Optical modulation e hoʻohui i ka ʻike i ka nalu māmā lawe, no laila e hoʻololi kekahi ʻāpana o ka nalu māmā me ka hoʻololi ʻana o ka hōʻailona waho, me ka ikaika o ka nalu māmā, ka pae, ka pinepine, ka polarization, ka lōʻihi o ka nalu a pēlā aku.Hoʻouna ʻia ka nalu māmā modulated e lawe ana i ka ʻike i loko o ka fiber, ʻike ʻia e ka mea ʻike kiʻi, a laila demodulate i ka ʻike i koi ʻia.
ʻO ke kumu kino o ka electro-optic modulation ʻo ia ka hopena electro-optic, ʻo ia hoʻi, ma lalo o ka hana a kahi kahua uila i hoʻopili ʻia, e hoʻololi ʻia ka index refractive o kekahi mau kristal, a i ka wā e hele ai ka nalu māmā ma kēia ʻano, e lilo kona mau hiʻohiʻona. e hoopilikia a hoololiia.
Nui nā ʻano electro-optic modulators (EO modulator), hiki ke hoʻokaʻawale ʻia i nā ʻano like ʻole e like me nā kūlana like ʻole.
E like me ke ʻano electrode ʻokoʻa, hiki ke hoʻokaʻawale ʻia ʻo EOM i ka modulator parameter lumped a me ka modulator hawewe hele.
E like me ka ʻokoʻa hawewe alakaʻi, hiki ke hoʻokaʻawale ʻia ʻo EOIM i Msch-Zehnder interference intensity modulator a me directional coupling intensity modulator.
E like me ka pilina ma waena o ke kuhikuhi o ka mālamalama a me ke kuhikuhi o ke kahua uila, hiki ke hoʻokaʻawale ʻia ʻo EOM i nā modulators longitudinal a me nā modulators transverse.ʻO ka longitudinal electro-optic modulator nā mea maikaʻi o ka hana maʻalahi, ka hana paʻa (kūʻokoʻa i ka polarization), ʻaʻohe birefringence kūlohelohe, a me nā mea ʻē aʻe. nui ka poho.
ʻO ka Electro-optical intensity modulator kahi huahana i hoʻohui ʻia e Rofea me nā kuleana waiwai naʻauao kūʻokoʻa.Hoʻohui ka mea hana i ka modulator electro-optical intensity modulator, microwave amplifier a me kāna kaʻa kaʻa kaʻa i hoʻokahi, ʻaʻole ia e hoʻomaʻamaʻa wale i ka hoʻohana ʻana o nā mea hoʻohana, akā hoʻomaikaʻi nui hoʻi i ka hilinaʻi o ka MZ intensity modulator, a hiki ke hāʻawi i nā lawelawe maʻamau e like me nā koi o ka mea hoʻohana.
Hiʻona:
⚫ Haʻahaʻa hoʻokomo poho
⚫ Ka bandwidth hana kiʻekiʻe
⚫ Loaʻa hiki ke hoʻololi ʻia a me ka wahi hana offset
⚫ AC 220V
⚫ Maʻalahi e hoʻohana, ke kumu kukui koho
Noi:
⚫ Pūnaehana modulation waho kiʻekiʻe
⚫ ʻO ke aʻo a me ka ʻōnaehana hōʻike hoʻokolohua
⚫Ka mea hana hōʻailona Optical
⚫Optical RZ, ʻōnaehana NRZ
