Ngu Admin / 03 Mar 21 /0Amagqabantshintshi Kufuneka ndenze ntoni ukuba ubushushu bemodyuli ye-optical buphezulu kakhulu? Indlela yokusombulula? Imodyuli ye-optical sisixhobo esibonakalayo esibuthathaka. Xa ukushisa okusebenzayo kwemodyuli ye-optical kuphezulu kakhulu, kuya kubangela iingxaki ezifana nokugqithiswa kwamandla optical transmit, impazamo yesignali efunyenweyo, ukulahleka kwepakethi, njl., kunye nokutshisa imodyuli ye-optical ngqo kwiimeko ezinzima. Ukuba t...
