GracyFiber SM/MM Fiber Arrays provide precisely arranged optical fibers in compact multi-channel assemblies for coupling light between fibers and planar or discrete optical devices. The available configurations range from a single channel to 128 channels, allowing the same product family to address both low-channel-count optical assemblies and dense photonic interfaces.
The fiber geometry is defined primarily by channel count, core pitch, and pitch tolerance. A 250 µm pitch is available for the 2-channel configuration, while 127 µm or 250 µm pitches are specified for 4-, 8-, and 12-channel versions. From 16 channels upward, the documented pitch is 127 µm. Pitch tolerance varies with array size, ranging from ±0.3 µm for lower-channel-count versions to ±1.0 µm for 96- and 128-channel configurations.
The array can be produced using Pyrex, Tempax, Quartz, or Silicon, with lidded or lidless construction. Multiple polishing geometries are documented, including 8°, 41°, 82°, and 90°, as well as customized angles. This allows the fiber end-face geometry to be selected according to the corresponding optical interface.
Optical specifications include insertion loss of ≤0.5 dB, with 0.3 dB listed as typical, and return loss of ≥45 dB for UPC and ≥55 dB for APC.
The product family supports multiple fiber and connector configurations, making it suitable for integration into PLC/AWG devices, silicon photonics packages, wavelength-selective switches, optical switches, coherent modules, sensing systems, and laboratory photonics setups.
In silicon photonics assemblies, a fiber array can provide a defined multi-fiber interface between external optical fibers and the photonic device.
The available 127 µm pitch, multiple polishing angles, compact array dimensions, and configurations up to 128 channels allow the array geometry to be selected according to the photonic interface and channel density.
PLC splitters and AWG-based optical devices require organized fiber interfaces for coupling optical signals into and out of planar optical circuits.
The GracyFiber fiber array family provides multiple channel-count and pitch options, together with lidded or lidless construction and different connector configurations, for integration with these planar optical assemblies.
WSS and optical switch systems may require multi-channel fiber interfaces with controlled pitch and physical alignment.
The documented array configurations provide up to 128 channels, with channel-dependent pitch tolerances and multiple fiber-protection options for integration into optical switching assemblies.

For this SM/MM Fiber Array family, the supplied documentation provides standard and customized configurations covering channel count, wavelength, pitch, array material, polishing angle, fiber protection, fiber length and connector type.
The document also states that the arrays are manufactured and fully tested in an ISO-class cleanroom environment. It does not specify the cleanroom class or claim a separate company ISO certification.

Standard configurations listed in the product specification include 1, 2, 4, 8, 12, 16, 24, 32, 48, 64, 96, and 128 channels.
The documented configurations use 127 µm and/or 250 µm core pitch, depending on channel count. For example, the 2-channel configuration uses 250 µm, while 16-channel and higher standard configurations use 127 µm.
The supplied specification lists an insertion loss of ≤0.5 dB, with 0.3 dB typical.
The standard document lists 8°, 41°, 82°, and 90°, with customized angles such as 12° and 21° also available. The specified angular tolerance is ±0.5°.
Yes. The supplied specification explicitly lists customized fiber types and fiber lengths. Connector options include FC, LC, SC, E2000, MT, MPO and MMC.
