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.

Features
■ Extremely fast time to market and very low engineering investment
■ Superior CNR, CSO, and CTB performance on two
   high-power optical outputs
■ Mobile field-tuning application provides real-time
   performance optimization
■ High SBS suppression capabilities enhance architectural options and coverage
■ Multiple programmable tuning optimizations per
   transmitter facilitate inventory management and
   performance across architectures

Applications
■ High-performance supertrunking links
■ High-launch power distribution networks
