Mini 0.6~6GHz Analog Wideband Transceiver Module Optical Transmission Link Fiber Optic Transmitter
The Mini analog wideband transceiver module(Fiber Optic Transmitter) 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 0.6GHz to 6GHz. 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.
