Teleste - HDO773 C-BAND DWDM FIBRE TRANSMITTER

HDO773 is a high performance directly modulated C-band DWDM transmitter

for forward path fibre optic links in CATV and FTTx networks. HDO773 is able to carry all kind of analog or/ and digital channel loading on the whole frequency band. HDO773 transmitter contains an electrical dispersion compensator that is important especially when analog channels are transmitted to longer distances. HDO773 is installed into a HDX installation frame and the transmitter is available on different optical wavelengths in accordance with the ITU wavelength grid. HDO773 has two equal input sections with level and slope adjustments to support broadcast and narrowcast signal distribution. The RF isolation between the input branches is high minimising the leakage of narrowcast signals into unwanted narrowcast node segments. The power consumption is low but HDO773 still offers the high performance and the widest variety of features.
