Erbium Doped Fiber Amplifier
S-102
-
The EDFA slot module of FOTS system with built-in power booster EDFA module offers a special function that is able to change the optical signal amplification feature variously, which is followed by user’s driving embedded pump LD freely. The output power of eash pump LD can be controlled separately by the program that is set up by user. When an optimum optical signal amplification particularity is needed, it is made up so that it can be materialized by choosing the Default mode provided along with User mode. More stable application of EDFA is possible through the monitoring of the factors such as in/out signal power, gain, alarm status and pump LD enabled by the application of FPGA processor which makes high speed driving possible. It is also set up that user’s present-time monitoring and control through LCD monitor of system main frame or GUI display for remote control can be possible. Through optimization of amplifier gain, noise figure, and saturated output power, this EDFA module will expand test capabilities in systems, components or sub-assembly manufacturing.

Analog Power Supply
Type NPS-2412
-
National RF's Type NPS-2412 analog power supply was designed to be used in communication equipment where radiated switching inverter noise from conventional “switching type” supplies is not acceptable. The power supply consists of a standard rectified transformer output driving a pair of voltage regulators and filtering networks. The 2412 offers an adjustable voltage output between 2 and 24 volts as well as a fixed voltage output of 12 volts. A maximum of 20 Watts of DC power can be supplied from the unit. As the voltage regulators dissipate power in the regulation process, the power to the load is derated accordingly, dependent on the set voltage to the load. The adjustable regulator is a standard LM-317T integrated circuit device. The fixed regulator is a standard LM 7812 device. Upon customer request, the LM 7812 device may be changed to any voltage rating within the the LM-78xx series of regulators. Contact National RF for this modification if desired.
