Manaʻo ʻia e hoʻohana i ka photodiode mana no nā hoʻokolohua Lab no nā kumu ʻelua. ʻO ka mea mua, ua hōʻoia ʻo controller photodiode i nā ʻano maikaʻi. ʻO ka lua, ʻoi aku ka maʻalahi o ka hoʻoponopono ʻana i ka ikaika o ke kukui hoʻokomo. Inā hoʻohana ʻoe i ka photodiode kūloko o modulator, e ʻoluʻolu e hōʻoia i ka hoʻohālikelike ʻana o ka mana o ka photodiode i ka mana hoʻokomo.
Hāʻawi ʻo Rofea Optoelectronics i kahi laina huahana o nā modulators Electro-optic pāʻoihana, Phase modulators, Intensity modulator, Photodetectors, Laser light source, DFB lasers, Optical amplifiers, EDFA, SLD laser, QPSK modulation, Pulse laser, Light detector, Balanced photodetector, Laser Driver, Optical power ampl, Laser Optical meter ampl mea ike, Laser diode mea hoʻokele, Fiber amplifier. Hāʻawi pū mākou i nā modulators kūikawā he nui no ka hana maʻamau, e like me 1 * 4 array phase modulators, ultra-low Vpi, a me ultra-high extinction ratio modulators, i hoʻohana nui ʻia i nā kulanui a me nā kula.
