1. Hoʻokaʻawale ʻoihana kamaʻilio
Wahi a nā ʻano lawelawe kamaʻilio like ʻole, hiki ke hoʻokaʻawale ʻia nā ʻōnaehana kamaʻilio i nā ʻōnaehana kamaʻilio telegraph, nā ʻōnaehana kelepona kelepona, nā ʻōnaehana kamaʻilio ʻikepili, a me nā ʻōnaehana kamaʻilio kiʻi. No ka mea, ʻo ka ʻoihana kelepona kelepona ʻo ia ka mea i hoʻomohala ʻia a kaulana loa, ua hoʻouna pinepine ʻia nā lawelawe kamaʻilio ʻē aʻe ma o ke kelepona kelepona lehulehu, e like me ke kelepona kelepona a me ke kamaʻilio ʻikepili lōʻihi, hiki ke hoʻouna ʻia ma o ke ala kelepona. ʻO ka ʻoihana hoʻohui pūnaewele kamaʻilio kikohoʻe kūpono no ka lawe ʻana i ka ʻike o nā ʻano lawelawe like ʻole.
2. Ka hoʻokaʻawale ʻana i ka modulation
E like me ka hoʻololi ʻana o ka hōʻailona i hoʻouna ʻia i ke kahawai, hiki ke hoʻokaʻawale ʻia ka ʻōnaehana kamaʻilio i kahi ʻōnaehana hoʻoili baseband a me kahi ʻōnaehana hoʻouna bandpass. ʻO ka hoʻouna ʻana i ka baseband ka hoʻouna pololei ʻana i nā hōʻailona unmodulated, e like me nā kelepona kelepona kūloko a me ka hoʻolaha uwea; ʻO ka hoʻouna ʻana i ka bandpass he huaʻōlelo maʻamau no ka hoʻololi ʻana o nā hōʻailona like ʻole. Nui nā ʻano modulation. Papa 1-1 papa inoa i kekahi mau hana modulation ma'amau.
3. Hoʻohālikelike e like me nā hiʻohiʻona hōʻailona
Hoʻokaʻawale ʻia ka ʻōnaehana kamaʻilio i kahi ʻōnaehana kamaʻilio analogue a me kahi ʻōnaehana kamaʻilio kikohoʻe e like me ka hoʻouna ʻia ʻana o kahi hōʻailona analogue a i ʻole kahi hōʻailona kikohoʻe ma ke kahawai.
4. Ka hoʻokaʻawale ʻana o ka medium medium
Wahi a ka media transmission, hiki ke hoʻokaʻawale ʻia nā ʻōnaehana kamaʻilio i ʻelua mau ʻāpana: nā ʻōnaehana kamaʻilio uea a me nā ʻōnaehana kamaʻilio uila. Ke hoʻohana nei ke kamaʻilio uea i nā uea (e like me nā uea ma luna, nā kaula coaxial, nā fiber optical, nā alakaʻi nalu, a me nā mea ʻē aʻe) ma ke ʻano he ala hoʻouna e hoʻopau ai i ke kamaʻilio, e like me ke kelepona kūloko, ke kelepona kelepona, ke kelepona submarine cable, etc. Pono nā hawewe electromagnetic e hele ma ka lewa. Hana ʻia kēia ma o ka hawewe pōkole ionospheric propagation, microwave line-of-sight propagation, a me satellite relay, a me nā mea ʻē aʻe.
5. Hoʻohui pūʻulu hana
Hoʻokaʻawale ʻia nā lako kamaʻilio i ke kamaʻilio hawewe lōʻihi, kamaʻilio hawewe waena, kamaʻilio pōkole pōkole, kamaʻilio mamao-infrared, etc.
6. Hoʻokaʻawale ʻia e ka hōʻailona multiplexing
ʻEkolu mau ʻano hana multiplexing no ka hoʻouna ʻana i nā hōʻailona multiplexed, ʻo ia hoʻi ka hoʻokaʻawale ʻana i ka frequency division multiplexing, ka hoʻokaʻawale ʻana i ka manawa, a me ka code division multiplexing. ʻO ka hoʻohana ʻana i ke ʻano o ka hoʻololi ʻana i ke alapine e hana i nā hōʻailona like ʻole e noho i nā pae alapine like ʻole; ʻO ka hoʻohana ʻana i ke ʻano modulation pulse e hana i nā hōʻailona like ʻole e noho i nā manawa manawa like ʻole; a ʻo ka code division multiplexing ka hoʻohana ʻana i nā code orthogonal e lawe i nā hōʻailona like ʻole. hōʻailona. Hoʻohana ʻia ka hoʻokaʻawale ʻana i ka pinepine ma ke kamaʻilio analogue kuʻuna. Me ka hoʻomohala ʻana o ke kamaʻilio kikohoʻe, ua hoʻohana nui ʻia ka ʻōnaehana kamaʻilio multiplexing time-division. Hoʻohana nui ʻia ka code division multiplexing i ke kamaʻilio pālahalaha ākea a me nā ʻōnaehana kamaʻilio kelepona no ke kamaʻilio lewa. Eia kekahi, aia ka hawewe mahele multiplexing, a me ka mahele mahele multiplexing.
ʻO ka mea ma luna nei ka ʻatikala "Classification of Communication Systems" i lawe ʻia e Shenzhen HDV phoelectron Technology Co., Ltd. manaʻolana kēia ʻatikala hiki ke kōkua iā ʻoe e hoʻonui i kou ʻike. Ma waho aʻe o kēia ʻatikala inā ʻoe e ʻimi nei i kahi ʻoihana mea hana uila fiber optical maikaʻi āu e noʻonoʻo aie pili ana iā mākou.
Shenzhen HDV phoelectron Technology Co., Ltd.ʻo ia ka mea hana nui i nā huahana kamaʻilio. I kēia manawa, uhi nā mea hana i hana ʻia i kamoʻo ONU, moʻo module optical, OLT moʻo, amoʻo transceiver. Hiki iā mākou ke hāʻawi i nā lawelawe kūikawā no nā hiʻohiʻona like ʻole. Aloha oekukakuka.
