2 Introduction to EM316EDFA Optical Amplifiers
The fiber optic amplifier module is used to increase an optical signal for extended range or clarity without electrical conversion circuitry. The MRV EM316EDFA modules boost an optical input up to 20 decibels. The amplifier also has a bandwidth of 40 nm, making it suitable for use in wavelength division multiplexing (WDM) applications as an optical spectral amplifier. The module may be controlled from the network through the MRV
Optical amplifiers operate in different modes, depending upon their position in the optical link. The EM316EDFA is available in two configurations to fill the necessary roles in your network.
