Product Description
WT-1550-DM intelligent directly modulated optical transmitter is mainly used in
1550nm optical fiber transmission system. Adopt advanced electronic dispersion
compensation technology, accurately compensate according to the actual transmission
distance by 1km stepping. The maximum compensated distance up to 50km.
WT-1550-DM intelligent directly modulated optical transmitter 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 automatic 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.
