Compact and slim space-saving design! QAM method modem unit.
The "QM08A" is a four-wire full-duplex/two-wire half-duplex communication modem unit that complies with ITU-T Recommendation V.29 using QAM (Quadrature Amplitude Modulation) technology. The modulation and demodulation core is implemented using FPGA without dedicated LSI, reducing the risk of discontinuation. Additionally, it is a completely newly designed product manufactured domestically, ensuring reliability. It is RoHS compliant. 【Features】 ■ Four-wire full-duplex/two-wire half-duplex synchronous modem ■ Compact and slim space-saving design ■ Loopback diagnostics for both the local unit and the opposing device in opposing communication connections ■ Built-in self-test function that allows for error rate testing of the modem, including the line *For more details, please refer to the PDF document or feel free to contact us.
