(–3100 to
–1500)
Read-write Notifies operations personnel
if the optical input signal of the
ONS 15216 EDFA2 drops
below a level that impacts
proper operation of optical
network. Set this attribute at a
value that is appropriate for the
intended application so that the
alarm condition is meaningful.
Consult with a Cisco Systems
Engineer to determine the
threshold value for your
application. As a guideline,
Cisco recommends setting the
threshold value at 3 dBm
below the current input power
level of the amplifier. Valid
entries are between –3100 and
–1500 dBm times 100. For
example, if the total input
power of the amplifier is –24
dBm and the loss of input
power threshold required is
–27 dBm, the loss of input
power alarm threshold is
–2700.
