Uburyo bwibanze bwa binary modulisiyo ni:Urufunguzo rwa amplitude urufunguzo (2ASK) - ihinduka ryerekana ibimenyetso byabatwara; Binary frequency shift urufunguzo (2FSK) - guhinduka inshuro yikimenyetso cyabatwara; Icyiciro cya kabiri cyo guhinduranya urufunguzo (2PSK) - ihinduka ryibice byikimenyetso. Urufunguzo rutandukanye rwo guhinduranya (DPSK) rwakozwe kubera ko icyiciro cya sisitemu ya 2PSK kitari kizwi.
2ASK na 2PSK byombi bikenera inshuro ebyiri ubwinshi bwikigereranyo cyikigereranyo, mugihe 2FSK ikenera umurongo mwinshi kuruta 2ASK na 2PSK.
Igipimo cyamakosa ya sisitemu ya binary sisitemu itandukanye iterwa no kwinjiza ibimenyetso-by-urusaku r r ya demodulator. Kubijyanye na anti-additive Gaussian urusaku rwera, coherent 2PSK ifite imikorere myiza, ikurikirwa na 2FSK, naho 2ASK ni mbi cyane.
Baza ni bumwe muburyo bwambere bwo guhindura ibintu. Ibyiza byayo nuko ikoresha bande yumurongo mwinshi kandi ifite ibikoresho byoroshye. Ibibi byayo ni uko atari byokora neza urwanya urusaku kandi yunvikana nimpinduka mubiranga umuyoboro, ibyo bigatuma bigora kubona uwatoranije icyitegererezo kugirango akore muburyo bwiza bwo gufata ibyemezo.
FSK nuburyo bwingirakamaro bwo guhindura muburyo bwitumanaho. Akarusho kayo nuko ifite ubushobozi bukomeye bwo kurwanya-interineti kandi ntibiterwa no guhindura ibipimo byumuyoboro, FSK rero irakwiriye cyane cyane kumiyoboro igenda ishira; Ingaruka ni uko bande yigaruriwe ari nini, cyane cyane kuri mf-sk, kandi gukoresha bande ni bike. Kugeza ubu, sisitemu ya FM ikoreshwa cyane cyane mu kohereza amakuru yo hagati kandi yihuta.
PSK cyangwa DPSK nuburyo bwo guhindura hamwe nuburyo bwiza bwo kohereza. Ubushobozi bwayo bwo kurwanya urusaku burakomeye kuruta ubwa ASK na FSK, kandi ntibworoshye guhinduka nimpinduka ziranga umuyoboro. Kubwibyo, yakoreshejwe cyane murwego rwo hejuru kandi rwihuta rwohereza amakuru. Guhindura icyiciro cyuzuye (PSK) gifite ikibazo cyicyiciro cyabatwara kidasobanutse muri demherent demodulation, idakunze gukoreshwa mugukwirakwiza mu buryo butaziguye mu bikorwa. MDPSK ikoreshwa cyane.
Ibyavuzwe haruguru ni ingingo “Binary digital modulation,” yazanwe na Shenzhen HDV photoelectric Technology Co., Ltd. Ibicuruzwa byitumanaho byakozwe na sosiyete:
Ibyiciro by'amasomo: moderi ya fibre optique, Ethernet, optique fibre transceiver modules, optique ya fibre optique, SSFP optique module, naSFP optique, n'ibindi.
ONUicyiciro: EPON ONU, AC ONU, fibre optique ONU, CATV ONU, GPON ONU, XPON ONU, n'ibindi.
OLTicyiciro: OLT, GPON OLT, EPON OLT, itumanahoOLT, n'ibindi.
Ibicuruzwa byavuzwe haruguru birashobora gutanga inkunga kubintu bitandukanye byurusobe. Itsinda ryumwuga kandi rikomeye R&D rirashobora gufasha abakiriya bafite ibibazo bya tekiniki, kandi itsinda ryubucuruzi ryatekereje kandi ryumwuga rirashobora gufasha abakiriya kubona serivise nziza mugihe cyo kubanza kugisha inama no gukora nyuma yumusaruro. Murakaza neza kuritwandikirekubibazo byose.
