Kuyiqiniso elingephikiswe ukuthi ama-optics asetshenziswa kakhulu ezimotweni.Imishini yokubona iqhakaza yonke indawo ezimotweni futhi ihola ikusasa.Kungakhathaliseki ukuthi ukukhanya kwemoto, ukukhanya kwe-ambient yangaphakathi, i-optical imaging, i-LiDAR, noma inethiwekhi ye-fiber optic.
Ukuze uthole isivinini esiphezulu, izimoto zidinga ukudluliswa kwedatha kusuka ku-copper kuya ku-optical physics.Ngenxa yokuhambisana kwayo okungenakuqhathaniswa kwe-electromagnetic, ukwethembeka, kanye nezindleko eziphansi, ukuxhumana kwe-optical Ethernet kukuxazulula kahle ukuphazanyiswa kukagesi kanye nezinselelo ezahlukahlukene zezimoto:
I-EMC: I-Fiber optic empeleni ayinaziphazamiso kazibuthe futhi ayikhiphi ukuphazamiseka, ngaleyo ndlela yonga isikhathi esiningi sokuthuthuka nezindleko.
Izinga lokushisa: Izintambo ze-Fiber optic zingamelana nezinga lokushisa elidlulele elingu- -40 º C kuya ku+125 º C ukuze lisebenze kwemvelo.
Ukusetshenziswa kwamandla: Iziteshi ezilula zivumela ukusetshenziswa kwamandla okuphansi kunethusi, ngenxa ye-DSP/ukulinganisa okulula futhi asikho isidingo sokukhanselwa kwe-echo.
Ukuthembeka/Ukuqina: Ukukhethwa kwe-wavelength engu-980 nm kuqondanisa okokusebenza kwe-VCSEL nokuthembeka kwezimoto nempilo yokuphila.
Izixhumi ezingaphakathi: Ngenxa yokungabikho kwesivikelo, izixhumi zincane futhi ziqine ngokwemishini.
I-overhead yamandla: Uma kuqhathaniswa nekhopha, kufika kwezixhumi ezingu-4 ezisemgqeni ezinesivinini esingu-25 Gb/s2 nezixhumi ezi-2 ezisemgqeni ezinesivinini esingu-50 Gb/s zingafakwa ngaphezu kobude obungamamitha angu-40.Izixhumi ezi-inthanethi ezi-2 kuphela ezingafakwa kusetshenziswa ithusi, ezinobude obuyi-11 m no-25 Gb/s.
Ukusebenza kwezindleko: Idayamitha ephansi ye-OM3 fiber ingafinyelela izinzuzo ezibalulekile zezindleko.Ngokuphambene, ama-copper shielded differential pair (SDP) cores of 25GBASE-T1 are AWG 26 (0.14 mm2) and AWG 24 (0.22 mm2).Njengereferensi, umnyombo wekhebula le-Cat6A uvamise ukuba yi-AWG 23.
