Solution Description
Product Description
GT HT8800 all C band tunable CATV external modulation optical transmitter, is an sector-major and pioneer merchandise. The tunable assortment of wavelength: 1528.seventy seven~1563.86nm, the adjustable wavelength: >35nm. With the conventional ITU standard wavelength ±0.8nm( ±100GHz ) can tunable, is a completely new notion and application ranges.
A HT8800 such as all C band’s useable wavelength, Its databases stores 89 ITU normal wavelength channels ( C band .4nm gallery interval ). Users can attain the choice, switch and route and so on wavelength administration purpose speedily, properly. CZPT wavelength accuracy, higher wavelength steadiness, CZPT tuning charge, perfectly adapt the NGB DWDM program. It really is higher wavelength overall flexibility and replaceability will grow to be the advancement route of following generation broadcast tv network ( NGB ) exterior modulation optical transmitter.
The new era fiber optical interaction engineering with DWDM nuclear technology ought to be the NGB’s improvement route. The DWDM technology can provide massive-capability backbone network and metropolitan location networks for NGB, while PON ( passive optical community ) should be the mainstream technology of NGB subscriber access network.
The DWDM technologies can consider complete advantage of present fiber optical source, massive-potential, the community with large adaptability, economic and high reliability. The wavelength can be convertible and management is the DWDM system’s core tools of exterior modulation optical transmitter.
