• Hāʻawi i ʻekolu manaʻo no ka IQ modulators Modulation format kūʻokoʻa:
•QPSK, QAM, OFDM, SSB hōʻoia
• Hoʻopili a pāʻani:
ʻAʻole pono ka calibration manual
• Nā lima I, Q: hoʻomalu i nā ʻano Peak a me Null Lakiō hoʻopau kiʻekiʻe: 50dB max1
•P lima: ka hoomalu ana ma Q+ a me Q- Ka pololei: ± 2◦
•Kuhi haʻahaʻa: 40mm(W) × 28mm(D) × 8mm(H)
• Paʻa kiʻekiʻe: hoʻokō kikohoʻe piha Maʻalahi e hoʻohana:
• Ka hana lima me ka mini jumper Hoʻololi OEM hana ma o UART2
• ʻElua mau ʻano no ka hāʻawi ʻana i nā volt bias: a.Automatic Bias Control b.User definition bias voltage

2Hoʻokahi wale nō koho e koho ʻia ma waena o ka hoʻohana ʻana i ka photodiode controller a i ʻole ka hoʻohana ʻana i ka photodiode modulator. 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.
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.
