Main Features
Core of Co-Packaged Optics
Purpose-built for Detachable Fiber-to-Chip (D-FAU) applications. This array unit bridges the critical gap in CPO systems, enabling seamless optical coupling directly to silicon photonics with unmatched stability.
Micron-Level Accuracy
Manufactured with rigorous polishing standards ensuring exceptional end-face geometry and cleanliness. With core pitch tolerances strictly controlled under 30µm and max fiber end position deviation as low as <15µm, it guarantees deterministic coupling efficiency.
Ultra-Low Insertion Loss
Engineered for strict power budgets. The bare fiber array delivers an ultra-low insertion loss of ≤0.08 dB. When paired with our Low Loss MT termination, the total connectorized insertion loss is kept under ≤0.35 dB, maximizing signal integrity for high-speed transmission.
Tailored to Your Edge
Fully adaptable to specialized silicon layouts. Available in 12, 16, or 32 channel counts, supporting 125µm or 80µm cladding diameters, multiple pitch variations, and both standard Single-Mode (SM) and Polarization-Maintaining (PM) fibers.
Versatile MT Terminations for Every Power Budget

Deployment Scenarios
Next-Gen Pluggable Modules
As transceiver speeds scale to 800G, 1.6T and beyond, the internal optical coupling demands extreme precision. This fiber ribbon array ensures reliable, low-loss routing from the optical engine to the external MPO/MT interface, meeting the strict requirements of cutting-edge single-mode transceiver modules.
Silicon Photonics Integration
Designed specifically for 1D optical edge interfaces in Co-Packaged Optics (CPO) environments. By providing a clean, highly accurate array that perfectly aligns with photonic integrated circuits (PICs), it solves the physical layer connectivity challenge in highly dense computing clusters and switch ASICs.
