WARNING: It is possible for moisture to enter the cable due to damage to the outer protective
layer. This moisture can track down the inside of the cable, filling up the drip loop and
eventually finding its way into the PIDU Plus. To protect against this the outer protective layer
of the cable can be opened up at the bottom of the drip loop to allow this moisture to escape.
WARNING: Some network operators employ gel filled cables to get around the problem of
moisture ingress and transmission. The PTP 400 Series Bridge has NOT been tested using
these cables. Use of gel filled cables may affect the performance of PTP 400 Series Bridges.
