Izinkinga ezihlangatshezwe ekufakweni nasekusetshenzisweni kwama-transceivers e-fiber optic
Isinyathelo 1: Okokuqala, uyayibona yini ukuthi inkomba ye-fiber transceiver noma imojuli ye-optical kanye nesibonisi sembobo esisontekile sivuliwe?
1.Uma inkomba yembobo yokubona (FX) ye-A transceiver ivuliwe futhi inkomba yembobo yokubona (FX) ye-transceiver engu-B ingakhanyi, iphutha liku-A ohlangothini lwe-transceiver: okunye okungenzeka ukuthi: I-transceiver (TX) i-optical transmission Imbobo iphukile ngenxa yokuthi i-optical port (RX) ye-transceiver B ayitholi isignali yokubona.Okunye okungenzeka ukuthi kunenkinga ngalesi sixhumanisi se-fiber se-A transceiver (TX) optical port, njengesibani. i-jumper iphukile.
2.Uma i-optical port (FX) inkomba ye-transceiver ingakhanyi, nquma ukuthi isixhumanisi se-fiber sixhumene yini.I-fiber jumper ixhunywe ngokuhambisana futhi enye iyi-cross-connect.
3.Isikhombi se-twisted pair (TP) asikhanyi.Sicela wenze isiqiniseko sokuthi ikhebula elisontekile linephutha noma lixhumeke ngokungalungile.Sicela usebenzise isihloli sokuqhubeka ukuhlola.(Kodwa-ke, izinkomba ezithile ezisontekile zama-transceivers kumele zilinde kuze kuvulwe isixhumanisi sefayibha).
I-4.Amanye ama-transceivers anezimbobo ezimbili ze-RJ45: (I-ToHUB) ibonisa ukuthi umugqa wokuxhuma oxhuma ama-switch umugqa oqondile.(I-ToNode) ikhombisa ukuthi ulayini wokuxhuma oxhuma amaswishi uwumugqa onqamulayo.
5.Amanye ama-transmitter ane-MPR switch eceleni: ulayini wokuxhuma oxhuma amaswishi imodi yomugqa oqondile.Iswishi ye-DTE: ulayini wokuxhuma oxhuma amaswishi yimodi ye-cross-line.
Isinyathelo sesi-2: Hlaziya ukuthi ingabe ikhona yini inkinga nge-fiber jumper nekhebula?
1.Ukutholwa kokuxhumeka kwe-fiber ekucishiwe: sebenzisa i-laser flashlight, ukukhanya kwelanga, njll. ukuze ukhanyise i-fiber jumper.Bona ukuthi kukhona ukukhanya okubonakalayo ngakolunye uhlangothi?Uma kukhona ukukhanya okubonakalayo, i-fiber jumper ayiphukile.
2.Ukutholwa kwekhefu lekhebula: sebenzisa ithoshi le-laser, ukukhanya kwelanga, isikhanyisi ukukhanyisa isixhumi sekhebula noma i-coupler.Bona ukuthi kukhona ukukhanya okubonakalayo ngakolunye uhlangothi?Uma kukhona ukukhanya okubonakalayo, ikhebula aliphukile.
Isinyathelo sesi-3: Ingabe indlela ye-duplex enguhhafu/egcwele ayilungile?
Amanye ama-transceivers anokushintsha kwe-FDX ohlangothini: i-duplex egcwele;Ukushintshwa kwe-HDX: i-half duplex.
Isinyathelo sesi-4: Ukusebenzisa ukuthola ithuluzi lemitha yamandla okukhanya
Amandla akhanyayo we-transceiver optical noma imodyuli ye-optical ngaphansi kwezimo ezijwayelekile: i-multimode: -10db-18db;imodi eyodwa 20km: -8db–15db;imodi eyodwa 60km: -5db–12db Uma amandla akhanyayo e-transceiver optical ephakathi kuka -30db–45db, kungase kuthiwe kunenkinga ngale transceiver.
Ama-transceivers optical kufanele anake izinto
Ukuze kube lula, kungcono ukuba nesitayela sombuzo nezimpendulo, esingafinyelelwa ngokubheka nje.
1.Ingabe i-optical transceiver ngokwayo isekela i-full-duplex ne-half-duplex?
Amanye ama-chips emakethe angasebenzisa kuphela indawo ephindwe kabili okwamanje, futhi awakwazi ukusekela i-half-duplex.Uma uxhuma kwezinye izinhlobo zokushintshwa (SWITCH) noma ihabhu (HUB), futhi isebenzisa imodi eyi-half-duplex, nakanjani izobangela ukungqubuzana okukhulu nokulahlekelwa kwephakethe.
2.Ingabe ihlolelwe ukuxhumana namanye ama-fiber optic transceivers?
Njengamanje, kunama-transceiver optical andayo emakethe.Isibonelo, uma ukuhambisana kwezinhlobo ezahlukene zama-transceivers kungakaze kuhlolwe ngaphambilini, kuzophinde kuphumele ekulahlekeni kwephakethe, isikhathi eside sokudlulisa, kanye nokushesha nokuhamba kancane.
3.Ingabe ikhona idivayisi yokuphepha yokuvimbela ukulahleka kwephakethe?
Abanye abakhiqizi basebenzisa imodi yokudlulisa idatha ukuze banciphise izindleko lapho kukhiqizwa ama-transceivers e-fiber optic.Ububi obukhulu bale ndlela ukuthi ukudluliswa akuzinzile futhi ukulahleka kwephakethe, futhi okungcono kakhulu ukusebenzisa idizayini ye-buffer line, engagwema ngokuphephile idatha. ukulahlekelwa kwephakethe.
4.Ukuvumelana nezimo lokushisa?
Lapho i-fiber optic transceiver ngokwayo isetshenziswa, izokhiqiza ukushisa okuphezulu.Uma izinga lokushisa liphezulu kakhulu (hhayi ngaphezu kuka-50 °C), noma ngabe i-fiber optic transceiver isebenza ngokujwayelekile kuyisici okufanele sicatshangelwe amakhasimende!
5.Ingabe likhona izinga le-IEEE802.3u?
Uma i-transceiver ebonakalayo ihlangabezana nezinga le-IEEE802.3, okusho ukuthi, isikhathi sokulibaziseka silawulwa ngamabhithi angu-46.Uma idlula amabhithi angu-46, ibanga elidluliswa i-transceiver ebonakalayo lizofinyezwa.
6.Isevisi yangemuva kokuthengisa:
Ukuze wenze isevisi emva kokuthengisa iphendule ngokushesha futhi kusenesikhathi, kunconywa ukuthi amakhasimende athenge ama-transceivers e-fiber-optic ngokusho kwamandla womkhiqizi, ubuchwepheshe, idumela nezinye izinkampani.
