Apa prabédan antarane serat single-mode lan serat multi-mode?
2021-07-16
Serat optik ngirim sinyal liwat guide cahya, non-konduktif, lan ora wedi serangan kilat, supaya ana ora perlu kanggo nggunakake pangayoman grounding. Miturut mode transmisi cahya ing serat optik, kita dibagi dadi serat optik multi-mode lan serat optik single-mode.
Serat multimode: Bisa ngirim macem-macem mode cahya.
Serat mode tunggal: Mung siji mode cahya sing bisa ditularake.
Apa prabédan antarane serat single-mode lan serat multi-mode? Serat single-mode nggunakake laser solid-state minangka sumber cahya; serat multi-mode nggunakake dioda cahya-emitting minangka sumber cahya; serat single-mode wis frekuensi transmisi sudhut lan jarak transmisi dawa, nanging amarga mbutuhake sumber laser, biaya dhuwur; serat multi-mode nduweni kacepetan transmisi kurang lan jarak cendhak , Nanging biaya relatif kurang; siji-mode diameteripun serat inti lan sawur cilik, saéngga mung siji mode transmisi; diameteripun inti serat multi-mode lan sawur gedhe, saéngga atusan mode bisa ditularaké.
