the erbium-doped fiber, allowing more electrons to reach high energy level. As these electrons relax into lower energy levels within the fiber band structure, they emit photons in the 1550 nm range that add to the optical signal at the fiber input, causing the necessary optical gain. A coupler (usually called a WDM component) is used to combine the optical signal carrying the information with the pump signal. At the other end of the erbiumdoped fiber, the optical signal is output with a gain of 30 40 dB. The length of the fiber is chosen to provide the necessary gain and to decouple the pump signal from the optical signal. Several versions of EDFAs exist. Some are pumped from both ends of the fiber to achieve higher optical gain; some are pumped using 980 nm (instead of 1480 nm) for higher reliability and lower cost. Construction of the amplifier, however, is basically the same, with fiber-in/fiber-out that allows extremely easy coupling to the fiber network. Additionally, erbium-doped fluoride fiber amplifiers are very promising for applications requiring flat gain over a wide wavelength window. These amplifiers are still under investigation, but they promise to provide flat gain (within several tenths of a dB) over a range greater than 15 nm (2 THz). Other kinds of fiber amplifiers are under investigation. Praseodymium-doped fiber amplifiers (PDFAs) provide optical gains in the 1300 nm wavelength domain, but they are not as efficient as EDFAs in the 1550 nm region. 22.5 Optical Fibers An optical fiber is a cylindrical dielectric waveguide made of low-tech materials such as silica glass. Its central core, through which the light is guided, is embedded in an outer cladding of slightly lower refractive index. As a result of recent technological advances in fabrication, light can be guided through 1 km of glass fiber with loss as low as about 0.16 dB. When the core diameter is small (less than 10 microns), only a single mode is permitted and the fiber is said to be single-mode fiber. Fibers with large core diameters (50 and 62 microns are standard diameters) are multimode fibers.

where fp is a valid file pointer. It returns true if an error has occurred during the last file operation; it returns false otherwise. Because each file operation sets the error condition, ferror( ) should be called immediately after each file operation; otherwise, an error may be lost. The rewind( ) function resets the file position locator to the beginning of the file specified as its argument. The prototype is void rewind(FILE *fp) where fp is a valid file pointer.

Here, member can be either a method or an instance variable. This form of base is most applicable to situations in which member names of a derived class hide members by the same name in the base class. Consider this version of the class hierarchy from the preceding example:

ciscoasa(config)# policy-map type inspect mgcp L7_policy_map_name ciscoasa(config-pmap)# description string ciscoasa(config-pmap)# parameters ciscoasa(config-pmap-p)# call-agent IP_address group_ID ciscoasa(config-pmap-p)# gateway IP_address group_ID ciscoasa(config-pmap-p)# command-queue #_of_commands

To set the Privilege EXEC password, use the enable password command:
