EDFA, dual pump, optional 4/8/16 ports with output power +16dBm and +19dBm and dual power supply
PPC’s Erbium Doped Fiber Amplifier (EDFA) is an optical amplifier that is used to boost optical signals carried through a fiber optic communication system. The power of a data transmitter may be boosted with a high-power EDFA before entering a long fiber span, or a device with large losses, such as a fiber optic splitter. It operates at 1550 wavelength, which is in line with the low-loss band of fiber, where telecom fibers have their loss minimum. The core element of a fiber amplifier is a piece of fiber doped with a rare earth element, which can provide laser amplification via stimulated emission when it is optically pumped with other light injected into the fiber. PPC offers a reliable optical power output stabilizing circuit and laser optical cooling to control the temperature in the circuit. This guarantees optimum performance and long life. The microprocessor has laser condition monitoring, digital display, fault warning, network management and various other functions.
