8. Detailed Product Description

The GracyFiber 90° Optical Path Turning Fiber Array is developed for optical systems where conventional straight fiber routing cannot meet packaging space requirements. By introducing a controlled fiber bending structure, the assembly allows the optical path to turn 90° while maintaining stable coupling performance.

In high-density optical modules and photonic integration systems, optical packaging space is becoming increasingly limited. Traditional fiber array structures may require additional routing space, creating challenges for compact system integration. The 90° optical path turning design addresses this challenge by redirecting the fiber path within a smaller mechanical footprint.

The product supports configurable channel counts from 1 to 24 channels, enabling adaptation to different optical interface requirements. Multiple core pitch options, including 250 µm, 300 µm, and 500 µm, allow designers to select the appropriate fiber arrangement according to the optical device structure.

For optical interface compatibility, the MT side supports 0° and 8° polishing angles, while the FA side supports 4°, 6°, 8°, and 12° polishing angles. These options provide flexibility when matching different optical coupling architectures.

The assembly uses stainless steel metal components and an integrated polishing process to improve structural reliability and control angular accuracy.

The 90° Optical Path Turning Fiber Array is suitable for compact optical modules, silicon photonics coupling systems, optoelectronic integrated devices, and high-speed optical interconnect applications where space-efficient fiber routing is required.


9. Application Scenario

Application 1 — High-Density Optical Modules

In high-density optical modules, internal optical routing space is limited and multiple fiber channels must be positioned within a compact package.

The 90° Optical Path Turning Fiber Array allows the fiber path direction to be changed within the module structure, helping reduce routing constraints while maintaining multi-channel optical coupling capability.


Application 2 — Silicon Photonics Chip Coupling

Silicon photonics packages require precise optical interfaces between fibers and photonic chips.

The 90° turning structure enables flexible fiber routing around the photonic package while supporting customized channel count, pitch and polishing-angle configurations.


Application 3 — Data Center Optical Interconnect

High-speed data center optical systems require compact and reliable optical packaging solutions.

The product provides a space-efficient fiber coupling approach for optical modules and interconnect assemblies where internal routing density is a key design consideration.
