1550 nm Mode Field Adapter

The 1550 nm Mode Field Adapter is a passive fiber-optic device used for optical field adaptation and transmission between different types of optical fibers. This product is designed for an operating wavelength of 1550 nm. It adopts a structure with a 62.5/125 μm multimode fiber input and an SMF-28e single-mode fiber output, making it suitable for mode field adaptation requirements between specific fiber systems. The product features a compact package, relatively low insertion loss, and relatively high return loss. Its maximum continuous optical power is 500 mW. In a no-connector configuration, the maximum insertion loss is 3.0 dB and the minimum return loss is 40 dB. The product supports different connector, fiber jacket, and fiber length configurations and can be used in applications such as fiber-optic communications, optical testing, and laboratory fiber-optic system integration.
