EDFA Amplifier
A line of Gain Flattening Erbium-Doped Fiber Amplifiers are designed for in-line amplification of DWDM networks. When a standard EDFA is used to amplify multi-channel DWDM signals, the output power level of various channels will vary according to the gain profile of the erbium fiber. This gain variation can be as great as 6 dB in magnitude. The EDFA-GB-R is unique in its dual-stage amplification and internal Gain Flattening Filter (GFF) to compensate the erbium fiber gain variation.

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.
