In Synchronous Optical Networks (SONET), how much faster is the data rate of an electrical level STS-192 compared to an STS-1?

In Synchronous Optical Networks (SONET), the structure and hierarchy of data rates are clearly defined. An STS-1 (Synchronous Transport Signal level 1) has a data rate of 51.84 Mbps. In the SONET hierarchy, STS-192 is the signal level that corresponds to a data rate of 9.95328 Gbps (or 9,953.28 Mbps).

To determine how many times faster STS-192 is compared to STS-1, you can perform a simple calculation:

1. Convert both data rates to the same unit (in this case, Mbps).

• STS-1 = 51.84 Mbps

• STS-192 = 9,953.28 Mbps

2. Divide the data rate of STS-192 by the data rate of STS-1:

• 9,953.28 / 51.84 = 192

This calculation shows that the STS-192 level is indeed 192 times faster than STS-1. Therefore, selecting the first option demonstrates a solid understanding of the hierarchical structure of SONET and the multiplying rates of the different signal levels. Understanding these data rates is crucial for optimizing bandwidth and
