Solution Description

Item Description

GT HT8800 all C band tunable CATV exterior modulation optical transmitter, is an market-major and pioneer product. The tunable assortment of wavelength: 1528.77~1563.86nm, the adjustable wavelength: >35nm. With the traditional ITU standard wavelength ±0.8nm( ±100GHz ) can tunable, is a totally new notion and software ranges.
A HT8800 including all C band’s useable wavelength, Its database stores 89 ITU standard wavelength channels ( C band .4nm gallery interval ). End users can accomplish the variety, swap and route and so on wavelength administration function rapidly, correctly. CZPT wavelength accuracy, large wavelength stability, CZPT tuning rate, properly adapt the NGB DWDM system. It is large wavelength overall flexibility and replaceability will turn out to be the advancement direction of subsequent generation broadcast television community ( NGB ) external modulation optical transmitter.
The new era fiber optical conversation technology with DWDM nuclear technological innovation need to be the NGB’s improvement direction. The DWDM engineering can give massive-capacity backbone network and metropolitan area networks for NGB, while PON ( passive optical network ) ought to be the mainstream technology of NGB subscriber obtain community.
The DWDM engineering can get complete edge of present fiber optical resource, huge-capacity, the network with higher overall flexibility, economic and large trustworthiness. The wavelength can be convertible and management is the DWDM system’s main equipment of exterior modulation optical transmitter.
