Yintoni esebenzayo (AON) kunye ne-passive (PON) inethiwekhi ye-optical network?
Yintoni i-AON? I-AON yinethiwekhi ye-optical esebenzayo, ngokuyininzi ithatha i-point-to-point (PTP) i-architecture yenethiwekhi, kwaye umsebenzisi ngamnye unokuba nomgca we-fiber optical ozinikeleyo. Inethiwekhi ye-optical esebenzayo ibhekiselele ekusasazweni kwee-router, ii-aggregators zokutshintsha, izixhobo ezisebenzayo kunye nezinye izixhobo zokutshintsha...Funda ngokugqithisileyo - Ngu Admin / 23 Jul 20 /0Amagqabantshintshi
Umgaqo wokusebenza kunye nokusetyenziswa kwemodyuli ye-optical transmission optical
Kwinkalo yonxibelelwano, uthungelwano lombane lonxibelelwano lweengcingo zentsimbi luthintelwe kakhulu ngenxa yezinto ezinjengokuphazamiseka kombane, i-inter-code crosstalk kunye nelahleko, kunye neendleko zocingo. Ngenxa yoko, ukuhanjiswa kwamehlo kwazalwa. Ukuhanjiswa kwamehlo kunoncedo lwe ...Funda ngokugqithisileyo - Ngu Admin / 21 Jul 20 /0Amagqabantshintshi
Intshayelelo kunye nokusetyenziswa kwe-EPON imodyuli ye-optical kunye ne-GPON yemodyuli yokubona
I-PON ibhekisa kuthungelwano lwefiber optical passive, eyindlela ebalulekileyo yokufikelela kwiinkonzo zothungelwano olubanzi ekufuneka luqhutywe. I-teknoloji ye-PON yavela kwi-1995. Kamva, ngokomahluko phakathi kwedatha yekhonkco yedatha kunye nomgangatho womzimba, iteknoloji ye-PON yahlulwa ngokuthe ngcembe kwi-APON ...Funda ngokugqithisileyo - Ngu Admin / 17 Jul 20 /0Amagqabantshintshi
Yintoni i-optical fiber? Iimpawu kunye nokuhlelwa kwefiber optical
Ifayibha ye-Optical ihambisa imiqondiso ngendlela yee-pulses ezikhanyayo, kwaye isebenzisa iglasi okanye i-plexiglass njengendlela yokuhambisa inethiwekhi. Iqukethe i-fiber core, i-cladding kunye nesigqubuthelo sokukhusela. Ifayibha ye-Optical inokohlulwa ibe yifayibha yeNdlela enye kunye neFibre yeModi eNinzi. Ifayibha ye-optical yemowudi enye ingqina kuphela...Funda ngokugqithisileyo - Ngu Admin / 14 Jul 20 /0Amagqabantshintshi
Ukuqonda ngokukhawuleza i-FTTx FTTC FTTB FTTH
Yintoni FTTx? I-FTTx yi "Fiber To The x" kwaye ligama eliqhelekileyo lokufikelela kwifayibha kunxibelelwano lwefiber optic. x imele indawo yomgca wefiber. Enjenge-x = H (IFayibha ukuya eKhaya), x = O (Ifayibha kwi-Ofisi), x = B (IFayibha kwiSakhiwo). Itekhnoloji yeFTTx iqala...Funda ngokugqithisileyo - Ngu Admin / 10 Jul 20 /0Amagqabantshintshi
Ngaba iimodyuli ezibonakalayo ze-SFP zingasetyenziswa kwiindawo zokubeka i-SFP+?
Iimodyuli ze-SFP ezibonakalayo zinokufakwa kwizibuko ze-SFP + kwiimeko ezininzi. Nangona imodeli ethile yokutshintsha ayiqinisekanga, ngokuhambelana namava, iimodyuli ze-SFP optical zingasebenza kwi-SFP + slots, kodwa iimodyuli ze-SFP + optical azikwazi ukusebenza kwii-slots ze-SFP. Xa ufaka imodyuli ye-SFP kwizibuko le-SFP+, i-spe...Funda ngokugqithisileyo
