Optical Networking and SONET Standards

The video tutorial discusses the evolution of high-speed networks, focusing on synchronous optical networking (SONET) and synchronous digital hierarchy (SDH). It explains how these standards allow multiple digital signals to be transmitted over a single fiber using the same clock, eliminating the need for separate connections. The tutorial also covers the differences in throughput and bandwidth calculations between SONET and SDH, detailing various speeds and their equivalents.

What type of connections are typically used in modern data centers for high-speed networking?

• Copper cables

• Wireless connections

• Optical connections

• Satellite links

Why is it called a synchronous optical network?

• Because it synchronizes with the internet

• Because it uses the same clock for all signals

• Because it uses different clocks for different signals

• Because it uses asynchronous signals

Which standard is primarily used in the United States and Canada?

• SONET

• ITU

• SDH

• ANSI

What does SDH stand for?

• Synchronous Digital Handling

• Synchronous Data Handling

• Synchronous Digital Hierarchy

• Synchronous Data Hierarchy

What is the equivalent of an STS-1 speed in SDH?

• STM-4

• STM-16

• STM-1

• STM-0

What is the bandwidth of an OC-3 connection?

• 51.48 Mbps

• 155.52 Mbps

• 622.08 Mbps

• 9.953 Gbps

Which of the following is the correct bandwidth for an OC-12 connection?

• 9.953 Gbps

• 155.52 Mbps

What is the speed of an OC-192 connection?

• 155.52 Mbps

• 51.48 Mbps

• 622.08 Mbps

• 9.953 Gbps

Which of the following is NOT a correct pairing of SONET and SDH speeds?

• OC-12 and STM-4

• OC-48 and STM-8

• OC-3 and STM-1

• OC-1 and STM-0

What is the main challenge when dealing with SONET and SDH standards?

• Ensuring data security

• Understanding the different clock speeds

• Setting up the physical connections

• Memorizing the different bandwidths and their equivalents
