Fiber optic has been widely recognized as excellent transmission medium in the areas of telecommunication, local area network, process control, CATV, and video transmission. Along with the development of new technology, there is a growing need for highly reliable fiber optic attenuators. FOCI's fiber optic attenuators is the first and only one to adopt Fused Biconical Taper (FBT) technology. With this innovative patented design, FOCI's A-IF series fixed in-line type attenuator is the most sophisticated device suitable for all applications demanding high performance. The A-IF series come with your choice of different connector terminations, including FC, SC, ST, or other type of connectors specified. With the patented mode filter design, the A-IF series can enhance mode stability dramatically and be readily panel mounted without any dummy fiber.
