Adaptor Type Attenuators
Fiber optic has been widely recognized as an 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-AF series fixed adaptor type attenuator is the most sophisticated device suitable for all applications demanding high performance. The A-AF series come with your choice of different connector terminations, including FC, SC, or ST compatible connectors. With the patented mode filter design, the A-AF series can enhance mode stability dramatically and be readily panel mounted without any dummy fiber.
- ST is a registered trademark of AT & T.
- Environmentally stable.
- Easy installation.
- Custom defined specifications.
- Low return loss.
- Low insertion loss tolerance.
- Panel readily mountable.
