Published time : 2019-04-18The AD5770R is a 6-channel, 14-bit resolution, low noise, programmable current output, digital-to-analog converter (DAC) for photonics control applications. The device incorporates a 1.25 V, on-chip voltage reference, a 2.5 kΩ precision resistor for reference current generation, die temperature, output monitoring functions, fault alarm, and reset functions.
Published time : 2017-09-20EDFA (Erbiur Doped Fiber Amplifer) is a representative one of fiber amplifiers. Since the EDFA has a working wavelength of 1550 nm, which is consistent with the low loss band of the optical fiber and its technology is relatively mature, it is widely used.
