Fibertronics has been officially assessed by NSF-ISR and found to be in conformance to the AS9100 standard.
These are Handheld Optical Variable Attenuators, used for continuously variable optical signal attenuation. The attenuator is primarily used in laser systems and on-line testing, it can therefore can be used in the digital communication devices (such as: PHD and SDH) and in a system of adopting analog modulation (CATV).
