1. Photonic networks are based upon a combination of ________ and ________ components and transmission media that allow the delivery of multiple channels of data over any given fiber in the core or backbone network.

2. Channel multiplexing is received by either a means of _______ or _______.

3. The simple power measurements used to find fault conditions in single wavelength systems may be used for measuring parameters of multiple wavelength systems.

4. What are the 2 key structures that comprise a typical photonic network?

5. In the past, DWDM elements were not used in the network—SDH/SONET electro-optical ADMs were used to move tributaries off of or onto the core.

6. Which of the following is not a description of the two general categories of photonic systems that are available?

7. _________ systems are characterized by their ability to accept and transport a variety of incoming signals with a range of formats and characteristics.

8. _________ systems are characterized as the more suitable for the longer term.

9. Two general types of testing are required to manage the complexity of photonic networks: performance assessment and conformance testing.

10. Acceptable test results for optical broadband interfaces differ depending on which optical interface classification the component or network element is designed for.
