Flexible Structured Optical Modules

摘要

Optical modules as used in various types of communication systems are formed to include a flexible substrate to support various optical, electronic, and opto-electronic module components in a manner that can accommodate various packaging constraints. The flexible substrate is formed of a polyimide film is known to exhibit excellent electrical isolation properties, even though the films are generally relatively thin (on the order of 10-100 μms, in most cases). The flexible polyimide film is sized to accommodate the constraints of a given package “footprint”; more particularly, sized to fit an open ‘floor area’ within package, allowing for a populated film to be placed around various other “fixed-in-place” elements . The polyimide film is easily cut and trimmed to exhibit whatever topology is convenient, while providing enough surface area to support the affixed components and associated optical fiber traces.
