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 EM316LNXNM-OT Network Manager Module.
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.
EM316EDFA-BR C-band optical amplifier booster
C-band in-line optical amplifier
EM316EDFA-LPR
C-band pre-amplifier
The example below illustrates how the EM316EDFA optical amplifiers fit into an optical link.

EM316EDFA-BR is used as long haul booster module in combination with an EM316EDFA-LPR inline
pre-amplifier.
