Flex Circuit

Today’s communication technologies demand solutions that are smaller, lighter, and faster than ever before. This is evident in the widespread adoption of fiber optics in high-performance applications. At the core of these solutions are compact, reliable, and adaptable cable assemblies, which provide design engineers with the flexibility to deliver optimized performance without compromising space.

As communication systems evolve, maximizing internal airflow is more critical than ever. Fiber Optic Flex Circuit Assemblies (FOFCA) address the growing need for efficient cable management. These assemblies offer a clean, organized way to route fiber between boards, shelves, or even tight, complex spaces, ensuring both performance and spatial efficiency.

Flexibility is a key part in simplifying a system. Fiber can be configured in nearly any routing layout, whether point-to-point, shuffled, or in predefined patterns—to accommodate the specific needs of a given application.

FOFCA is manufactured based on custom design files, defined parameters, and application-specific requirements, allowing precise and space-efficient fiber routing within the system.

The use of polyimide materials and conformal coating adhesives ensures robust fiber protection, meeting the stringent durability requirements of harsh industrial environments.

The fiber circuit is mainly composed of four parts: adhesive substrate, optical fiber, coating glue and a termination connector. Substrate size & shape, fiber type, channel number, fiber leading-out form, connector type, fiber path, and optical cross relationship are some of the specs that can be customized upon demand.

Flex circuits can be terminated with a wide range of industry-standard connectors including MTP, MXC, LC, and SC. They also can be provided unterminated, allowing optical terminations to be applied as needed. Circuit dimensions range from just a few millimeters in width to large, complex sheets up to 1,240 square inches. Typically, 500mm x 500mm substrate can accommodate over 300 fibers.

A single-layer optical plane can support anywhere from a few to several hundred or even thousands of channels. To further increase capacity, fiber channels can be multiplied through stacking, which is typically achieved using two primary stacking methods.

1. Physical Stacking: For most designs, keeping layer counts under five offers optimal flexibility—but if your system needs more, multi-layer stacks beyond that are possible.
2. Integrated Stacking: When fiber routing is highly complex, integrated stacking is the optimal solution. By treating all layers as a single, cohesive unit, it enables efficient reorganization of fiber paths to handle even the most intricate routing challenges.
