Erbium Doped Fiber Amplifier
EDFA
-
EDFAs are based on the light amplification in erbium-doped fiber, which are optically pumped by means of 980 nm or 1480 nm light sources. In this way, the light of a larger wavelength within the C or L band applied to the input of the amplifier is amplified, thus widening the range of optical communication links. EDFAs typically operate in saturation and the average signal power determines the average gain. The dynamics of EDFA are unaffected by the sequence and dynamics of a digital signal or channel interaction in DWDM systems. As a result, multiple channels can be bundled within the total erbium spectral amplification bandwidth. However, the total average output power in both cases is determined by the saturation power of the specific EDFA.

Multiplexers (MUX)
WDM
-
It is highly desirable to reduce the number of cables required to communicate between spaces on Navy ships due to increased weight, cost and maintenance concerns. To reduce weight and expense, copper-based NTDS parallel and serial type cables can be converted to fiber optic and multiplexed using Wavelength Division Multiplexing (WDM) technology. WDM technology allows for multiple fiber optic wavelengths to be combined in a single fiber and then separated back to individual fibers at the distant end. Using Coarse WDM (CWDM) which utilizes wavelengths 20nm apart ranging from 1271 nm to 1611 nm, provides for up to 18 optical wavelengths to be combined into a single fiber. Optionally Dense WDM (DWDM) can be used allowing for up to 160 optical wavelengths.

Standard Optical Interleaver
-
An innovative technique for expanding the number of channels per fiber involves an optical device, called an optical interleaver. For example, in most DWDM equipment, the standard channel spacing is 100 GHz. But spacing the signal-carrying frequencies every 50 or even 25 GHz can double or even quadruple the number of channels per fiber. This job is accomplished by an optical interleaver. Such a device takes two multiplexed signals with 100-GHz spacing and interleaves them, creating a DWDM signal with channels spaced 50 GHz apart. The process can be repeated, creating even denser composite signals with 25-GHz or 12.5-GHz spacing. The signals at the receiving end are recovered with the same devices used as splitters or optical de-interleavers. Thus, devices and/or networks can be upgraded without requiring that all devices be upgraded, or network bandwidth can be increased.
