Ulwakhiwo lweMveliso
1. Isakhiwo se-AOC se-100G ikhebula le-optical esebenzayo
Intambo ye-optical esebenzayo iqulethwe ngama-transceiver optical fiber kunye ne-jumper eyodwa ye-optical cable.Iqulethwe ngama-transceivers optical fiber kuzo zombini iziphelo kunye neentlobo ezahlukeneyo zefiber optical OM3 kunye ne-OM4 i-multimode optical fiber.
2. I-100G isakhiwo se-DAC esinesantya esiphezulu sobhedu
Iintambo zobhedu ezinesantya esiphezulu zinokwahlulwa zibe ziintambo zobhedu ezinesantya esiphezulu kunye neentambo zobhedu ezisebenzayo ezinesantya esiphezulu.Intambo yobhedu esebenzayo enesantya esiphezulu ine-chip enye ngaphezulu kunentambo yobhedu enesantya esiphezulu."Iimodyuli ze-optical" kuzo zombini iziphelo ze-DAC yobhedu enesantya esiphezulu azikho iimodyuli zangempela zamehlo.Azinawo amacandelo kwaye zinokudlulisela kuphela imiqondiso yombane.Ke ngoko, iDAC yobhedu enesantya esiphezulu inexabiso eliphantsi kunezinye izixhobo eziqhelekileyo zokukhanya.Nangona i-port efanayo isetyenziswe njenge-interface yemodyuli yefiber, ikhebula le-copper high-speed lingagcina iindleko kunye nokunciphisa ukusetyenziswa kwamandla kwizicelo ezikude.Kungenxa yoko le nto abantu bekhetha iintambo zobhedu ezinesantya esiphezulu.I-DAC ye-high-speed copper, exhunywe kwiiswitshi okanye iiseva kuzo zombini iziphelo, ivumela ukuhanjiswa kwexesha elifutshane.
