ʻO nā fiber Optical nā ala uea e hoʻouna i nā hōʻailona optical.
Ke kuhikuhi nei mākou i nā hōʻailona uila pono ʻole i ke kahawai e like me ka walaʻau. Hoʻopiʻi ʻia ka walaʻau ma ka ʻōnaehana kamaʻilio ma luna o ka hōʻailona, a aia pū kekahi i ka ʻōnaehana kamaʻilio inā ʻaʻohe hōʻailona hoʻouna, a mau ka walaʻau i ka ʻōnaehana kamaʻilio. Hiki ke ʻike ʻia ka walaʻau e like me ke ʻano o ka hoʻopili ʻana i ke kahawai, i ʻike ʻia hoʻi he hoʻohui hoʻohui, no ka mea ua hoʻokau ʻia ma ka hōʻailona. He mea ʻino ka walaʻau i ka hoʻouna ʻana i ka hōʻailona, hiki iā ia ke hoʻololi i nā hōʻailona analog, hana hewa i nā hōʻailona kikohoʻe, a kaupalena i ka wikiwiki o ka lawe ʻana i ka ʻike.
Wahi a ka hoʻokaʻawale ʻana o nā kumu, hiki ke hoʻokaʻawale ʻia ka walaʻau i ʻelua mau ʻāpana: ka walaʻau kanaka a me ka walaʻau kūlohelohe. Hoʻokumu ʻia ka walaʻau anthropogenic e nā hana kanaka, e like me ka uila mai nā drill uila a me ka uila transientnā hoʻololi, ka uila mai nā ʻōnaehana hoʻā kaʻa, keakea ʻana mai nā kukui fluorescent, a me ka radiation electromagnetic mai nā lekiō a me nā mea hana ʻē aʻe. ʻO ka walaʻau kūlohelohe kekahi ʻano o ka pāhawewe electromagnetic i ke ʻano, e like me ka uila (light-ning), ka lewa lewa, a me ka cosmicnoise mai ka lā a me ka galaxy (galaxy). Eia kekahi, aia kahi leo kūlohelohe koʻikoʻi, ʻo ia hoʻi, ka walaʻau wela. ʻO ka walaʻau wela mai ka neʻe wela o nā electrons ma nā ʻāpana kū'ē āpau. No ka laʻana, hoʻopuka nā uea, nā mea pale, a me nā mea semiconductor i ka walaʻau wela. No laila, aia ka wala'au wela ma nā wahi a pau a hiki ke loa'a i loko o nā mea uila a pau, ke'ole ka mea ma kahi wela thermodynamic OK. I loko o nā ʻāpana kū'ē, e neʻe mau ana nā electrons manuahi ma muli o ko lākou ikehu wela, e hui pū ana me nā ʻāpana ʻē aʻe i ka neʻe ʻana a neʻe like ʻole i ke ala polygonal, ʻo ia hoʻi, ke ʻike ʻia nei e like me ka neʻe Brownian. I ka loaʻa ʻole o nā mana o waho, ua like ka awelika o kēia manawa mai ka neʻe ʻana o Brownian o kēia mau electrons me ka ʻole, akā ua hana ʻia kahi ʻāpana AC. Kapa ʻia kēia ʻāpana AC noise thermal. He ākea loa ka laulā o ka leo wela, ua puʻunaue like ʻia ma kahi kokoke mai ka zero frequency a hiki i 102Hz.
ʻO kēia ʻo Shenzhen HDV phoeletron Technology Ltd. e lawe iā ʻoe e pili ana i ka ʻatikala "noise in the channel", manaʻolana e kōkua iā ʻoe, ʻo Shenzhen HDV phoeletron Technology Ltd.ONUmoʻo, moʻo transceiver,OLTmoʻo, akā ʻo ka hana ʻana i nā moʻo module, e like me: Communication optical module, optical communication module, network optical module, communication optical module, optical fiber module, Ethernet optical fiber module, etc., hiki ke hāʻawi i ka lawelawe kūpono kūpono no nā mea hoʻohana like ʻole. ' pono, aloha mai i kou kipa 'ana.
