Electro-optic modulator Mini 50~3000MHz Analog Wideband Transceiver Module Optical Transmission modulator
The Mini analog wideband transceiver module is a low-cost, high-performance analog wideband transceiver with a very wide dynamic range, designed specifically for optical fiber RF applications. A pair of transceivers will create two-way RF to optical and optical to RF conversion and transmission links that can provide high spurious free dynamic range (SFDR), operating at frequencies from 50MHz to 3000MHz. The standard optical connector is FC/APC for low back reflection applications, and the RF interface is via a 50 ohm SMA connector. The receiver uses high performance InGaAs photodiode, the transmitter uses linear optical isolation FP/DFB laser, and the optical fiber uses 9/125 μm single-mode fiber with working wavelength of 1.3 or 1.5μm.

Rof Electro-optic modulator EDFA Optical Amplifier Erbium Doped Fiber Amplifier YDFA Amplifier
An optical amplifier is a device which receives some input signal light and generates an output signal with higher optical power. Typically, inputs and outputs are laser beams (very rarely other types of light beams), either propagating as Gaussian beams in free space or in a fiber. The amplification occurs in a so-called gain medium, which has to be “pumped” (i.e., provided with energy) from an external source. Most optical amplifiers are either optically or electrically pumped.
Different kinds of amplifiers differ very much e.g. in terms of saturation properties. For example, rare-earth-doped laser gain media can store substantial amounts of energy, whereas optical parametric amplifiers provide amplification only as long as the pump beam is present. As another example, semiconductor optical amplifiers store much less energy than fiber amplifiers, and this has important implications for optical fiber communications. -
