Ìhè bụ ụdị ebili mmiri elektrọnik nwere ugboro dị elu. O nwere njikọ dị mma, ya mere, dịka ebili mmiri elektrọnik gara aga (dịka redio na telivishọn), enwere ike iji ya dị ka ihe na-ebu ozi. A na-eziga ozi "nke" leza ahụ "na-ebu" (gụnyere asụsụ, ederede, onyonyo, akara, wdg.) na onye na-anabata ya site na ọwa nnyefe ụfọdụ (ikuku, eriri anya, wdg), wee chọpụta ma weghachite ya na ozi mbụ site na onye na-anabata optical. A na-akpọ usoro nke itinye ozi na leza modulation, a na-akpọkwa ngwaọrụ nke na-emezu usoro a modulator. N'ime ha, a na-akpọ leza ahụ ebili mmiri ebu; A na-akpọ ozi ugboro ole na ole dị ala nke na-arụ ọrụ njikwa akara modulated.

Enwere ike kewaa nhazi laser n'ime modulation na modulation mpụga.

Mgbanwe ime: Ọ na-ezo aka na ibu nke mgbaama ndị agbanwere agbanwe n'oge usoro mmegharị laser, ya bụ, iji mgbaama ndị agbanwere agbanwe iji gbanwee paramita oscillation nke laser, si otú a na-agbanwe njirimara mmepụta laser iji nweta mgbanwe. Ụzọ nke mgbanwe ime gụnyere: 1. Ijikwa ọkụ eletrik laser ozugbo iji nweta ike nke laser mmepụta agbanwere agbanwe. Ike na ọnụnọ nke mmepụta niile bụ nke ọkụ eletrik na-achịkwa. Ọ bụrụ na ejiri mgbaama a ga-ebufe achịkwa ọkụ eletrik laser, na-eme mgbanwe ugbu a site na laser nke mgbaama ahụ na-achịkwa, mgbe ahụ, a ga-ejikwa mgbaama ahụ achịkwa laser ewepụtara. 2. A na-etinye ihe ndị na-agbanwe agbanwe n'ime oghere resonant, a na-ejikwa ihe ndị dị na ihe ndị na-agbanwe agbanwe achịkwa site na mgbaama iji gbanwee, si otú a na-agbanwe paramita nke oghere resonant ma na-agbanwe njirimara mmepụta laser iji nweta mgbanwe. Uru nke mgbanwe ime bụ arụmọrụ modulation dị elu ya. Ihe na-akpata ya bụ na ebe ọ bụ na e tinyere modulator n'ime oghere ahụ, ọ dị ka ịbawanye mfu n'ime oghere ahụ, na-ebelata ike mmepụta, na oke bandwit nke modulator ahụ na-ejedebe site na pasband nke oghere resonant.

Mgbanwe Mpụga: Ọ na-ezo aka n'itinye modulator n'okporo ụzọ anya dị n'èzí laser mgbe e guzobere laser ahụ, a na-agbanwekwa njirimara anụ ahụ nke modulator site na mgbaàmà mgbanwe. Mgbe laser gafere na modulator ahụ, a ga-agbanwe paramita ụfọdụ nke ebili mmiri ọkụ. Uru nke mgbanwe mpụta bụ na ọ naghị emetụta ike mmepụta nke laser ahụ na bandwit nke generator anaghị ejedebe site na pasband nke oghere resonant. Ihe na-akpata ya bụ arụmọrụ modulation dị ala.
