PDH vs SDH | difference between PDH and SDH

In SDHdigital multiplexer’s inputs are of same bit rate and are derived from common clock, hence are in phase. Rates sdh and pdh pdf download from 2. Following are the limitations of PDH: In PDH pdt, digital multiplexer’s inputs bit streams are of same bit rate and are derived from different clocks from different oscillators.

The different hierarchies having different bit rates are combined. Hence snd and de-multiplexing is very complex.

It employs both electrical and optical specifications. As PDH was not scalable to support high capacity bandwidth sdh and pdh pdf download hence was not suitable to accomodate growing traffic need. Bit Interleaving is used in PDH to combine digital signals. Rates derived from 1. Each will differ within tolerance of few clock periods. Hence multiplexing and de-multiplexing is very complex. Hence it is synchronous. It employs both electrical and optical specifications.

Basic Pdj rate of Following are the merits or advantages of SDH: Hence it is called plesiochronous. SDH supports various topologies such as point to point, ring, star, linear bus etc. In PDH there are sdh and pdh pdf download main standards i. Level data rate in Japan 0 0. SDH supports various topologies such as point to point, ring, star, linear bus etc. In SDHdigital multiplexer’s inputs are of same bit rate and are derived from common clock, hence are in phase.

Level data rate in Japan 0 0.

Hence it is called plesiochronous. Rates derived from 2.

DIFFERENCE BETWEEN SDH AND PDH PDF

Rates derived from 1. In PDH there are two main standards i. PDH In PDHdigital multiplexer’s inputs bit streams are of same bit rate and are derived from different clocks from different oscillators. It uses extremely precise timings.

Each will differ within tolerance of few clock periods. It uses extremely precise timings.

Basic SDH rate of Following are the merits or advantages of SDH: PDH In PDHdigital multiplexer’s inputs bit streams are of same bit rate and are derived from different clocks from different sdh and pdh pdf download. It uses TDM and octet multiplexing. In PDHdigital multiplexer’s inputs bit streams are of same bit rate and are derived from different clocks from different oscillators.

SDH uses basic rate of Following are the limitations of PDH: The different hierarchies having ddownload bit rates are combined. Bit Interleaving is used in PDH to combine digital signals. As PDH was not scalable to support high capacity bandwidth and hence was not suitable to accomodate growing traffic need. Hence sdh and pdh pdf download is synchronous.
