Kutheni iimodyuli ezibonakalayo ze-SFP zithandwa?

Umthamo weImodyuli yokubona ye-SFPiyancipha ngesiqingatha xa kuthelekiswa nomthamo wemodyuli ye-GBIC optical. Inani leezibuko ze-SFP kwiqela elinye liya kuba kabini kwimodyuli ye-GBIC optical. Imodyuli efanayo ye-SFP ye-optical module ine-plug-and-play mini optical fibre slot, ehambelana nedatha Ngeemfuno eziphezulu zoxinaniso kwiziko, iimodyuli ze-SFP optical ziya kuthatha indawo ye-GBIC optical modules kumaziko edatha kwixesha elizayo.

Iimodyuli ezibonakalayo ze-SFP ezidumileyo

Ngenxa yokuba iimodyuli ze-SFP ze-GLC-BX-D kunye ne-GLC-BX-U zinamandla kwaye zifunwa kakhulu, ezi ntlobo zimbini zeemodyuli ze-optical zixhasa ukubekwa esweni kwedatha yedatha, evumela abasebenzisi ukuba babeke iliso ekusebenzeni kweemodyuli ze-optical ngexesha langempela, njenge. iqondo lobushushu lokulandela umkhondo, ukukhanya Amandla okukhutshwa, amandla okufakwayo optical, i-laser bias current, i-transceiver power supply voltage, njl. I-1000BASE-BX10-D imodyuli ye-SFP ye-optical kunye nomgama wokudluliselwa kwe-10km, imodyuli ye-GLC-BX40-D ye-SFP ye-SFP kunye nomgama wokudluliselwa kwe-40km, kunye nemodyuli ye-GLC-BX80-D ye-SFP ye-optical kunye nomgama wokuhambisa we-80km nayo iyathandwa. phakathi kwabasebenzisi.

Imodyuli yokubona ye-SFP inezi nzuzo zine zilandelayo:

1. Ixhasa ukutshintshwa okushushu, okunokunciphisa ukufakela, ukugcinwa kunye nexesha lokulawula;

2. Izibuko liyaguquguquka;

3. Uyilo olomeleleyo lukhulisa ukuthembeka;

4. Ukuxhasa umsebenzi wokubeka iliso kwidijithali (DOM).

Ukusetyenziswa kwemodyuli yokukhanya ye-SFP

1. Iintambo zomgama omfutshane womnatha I-1000BASE-T Imodyuli ye-SFP ye-optical isekela i-10 / 100 / 1000 i-adaptive kunye ne-Auto MDI / MDIX, kwaye ingasetyenziswa kunye nodidi lwe-5 yeentambo ze-patch network ezingakhuselekanga; umgama wothumelo ungafikelela kwi-100m. I-modyuli ye-1000BASE-SX ye-SFP ye-optical ihambelana ne-IEEE 802.3z 1000BASE-SX esemgangathweni, kwaye ingasetyenziselwa i-50μm / 62.5μm ikhonkco ye-multimode yefiber kunye nomgama ophezulu wokuhanjiswa kwe-550m.

2. Iingcingo zenethiwekhi ezikude I-1000BASE-EX kunye ne-1000BASE-ZX iimodyuli ze-SFP ze-optical zingasetyenziselwa kunye ne-fiber optical mode enye kwaye ifanelekile ukuhanjiswa kwenethiwekhi yomgama omde. Umgama wokudluliselwa kwe-1000BASE-EX SFP iimodyuli ze-optical zingafikelela kwi-40km, kwaye umgama wokuhambisa i-1000BASE-ZX SFP iimodyuli ze-optical zingafikelela kwi-80km.

Qaphela: Xa i-fiber ye-single-mode (i-SMF) isetyenziselwa umgama omfutshane, ukwenzela ukuphepha ukugqithiswa kommkeli, i-optical attenuator kufuneka ifakwe kwikhonkco. Emva kokungeniswa kweprogram engentla, ngaba ufumanisa ukuba i-port ye-SFP inokuxhasa zombini iimodyuli ze-SFP zombane kunye neemodyuli ze-SFP optical port? Kungakhathaliseki ukuba izibuko ze-SFP kunye neemodyuli ze-SFP ezibonakalayo zinokuguquguquka okuphezulu kunye nokuhambelana kwizicelo eziphathekayo, Isisombululo sakho esona sisisombululo seGigabit Ethernet.
