                                     Internet spotlight. The valuations of optical companies have been
                                     multiplied by this single act. The craziness slowed a bit at the end of
                                     2000, but it is expected to regain momentum again.An industry that
                                     is only five years old has created a gold rush that pits the three net-
                                     working giants (that is, Cisco, Lucent Technologies, and Nortel Net-
                                     works) against one another.
                                        The long-term goal is to make a pure optical network in which a
                                     light packet shuttles digital data at tremendous speed without ever
                                     having to be converted into electrical signals.A group of optical start-
                                     ups is aiming to deliver the components and new technologies in
                                     order to make end-to-end optical a reality. No one is sure when all-
                                     optical networks will become the norm, but within 10 years, these
                                     networks should be deployed at major companies. Plenty of research
                                     and development dollars and effort will be directed toward pure opti-
                                     cal switches and optical technologies for metropolitan markets.
                                        The pace of this fiber network buildout has been nothing short of
                                     astonishing. Carriers such as Qwest Communications International,
                                     Level 3 Communications, and Global Crossing have snapped up opti-
                                     cal gear (lasers, amplifiers, and other components) so fast that short-
                                     ages have occurred. Manufacturers and start-ups cannot ramp up
                                     production quickly enough to meet the demand. The companies sup-
                                     plying the underlying components, such as Nortel, Lucent, and
                                     Cisco, are also struggling to keep up with the demand. Nortel esti-
                                     mates that it will spend $260 million to boost its production by 30
                                     percent in 2001. One telecom research company expects annual
                                     spending on optical networking equipment to quadruple over three
                                     years, to $23 billion, which can be seen in Figure 9-3.
                                        The economics of optical networking are now starting to appear
                                     and are becoming very favorable. For example, the cost of installing
                                     optical networks over the traditional  time-division multiplexed
                                     (TDM) networks of the past are favorable, representing as much as
                                     a 50 percent savings over traditional TDM installation costs. Figure
                                     9-4 attempts to show this relationship of installed costs for optical
                                     versus  TDM equipment. The savings for long-haul networks can
                                     mount up quickly in this way.
                                        This figure shows that there is a 50 percent or better savings at
                                     the representative number of OC-48s installed. Carriers like the
                                     average savings per point of presence (POP) of $520,000. This allows
