SIAE product portfolio
Two “PDH” and “SDH” segments are merged into one with the advent of the IP Networks.SIAE in the past was proposing different solutions for different application segments; now, it’s proposing one single solution for those two segments.The SDH Trunk section will be more and more covered by optical fiber, by continuous capacity increases.
Dual Native approach chosen and designed by SIAE MICROELETTRONICA achieve the native transmission of both, TDM and Ethernet traffic, in a really flexible way and having some significant advantages if compared with other transport architecture like:- Ethernet over TDM (Multilink-PPP): comparison in following two slidesTDM over Ethernet (PWE3): comparison in slides 40&41Of course, if no TDM is requested, it can be completely disable and thus the radio configuration is totally and definitely FULL IP!
The S/N required by previous radio generations for 4QAM@10-6 was around 11dB. With our solution, WITH THE SAME INFRASTRUCTURES, we can have 50% more capacity.
