TAFA3000

DATA SHEET – NOVEMBER 2007 Integrated Transmitter and Fiber Amplifier TAFA3000 0.05 – 18 GHz, 1555 nm Externally Modulated Transmitter with Integrated EDFA The Emcore TAFA3000 is an integrated high-performance externally modulated transmitter and erbium doped fiber amplifier with guaranteed performance over the 0.05 – 18 GHz frequency band. It incorporates a high dynamic range lithium niobate Mach Zehnder optical modulator. It provides 19 dBm of optical output power from the integrated EDFA. The unit can be used to construct transparent optical links for microwave signal distribution, microwave delay lines, point-to-point data links and other applications where it is necessary to transport RF and microwave signals over long distances without signal degradation. The unit operates at a nominal optical wavelength of 1550 nm and ITU wavelengths are available for CWDM and DWDM applications.
