DESCRIPTIONEAM Laser Transmitter-2

The EML (Electro-absorption Modulated  Laser) transmitter evalsuation board consists of a conventional Distributed Feed-Back (DFB) laser and EA modulator. The modulation signal is applied to the modulator section while the laser section operates CW allowing extremely low wavelength chirping. The module includes an optical isolator, monitor photodiode, thermistor and a thermo-electric cooler.
