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 81um in 12, 16 and 20 fibers.

Angular tolerance of PM alignment is ≤ 3° in both slow and fast axis alignments, assuring ≥ 20 dB ER.
