Title: Explain synchronous optical network (SONET) and dense wavelength division multiplexing (DWDM).
Course: Telecommunications II (10006-II) > Section: Working with Optical Wiring

Explanation should include

- defining the term SONET (synchronous optical network)—a technology standard that defines optical signals and a synchronous frame structure for multiplexed digital traffic
- defining the term DWDM (dense wavelength division multiplexing)—a technique for increasing the bandwidth of optical network communication by putting data from different sources together on an optical fiber, but at different wavelengths
- understanding the factors involved in the use of each.

Process/Skill Questions:

- What OSI layer would best describe where SONET resides?
- What are the implications of using SONET vs. DWDM?
- What format employs multiple light wavelengths to transmit signals over a single optical fiber?
