Molaoli oa Leeme oa Ultra Compact DP-IQ Modulator
Tšobotsi
•Ka nako e le 'ngoe e fana ka li-voltage tse tšeletseng tsa bias tse iketsang bakeng sa li-modulator tsa Dual Polarization IQ
• Sebopeho sa modulation se ikemetse:
SSB, QPSK, QAM, OFDM e netefalitsoe.
• Kenya 'me u bapale:
Ha ho hlokahale tlhahlobo ea letsoho Ntho e 'ngoe le e 'ngoe e iketsahalla
•I, Q matsoho: taolo hodima mekhoa ya Peak le Null Tekanyo e phahameng ya ho fela:50dB max1
•Letsoho la P: taolo hodima mekhoa ya Q+ le Q- Ho nepahala: ± 2◦
•Boemo bo tlase: 40mm(W) × 29mm(D) × 8mm(H)
•Botsitso bo phahameng: ho kenya tshebetsong ka botlalo ka dijithale Ho bonolo ho e sebedisa:
•Ts'ebetso ea letsoho ka jumper e nyane ea 2
Ts'ebetso e feto-fetohang ea OEM ka UART / IO
•Mekhoa e 'meli ea ho fana ka li-voltage tsa leeme: a. Taolo ea Leeme e Iketsang b. Leeme la leeme le hlalositsoeng ke mosebelisi
