Minimum curvature of the fiber
The minimum radius for sending and reading of the optical signal through the fiber, must be
greater than or equal to 50mm. A curvature with radius smaller, in addition to causing damage
to the fiber with the inevitable replacement of the same, will dramatically reduce the
transmission and reception of the signal, causing alarm cut fiber signaling.
The optimal reading of signal through the fiber, is calibrated to a maximum length of about
200m. If you use longer lengths, the transmission / read signal may be less than the threshold
value set on the concentrator module. In this way will be possible false alarm cut fiber
signaling. Therefore, the plastic optical fiber (ALM-6008) is supplied in reels of 200 meters.
The fiber can be fixed with cable ties and making sure that all the curves that will be
available during installation, can be as "soft" (50mm radius).
