    Isifinyezo sezinkinga ezivamile zamaphutha kuma-fiber optic transceivers

    Isikhathi Sokuthumela: Oct-12-2019

    Izinkinga ezihlangabezana nazo ekufakweni nasekusetshenzisweni kwama-fiber optic transceivers

    Isinyathelo 1: Okokuqala, uyabona ukuthi inkomba ye-fiber transceiver noma imodyuli ye-optical kanye nenkomba esontekile yePort port?

    1.Uma inkomba ye-optical port (FX) ye-transceiver ye-transceiver kuvuliwe kanye ne-port ye-Optical Port (FX) ye-B transceiver ayikhanyiswanga, i-transceiver is a transceiver: Ukudluliselwa kwe-Optical I-Port iphuliwe ngoba i-Optical Port (Rx) ye-B Transceiver ayitholi isinali ye-Optical.Other kungenzeka ukuthi kunenkinga yokuxhumeka kwe-transceiver (TX), njengokukhanya I-jumper iphukile.

    2.Uma inkomba ye-Optical Port (FX) ye-transceiver ayikhanyiseli, inqume ukuthi isixhumanisi se-fiber sixhumene nesiphakanyeke. I-fiber jumper ixhunyiwe ngokufana kanti enye iyisiphambano.

    3.Inkomba esontekile (i-TP) ayikhanyi. Sicela uqinisekise ukuthi ikhebula elisontekile linephutha noma lixhunyiwe ngokungalungile. Sicela usebenzise umhloli wokuqhubeka ukuze uhlole.

    Ama-transceivers ama-4.SOME anamachweba amabili we-RJ45: (Tohub) akhombisa ukuthi umugqa wokuxhuma oxhumanisaamaswishiumugqa oqondile. (Toode) kukhombisa ukuthi umugqa wokuxhuma oxhumanisaamaswishii-cross-line.

    5.I-transmitters ine-MPRshintshaohlangothini: umugqa wokuxhuma oxhumanisaamaswishiimodi eqondile ye-lineshintsha: Umugqa wokuxhuma oxhumanisaamaswishiyimodi ye-Cross-line.

    Isinyathelo 2: Hlaziya ukuthi ngabe kunenkinga nge-jumper ye-fiber nentambo?

    I-1.OPTIC Finge Connection Connection On-Off Ukutholwa: Sebenzisa i-Laser Flashlight, ukukhanya kwelanga, njll. Ukukhanyisa i-fiber jumper.see uma kukhona ukukhanya okubonakalayo ngakolunye uhlangothi? Uma kukhona ukukhanya okubonakalayo, i-fiber jumper ayiphukile.

    Ukutholwa kwe-2cable Break: Sebenzisa i-Laser Flashlight, ukukhanya kwelanga, ukukhanyisa ukukhanyisela isixhumi sekhebula noma i-coupler.see uma kukhona ukukhanya okubonakalayo ngakolunye uhlangothi? Uma kunokukhanya okubonakalayo, ikhebula aliphuliwe.

    Isinyathelo 3: Ngabe i-Half / i-duplex yendlela ephelele ayilungile?

    Amanye ama-transceivers ane-FDXamaswishiohlangothini: i-duplex egcwele; I-HDXamaswishi: Half duplex.

    Isinyathelo 4: Kusetshenziswa ukutholwa kwamathuluzi we-Optical Power Meter

    Amandla akhanyayo we-transceiver ye-Optical transceiver noma imodyuli ye-optical ngaphansi kwezimo ezijwayelekile: multimode: -10DB-18DB; Imodi eyodwa 20km: -8DB-15DB; Imodi eyodwa 60km: -5DB-12DB uma amandla akhanyayo we-transceiver ye-optical ephakathi kuka-30db-45DB, khona-ke angahlulelwa ukuthi kunenkinga nale transceiver.

    Transceivers we-Optical kufanele anake izinto

    Ngenxa yokulula, kungcono ukuba ube nombuzo kanye nesitayela sokuphendula, esingatholakala shazi.

    1.I-transceiver ye-optical ngokwayo isekela okugcwele-duplex ne-half-duplex?

    Amanye ama-chips emakethe angasebenzisa kuphela imvelo egcwele egcwele njengamanje, futhi ayikwazi ukusekela uhhafu we-duplex. Uma uxhuma kweminye imikhiqizo yeamaswishi (SHINTSHA) Noma i-HUB (HUB), futhi isebenzisa imodi ye-Half-Dumplex, nakanjani izokwenza izingxabano ezinkulu kanye nokulahleka kwephakethe.

    2.Kukhona yini ukuthi ihlolwe ngokuxhumana nezinye izincwadi ze-fiber optic?

    Njengamanje, kunezinguqulo eziningi ngokwengeziwe ezimakethe. Isibonelo, uma ukuhambisana kwemikhiqizo ehlukene ye-transceivers akuzange kuhlolwe ngaphambili, kuzoholela ekulahlekelweni kwepakethe, isikhathi eside sokuhambisa, kanye nokushesha futhi kuhamba kancane.

    3.Ikhona yini insiza yokuphepha ukuvikela ukulahleka kwepakethe?

    Abanye abakhiqizi basebenzisa irejista yedatha yokudlulisa idatha ukuze banciphise izindleko lapho bekhiqiza ama-transceivers we-fiber optic..Ukungahambi kahle kwale ndlela ukuthi ukulahlwa kwalolu hlelo, futhi okungcono kakhulu ukusebenzisa idatha ephephile ukulahleka kwephakethe.

    4.Izimo eziguqukayo?

    Lapho kusetshenziswa i-fiber optic transceiver uqobo, izokhiqiza ukushisa okuphezulu. Lapho izinga lokushisa liphezulu kakhulu (hhayi ngaphezulu kuka-50 ° C), noma ngabe i-fiber optic transceiver isebenza ngokujwayelekile iyisici esikufanele ukucatshangelwa amakhasimende!

    5.Ikhona okujwayelekile kwe-IEEEE802.3U?

    Uma i-transceiver ye-Optical ihlangana ne-IEEE802.3 ejwayelekile, okungukuthi, ukubambezeleka sekulawulwa ku-46 bits. Uma kudlula izingcezwana ezingama-46, ibanga elidluliswa yi-transceiver ye-optical lizofinyezwa.

    6.Emva kokuthengisa

    Ukuze wenze insizakalo yangemva kokuthengisa iphendule ngokushesha futhi kusenesikhathi, kunconywa ukuthi amakhasimende athenge ama-transceivers we-fiber-optic ngokusho kwamandla womenzi, ubuchwepheshe, idumela kanye nezinye izinkampani.
