Hi Friends,
Today i will try to share the main difference between the OTN( Optical Transport network) and SDH .
From the starting phase of my career i have seen SDH and SONET deployment in huge numbers in with lots of single parenting and double parenting Ethernet rings in operator networks.
The main difference between them apart from the OSI layer compatibilty is in the framing. ( Frame we can assume a payload unit here ).
Usually we have three basis things in terms of the speed and channel capacity enhancement.
1. Frames/sec.
2 Frame period .
3. Frame size.
So capacity depend on as = No of frames/sec * Frame Size ( will give data transmitted).
In case of SDH we cant change the NO of frames /sec as this is TDM technology but we can change Frame size ( Increase frame size increase capacity).
But in case of OTN we cant change the Frame size but we can change the No of frames per second ( Increased capacity as no of frames in a sec increases).

Hi Rishabh,
ReplyDeleteThis doubling the sampling rate is part of Nyquist Thm...Right??
Also, it would be good if you can throw some light on PCM Modulation, Quantization, etch which is basic part for understanding Transport fundamentals.
