Because SONET/SDH uses "synchronous TDM multiplexer" to multiplexe signals from multiple electrical sources . All clocks in the system are locked to a master clock.
SONET uses an inverse multiplexing technique called virtual concatenation. SONET, which is the standard used in the United States and most of Europe, stands for Synchronous Optical Network.
SONET (Synchronous Optical Network) is a physical layer network technology designed to carry large volumes of traffic over relatively long distances on fiber optic cabling.
Fiber optic cables
Subscribers: the devices that attach to the network, such as telephones and modems. Subscriber line: the link between the subscriber and the network. Exchanges: the switching centers in the network. Trunks: the branches between exchanges. Trunks carry multiple voice-frequency circuits using either FDM or synchronous TDM. By: khurram, sibbi Pakistan

SONET
It is an acronym for 'Synchronous Optical Network'. I can find no other meaning for it. There is a word sonnet which is a type of poem.
Synchronous optical network (SONET)
OC-n / OC-xxx indicates Optical Carrier signals which are carried over a SONET (Synchronous Optical Network) fiber optical network. The numbers after OC indicate various levels or data rates in the SONET hierarchy. Hierarchy goes like OC-1, OC3, OC-12, OC-24, OC-48, OC-96, OC-192 and OC-768 OC-1 is a SONET line with transmission speeds of 51.84 Mbit/s. OC-192 has a speed of 9953.28 Mbit/s (almost 10Gbps, so also called SONET 10G). You can get more details in SONET literature. - Neeraj Sharma

Synchronous Optical Networks (SONET) have various optical networks. An OC-3 circuit is one of these. The answer is yes, since OC-3 is a product of the SONET architecture.
it is a digital network unit for sonet.
A SONET is a type of network technology layer that is physical. It is used for transporting a lot of traffic over fiber optic cabling.
SONET (Synchronous Optical Networking) is used for high-speed telecommunications networks to provide reliable and efficient data transmission over fiber optic cables. It offers synchronous data transmission, enabling multiple data streams to be multiplexed and transmitted over a single optical fiber. SONET is commonly used in backbone networks to support high-bandwidth applications such as video streaming, internet connectivity, and phone services.
