Neptec’s Fiber Array Unit (FAU) is designed for superior stability and low insertion loss, enabling reliable performance in chip integration-based applications. Available to customize in order to meet specific integration needs in PM, SM, and hybrid (PM+SM) configurations.

For high density integrations we build configurations with reduced pitch FAUs down to 127/250µm v-groove pitches. in 12, 16, 36 and 72 fibers.

PM alignment accuracy exceeds industry standards, with an angular tolerance of ≤ 1.5° (industry standard ≤ 3°) in both slow and fast axis alignments, assuring ≥ 20 dB extinction ratio (industry standard ≥ 18 dB).
