each node the upstream RF channels modulate an optical transmitter of a different wavelength from the downstream wavelength and are coupled to the optical ber by an optical coupler. A simpli ed diagram of this technique is shown in Figure 8-11. Because the choices for many variations of this technology are many, the most common are illustrated. In most cable television system applications the headend signal source contains the downstream system optical transmitters and the upstream optical receivers/demultiplexers. The nodes optical receivers convert the downstream signals to RF and provide optical transmitters on the upstream path. In between there is no device of any kind unless it is an optical power divider. This type of system is sometimes termed a passive optical network (PON). The variations in optical-system design used by cable systems employ several methods. At the primary headend, if the rst optical cable length is long, the choice would be to use several RF-to-optical transmitters operated at different wavelengths driven by 18 to 20 RF channels. This approach allows a higher drive signal level to the laser transmitter, resulting in a larger received signal at the end of the run. Another approach would be to use a high-output transmitter and carry a greater number of channels. A change in the network topology in many existing systems is often out of the question due to increased costs and downtime. Most systems have been in existence many years and have undergone several rebuilds where optical ber has been added as the main signal transportation method. Manufacturers of optical cable and electro-optical transmitters/receivers often have a customer applications department offering cable operators with design assistance. Such services are often without cost. Most manufacturers of cable system optical equipment carry a good

Zero No profile is loaded or unloaded. When using this option, remember, some applications might require the presence of a user profile to function properly, for example, Program Neighborhood Agent and Web Interface. This setting provides the fastest user-switching time, but at the expense of not supporting some applications requiring access to the Hot Desktop User s user profile. One A local profile is loaded and unloaded (This is the default value if the previous registry value is not present). When using this option, the local user profile is created, but Roaming or Mandatory profiles are not loaded. This setting provides compatibility for the widest range of applications (flexibility), while minimizing the profile load time (speed). Two No restrictions on which profile is loaded or unloaded. The standard Windows algorithm is used to locate and load the user s profile. This setting is slower when switching users, but it provides compatibility with all applications using profiles.

A function macro creates your own custom function. It returns a value. All function macros begin with the Function keyword. They end with the End Function. They can be called from worksheet cells. This makes them work like any of the functions Excel already has (such as IF, SUM, etc.).
