What is the purpose of the validate step in the EPT design process?

• A.This step is used to measure optical power performances over an existing network before making changes.
• B.This step is optional and is useful to verify the network element layout before going through the commission step.
• C.During this step, the configuration available on the involved network elements is compared with the design provided by EPT.
• D.During this step, the run design action is triggered for network design consistency check and errors fixing.

What is a Shared Risk Group (SRG)?

• A.A set of nodes that share a common risk of hardware failure
• B.A set of boards that share the same failure risk
• C.A set of fibers that share the same latency risk
• D.A set of network resources that share a common failure risk

Where is the OPS card equipped to provide the optical channel protection?

• A.Before the transponder, on the client side, towards the external device
• B.Between the transponder and the amplifiers
• C.Between the transponder and the filter
• D.Between the filters and the amplifiers

What is an optical switch?

• A.A device that converts optical signal to electrical to allow switching through the electrical matrix, and then again to optical towards the next card (and versa).
• B.A device that selectively transfers an optical signal from one port to another.
• C.A device that selectively transfers an optical ODU frame from one port to another.
• D.A device that groups multiple lambdas in one multiplexed signal.

What is the block that converts the colorless (or black and white) client signal to a specific optical channel in a WDM system?
