HT8800
1550nm CATV External Modulated Fiber Optical Transmitter
Product description
HT8800 all C band tunable 1550nm CATV external modulated fiber optical transmitter. The tunable range of wavelength: 1528.77~1563.86nm, the adjustable wavelength: >35nm. With the traditional ITU standard wavelength ±0.8nm( ±100GHz ) can tunable, is a completely new concept and application ranges.
It including all C band’s useable wavelength, Its database stores 89 ITU standard wavelength channels ( C band 0.4nm gallery interval ). Users can achieve the selection, switch and route etc wavelength management function quickly, accurately. High wavelength accuracy, high wavelength stability, fast tuning rate, perfectly adapt the NGB DWDM system. It’s high wavelength flexibility and replaceability will become the development direction of next generation broadcast television network ( NGB ) external modulation optical transmitter.
