Linear multi-output optical transmitter system

摘要

A high fidelity, multi-output optical transmission system is configured utilizing a high power continuous wave YAG laser, multiport splitters, and linearized external modulation. An electro-optical modulator design in combination with a c.w. laser, power splits and couplers attains a multi-octave bandwidth transmitter possessing second and third order distortion characteristics of -60 db and a dynamic range >-140 db/Hz. The system includes multiple individually modulated transmitter outputs which effectively provides bandwidth multiplication with full redundancy for increased transmission reliability.
