Overview
MXT-OR-860LH-Ⅰ series field optical receiver is a kind of NEW CATV network products. It adopts the combination of module amplification circuit and GaAs MMIC amplification circuit to optimize the line design to make the machine output with higher performance index when input is in -8～+2dBm. Output designed with adjustable attenuator and equalizer can make CATV network subject very convenient to debug. At mean time to transmit digital and analogue signal, it is the priority in current HFC, EPON network system construction.
Features
