The M107H 1550nm directly modulated optical transmitter supports the DOCSIS 3.1 technology standard. The transmitter can be used in FTTX network architecture and it can be used for the value-added services of TV image signals, digital television signals, telephone voice signals and data signals. DWDM is used to support overlay insertion system. The ITU channel is optional. The RF drive part adopts our own developed RF pre-distortion circuit. The integrated microcomputer automatic monitoring system ensures the unit is working on optimum performance.
Features
l 47 - 1218 MHz RF passband to increase bandwidth capacity for new services
