Single-mode Fiber Arrays are widely used in communications, optical sensors, medical devices and scientific instruments to efficiently transmit signals across and between connected optical devices. Our single-mode Fiber Array is a product designed for high-precision applications. It covers a wavelength range from 320nm to 2200nm and is suitable for a variety of optical applications. Moreover, this single-mode fiber array is highly accurate, with a linear array fiber alignment accuracy of ±0.3um, which is especially suitable for small-mode field fiber arrays. The use of our single-mode fiber arrays can greatly reduce the losses in optical waveguide devices and optical coupling alignment, enabling more accurate optical measurement and transmission.
