Imiraba yumucyo ni imirasire ya electromagnetique itangwa na electron mugikorwa cya atome. Imyitwarire ya electron muri atome yibintu bitandukanye iratandukanye, bityo imiraba yumucyo basohora nayo iratandukanye.
Spectrum nicyitegererezo cyumucyo umwe utandukanijwe na sisitemu yo gutatanya (nka prism na grating) nyuma yumucyo wa polyikromatike utandukanijwe na sisitemu yo gutatanya, itunganijwe muburyo ukurikije uburebure bwumuraba (cyangwa inshuro). Yitwa optique ya optique yuzuye.
Mugihe cyo kugerageza transmitter tosa, mubisanzwe dushyiramo ibipimo, SMSR (Igipimo cyo Kuruhande Kuruhande). Ikigereranyo cyagaciro ntarengwa cyuburyo bwimbaraga zingenzi kuruhande rwuburyo bwimbaraga byitwa kuruhande rwuburyo bwo guhagarika igipimo, nikimenyetso cyingenzi cyerekana imikorere miremire. Mubisanzwe, mugihe upimye igipimo cyo kwangwa kuruhande, bigomba gukoreshwa hamwe na marikeri hamwe nisesengura mubisesengura. Uwabikoze akoreshwa kugirango amenye impinga yo hagati hamwe nimpinga ndende ya kabiri. Soma impinga ebyiri. Ikigereranyo cyuburyo bwo kwangwa ni itandukaniro ryingufu zingana hagati yimpinga zombi. Irashobora kubarwa binyuze muburyo bwo gusesengura.
Byasobanuwe nkigipimo cyibanze cyibanze cyigihe kirekire optique imbaraga M1 hamwe nuburyo bwuzuye bwa optique imbaraga M2 muburyo bwo guhindura byuzuye.
Inzira yo kubara ni:
SMSR = 10 * lg (M1 / M2)
Muri transmitter optique, muri rusange biragaragara ko SMSR irenze 30dB; ni ukuvuga, imbaraga za optique yuburyo bwibanze bwa longitudinal burenze inshuro 1000 inshuro ntarengwa yuburyo bwa optique imbaraga. Kurenza agaciro ka SMSR, niko kwibanda kumurongo. Nkuko bigaragara ku gishushanyo gikurikira: SMSR ni 51dB
Ibyavuzwe haruguru ni ibisobanuro byubumenyi bwa Lightwave bwazanywe na Shenzhen HDV Phoelectron Technology Co., Ltd., uruganda rukora itumanaho rukora kandi rukora uruganda rukora ibicuruzwa byitumanaho. Murakaza neza kugirango dusure ibyacuurupapuro rwibicuruzwa. Urakoze gusoma iyi ngingo.
