Description
The 3970-type, externally modulated 1550 nm transmitter provides CATV systems integrators one of the fastest and easiest paths to customer value-added, high-performance solutions.
The 1550 nm transmitter engine incorporates a source laser optimized to improve transmitter and link performance with high specifications and better signal quality. This advantage drives superior control of RIN through fiber and management of dispersion, stimulated brillouin scattering, and self-phase modulation for better noise and distortion performance over long-distance applications.
