Ni irihe tandukaniro riri hagati ya 50 ohm na 75 ohm coaxial kabel?

Umugozi wa 50 is ukoreshwa cyane cyane mu kohereza amakuru mu buryo bubiri bwo gutumanaho.Imirima yayo ikoreshwa ni nini cyane, harimo gupima ibimenyetso, umuyoboro wa mudasobwa ya Ethernet, umugozi wa antenne utagabanije, GPS yisi yose ya satani ya antenna igaburira hamwe na sisitemu ya terefone igendanwa.Umugozi wa 75 Ω ukoreshwa cyane cyane mu kohereza ibimenyetso bya videwo.Kohereza ibimenyetso bya TV ukoresheje insinga ni porogaramu isanzwe.Muri iki gihe, F-ihuza abahuza bakunze gukoreshwa, nka tereviziyo yo murugo ya tereviziyo ya tereviziyo.Ubundi porogaramu ni kohereza ubutumwa bwa videwo hagati ya DVD ikina DVD, VCR, gukurikirana umutekano nizindi sisitemu nibikoresho.Muri iki gihe, mubisanzwe byitwa amajwi / amashusho (A / V) umugozi nuhuza.Muri iki gihe, abahuza BNC na RCA bakunze gukoreshwa.75 Ω insinga mubisanzwe ni umugozi ukomeye wa RG59B / U hamwe numuyoboro wa kaburimbo rwagati RG59A / U.75 Ω umugozi ukoreshwa cyane cyane mugukwirakwiza ibimenyetso bya videwo, mugihe 50 Ω umugozi ukoreshwa cyane cyane mugukwirakwiza amakuru.
