EDFA

Nuphoton’s fiber amplifiers are designed for single channel and DWDM fiber optic communication applications. These amplifiers are optimized for flatness and noise performance. Linear Polarized / Polarization Maintaining (PM) and Multimode (MM) amplifiers are available. The hardware and chassis footprint of these amplifiers are optimized for power dissipation sensitive space limited applications.

The C-band EDFA is the smallest DWDM fiber amplifier in the world in half MSA fooptrint. The Low Noise EDFA has the lowest noise figure industry, as low as 3.5dB. The High Power EDFA can deliver up to 5W output in a in compact footprint of 130mm x 86mm x 16 mm. The Pulsed YDFA is optimized for pulsed signal amplification at 1064nm wavelength.

All amplifiers come with dedicated digital and analog circuitry for monitoring and control. The user friendly software interface displays alarms and monitoring data. All key parameters like input and output power, laser diode current and case temperature are monitored and controlled within safe limits. A variety of user interfaces options are available including RS232, Ethernet, I2C and JSON.

The units are also available in rack mount and desktop chassis footprints. The amplifiers are CDRH (IEC 60825-1 & IEC 60825-2) compliant for laser safety and comply with Telcordia GR1312 requirements. Nuphoton’s fiber amplifiers are widely used in Telecom, Oil & Gas Sensing, Free Space Communication (FSO), RF over Fiber (RFoG) and R&D industries.
