinozokonzera kukakavara kwakakomba uye kurasikirwa kwepaketi.
2.Yakaedzwa kuti ibatane nemamwe mafibre optic transceivers?
Parizvino, kune akawanda uye akawanda optical transceivers pamusika.Semuenzaniso, kana kuenderana kwemhando dzakasiyana dzema transceivers kusati kwamboyedzwa, zvinozokonzera kurasikirwa kwepaketi, nguva yekufambisa kwenguva refu, nekukurumidza uye kunonoka.
3.Is pane chigadziro chekuchengetedza kudzivirira kurasikirwa kwepakiti?
Vamwe vanogadzira vanoshandisa rejista data transfer mode kuitira kuderedza mari pakugadzira fiber optic transceivers.Kunyanya kusakosha kweiyi nzira ndeyokuti kutapurirana hakuna kugadzikana uye kurasikirwa kwepakiti, uye yakanakisisa ndeyokushandisa buffer line design, iyo inogona kudzivirira zvakachengeteka data. kurasikirwa kwepakiti.
4.Temperature kuchinjika?
Kana iyo fiber optic transceiver pachayo ikashandiswa, inoburitsa kupisa kwakanyanya.Kana tembiricha yakanyanyisa (kwete kupfuura 50 ° C), kana iyo fiber optic transceiver inoshanda zvakajairika chinhu chakakosha kutariswa nevatengi!
5.Is pane IEEE802.3u chiyero?
Kana iyo transceiver yemaziso inosangana neIEEE802.3 chiyero, kureva kuti, nguva yekunonoka inodzorwa pa46 bits.Kana ikapfuura 46 bits, chinhambwe chinofambiswa neaporivha yemaziso chinozopfupikiswa.
6.After-sales service:
Kuti uite basa rekutengesa mushure mekupindura nekukurumidza uye nekutanga, zvinokurudzirwa kuti vatengi vatenge fiber-optic transceivers maererano nesimba remugadziri, tekinoroji, mukurumbira uye mamwe makambani.
