DFB Laser Modules: EM657 Datasheet

G&H offers a range of distributed feedback lasers (DFB) that provide smooth, tunable wavelength control and the narrow spectral width required for precise fiber optics. Applications for these products include spectroscopy and fiber optic communications. The EM657 RF Transmitter integrates a high bandwidth fiber-coupled DFB laser with both an ultra-low noise laser current source and temperature controller. The module also contains an optical isolator and back facet monitor detector readout amplifier.
