| Datasheet Optical Amplifiers Features Three models - EM316EDFA-BR (booster amplifier) - EM316EDFA-SBR (single wavelength booster) - EM316EDFA-LPR (in-line and pre-amplifier) Applications - Metro DWDM distance extension - Single wavelength distance extension Automatic Gain Control (AGC) Managed and non-managed operation Overview Fiber Driver(R) EM316EDFA modules provide a multi-function, lownoise, Erbium-Doped Fiber Amplifier (EDFA) solution ideal for metro Dense Wavelength Division Multiplexing (DWDM) as well as single wavelength distance extension applications. The EM316EDFA-BR, EM316EDFA-SBR, and EM316EDFA-LPR are part of the Fiber Driver optical multi-service platform solution family. The EM316EDFA-BR and EM316EDFA-SBR are optical boosters that extend transmission range. The EM316EDFA-LPR may be either an in-line repeater or a pre-amplifier that can strengthen weak signals, optionally extending the link range as well. By performing two functions, the EM316EDFA-LPR also reduces some inventory requirements. The EM316EDFA modules employ a state-of-the-art optical design and sophisticated control circuitry. This technology provides constant gain even when wavelengths are added or dropped in the network. Any fluctuations caused by wavelength filtering are handled by ultra-fast transient suppression.

Telnet and secure shell (ssh) provide convenient access for remote command line management while MegaVision Pro(R), a network management system (NMS) from MRV, provides a graphical user interface (GUI) to control the modules using SNMP. Either way, costly service calls are greatly reduced. EM316EDFA advanced performance monitoring capabilities include real time reporting of input and output power levels, temperature, and signal gain. Optical amplifiers operate in three basic modes, depending upon their position in a data link: booster, in-line, and pre- amplifier. At the transmission end of the link, a booster amplifies the initial signal to extend the signal range. In the middle or at the receiving end of an optical link, the sensitive receiver of an in-line or pre-amplifier repeats the signal for extended range or clarity at the end of the link. In WDM systems, input levels are sums of all the individual input levels from each input wavelength to the amplifier. Contact MRV support for more specific information. EM316EDFA optical amplifiers use automatic gain control (AGC). The module maintains constant gain for each channel according to the gain parameter setting as long as the total output power does not exceed the maximum rated value (see Saturated Output values). The module is initialized with factory values configured for multi-channel applications. As a state-of-the-art multi-channel DWDM optical amplifier, the EM316EDFA-BR and EM316EDFALPR are equipped with gain flattening filters (GFF) providing a flat gain response across the entire C-band and input power range. This feature is not required in the EM316EDFA-SBR module. The EM316EDFA optical amplifiers provide automatic power shutdown when input falls below the threshold. Power shutdown may also be forced through the module management. Fiber Driver EM316EDFA modules are compact, twoslot wide modules. The two-slot chassis supports the EM316EDFA modules in unmanaged applications, and the sixteen-slot chassis supports unmanaged mode or managed optical amplifier applications with the EM316LNXNM-OT module. Other chassis do not support the two-slot EM316EDFA modules.
