GT HT8800 all C band tunable CATV external modulation optical transmitter, is an industry-leading and pioneer product. 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.
A HT8800 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.
The new generation fiber optical communication technology with DWDM nuclear technology should be the NGB's development direction. The DWDM technology can provide large-capacity backbone network and metropolitan area networks for NGB, while PON ( passive optical network ) should be the mainstream technology of NGB subscriber access network.
The DWDM technology can take full advantage of existing fiber optical resource, large-capacity, the network with high flexibility, economic and high reliability. The wavelength can be convertible and management is the DWDM system's core equipment of external modulation optical transmitter.
