ULuhlu loLawulo lokuFikelela (ACLs) luluhlu lwemiyalelo olusetyenziswa kujongano lwendlela.Olu luhlu lwemiyalelo lusetyenziselwa ukuxelela i-router ukuba zeziphi iipakethi ezinokufunyanwa kwaye zeziphi iipakethi ezifuna ukwaliwa.Ngokuphathelele ukuba ipakethi ifunyenwe okanye yaliwe, inokumiselwa ...

Uthungelwano lwe-PON lunamacandelo amathathu: i-OLT (ehlala ibekwe kwigumbi lekhompyutha), i-ODN, kunye ne-ONU (ehlala ibekwe kwikhaya lomsebenzisi okanye kwipaseji ekufutshane nomsebenzisi).Phakathi kwazo, inxalenye yemigca kunye nezixhobo ezivela kwi-OLT ukuya kwi-ONU zi-passive, ngoko kuthiwa yi-Passive ...

1, Phambi kokwazisa iFTTR, masiqonde ngokufutshane ukuba yintoni iFTTx.I-FTTx sisishunqulelo se-"Fiber to The x", sibhekisa ku-"fiber ukuya ku-x", apho u-x engameli kuphela indawo apho ifayibha ifika khona, kodwa ikwabandakanya izixhobo zothungelwano lwamehlo ezifakelwe kwi...

Yintoni i-fiber optic transceiver?I-Fiber optic transceivers ziiyunithi ze-Ethernet zothumelo lwemithombo yeendaba ezitshintshisa umgama omfutshane ojijekileyo wemiqondiso yombane kunye nemiqondiso yokubona ekude, eyaziwa ngokuba ziziguquli zefayibha kwiindawo ezininzi.Imveliso gen...

Ukuphuhliswa kwe-Power over Ethernet (POE) iteknoloji yomelele kakhulu.Ukuphuhliswa kobu buchwepheshe kunokwenza lula ukufakwa kunye nokuthunyelwa kwezixhobo zombane, ngaloo ndlela kupheliswe imfuneko yemigca yokuhambisa ngokuzimeleyo.Namhlanje, itekhnoloji yobonelelo lwamandla...

Kungakhathaliseki ukuba yeyiphi indlela esetyenziswayo ukufezekisa unxibelelwano lwezibuko lothungelwano, ayinakohlulwa kwiiprothokholi ezisemgangathweni ezifanelekileyo.Nangona kunjalo, i-Ethernet ebandakanyekayo kuluhlu lweemveliso zenkampani yethu ye-ONU ikakhulu ilandela umgangatho we-IEEE 802.3.Ngezantsi yintshayelelo emfutshane kwi...
