The Multiple Application Platform (MAP) Distributed Feedback (DFB) Laser Cassette is an excellent source for dense wavelength division multiplexing (DWDM) system testing. A combination of DFB lasers may be used to create an ITU grid in which optical frequency represented by a DFB laser corresponds to the transmitter in the optical network. The standard MAP DFB Laser can be selected to comply with the 50 GHz ITU grid in the C- and L-band (1527 to 1610 nm). The lasers typically show a side-mode suppression ratio of 40 dB and can be modulated internally from 0.2 to 400 kHz in square, sinusoidal and triangular waves.
