10mw Standard 1550nm ITU standard wavelength Direct Modulated optical transmitter

1550nm ITU standard wavelength Direct Modulated optical transmitter 10mw Standard

1550nm intelligent directly modulated optical transmitter, mainly used in 1550nm optical fiber transmission system is the most important equipment to construct the CATV network. It mainly used for the value-added services of TV image signal, digital television signal, telephone voice signal and data (or compressed data) signal. By built-in WDM, multiplex the inter-cut optical signal and the main optical signal then output. After setting required optical difference, the perfect adjustable optical attenuation function can automatically control the inserted optical signal according to the main optical signal, realize inter-cut system full automatic adjustment. Provide high quality low cost solution for all-optical relay 1550 optical fiber CATV system, and local value-added services inter-cut.
