The GracyFiber 2D Fiber Array is a high-density optical interface designed for advanced photonic packaging where a conventional linear fiber array cannot provide sufficient optical I/O density. Using a two-dimensional matrix fiber architecture, the array enables large numbers of optical channels to be arranged within a compact footprint for photonic engines, silicon photonics packaging, co-packaged optics, and high-bandwidth computing systems.
The available configuration covers 16 to 1024 channels, with a 127 μm core pitch and ±1 μm core-pitch tolerance. The product supports a 1260–1650 nm wavelength range and multiple fiber and connector configurations. The supplied documentation identifies applications including 800G / 1.6T transceivers, AI / GPU optical interconnects, CPO, optical engines, and HPC systems.
The source documentation also identifies low optical crosstalk, channel-to-channel uniformity, SM/MM/PM fiber compatibility, and compact photonic-engine packaging as key product characteristics.
These applications are explicitly listed in the supplied product documentation.

Exact single-mode fiber designations require confirmation before publication.
The specification table states:
The product description separately states glass or silicon substrate, so this point requires confirmation.
The GracyFiber 2D Fiber Array is designed to increase optical I/O density by arranging fibers in a two-dimensional matrix rather than a conventional one-dimensional linear row. This architecture is relevant to photonic systems where many optical channels must interface with a chip, optical engine, or photonic package within a restricted physical footprint.
The supplied configuration uses a 127 μm fiber pitch with ±1 μm pitch tolerance and supports channel counts ranging from 16 to 1024. This makes the architecture particularly relevant where scaling the number of fiber interfaces becomes a packaging constraint.
Optically, the product is specified for a wavelength range of 1260–1650 nm, with insertion loss of ≤0.8 dB and a typical value of 0.5 dB. Return loss is specified at ≥40 dB for UPC interfaces and ≥50 dB for APC interfaces.
The product documentation also highlights low optical crosstalk and channel-to-channel uniformity, which are important characteristics when a large number of optical paths are placed in close proximity.
Multiple connector interfaces and fiber constructions are available according to the supplied table. This allows the 2D Fiber Array to serve as a dense optical interface between external fiber routing and photonic-engine or chip-level optical interfaces.
Compared with a linear fiber-array architecture, the 2D matrix structure is intended specifically for applications requiring substantially greater channel density within a compact optical package.
In CPO architectures, optical interfaces are placed close to switching or processing devices, creating a need for high optical I/O density within limited package space.
The 2D matrix arrangement allows multiple fibers to be organized across two dimensions, making the product suitable for dense photonic-engine interfaces used in CPO packaging. CPO is explicitly identified as an application in the supplied product documentation.
AI and GPU computing platforms require increasingly dense optical connectivity between processing and networking resources.
For photonic engines used in these architectures, a 2D Fiber Array can provide a compact interface for a large number of optical channels. The supplied product information specifically identifies AI / GPU Optical Interconnects and High-Performance Computing as target applications.
The 2D Fiber Array can be used as a multi-channel optical interface in transceiver or optical-engine packaging where high fiber density and precise channel positioning are required.
The supplied documentation explicitly lists 800G / 1.6T transceivers as an application.
