A Carrier Hotel has all of the following attributes.

The ITU has defined four core segments. They are referred to as ________, ________, ________, ________.

A cross connect matrix within a SONET mux ________ channels together onto one circuit.

A DWDM network is designed with optical amplifiers placed strategically between point A and point B. The number and placement of the Op Amp is determined by:

The regional communications interconnection point between metro and core networks and between core network and core network is referred to as the ________.

Core networking equipment is typically placed in a Carrier Hotel located within a centralized area within a region.

The ITU has designed specific frequencies for optical DWDM systems. The windows defined by the ITU are ________, ________, ________ and ________.

The NDZSF stands for:

The primary advantage a mesh network has over a ring configured network is the low switch over times from working to protection path.

It is not necessary to run dispersion tests and characterize fiber used in core networks.

Fiber optic cable laid across the ocean floor is referred to as submarine cable.

A SONET mux is defined by its line speed. The most common line speeds deployed in the core network are:

Multiplexers are used in the core network to aggregate DS0's onto the core network.

One fiber optic strand is capable of carrying billions of bits every second allowing for multiple wavelengths each carrying OC-192 speeds on one strand of fiber.

ESMF is a type of fiber deployed in the core network.

The term Op Amp refers to an optical amplifier used to repeat or regenerate the signal.
