Note
The AT-iMG646BD-ON WAN module has a receive sensitivity of -3
dBm to -32 dBm at 1550 nm. After the fiber pigtail is installed and
before you plug the pigtail into the gateway, please check the power
of the optical input signal. The power at 1550 nm should fall within
the receive sensitivity specification. If the power is too high, an
optical attenuator is needed in the link. If the power is too low, you
must trace the optical path to determine the cause of the excess
loss.
Note
The AT-iMG646PX-ON WAN module has a receive sensitivity of -3
dBm to -26.5 dBm at 1490 nm. After the fiber pigtail is installed and
before you plug the pigtail into the gateway, please check the power
of the optical input signal. The power at 1490 nm should fall within
the receive sensitivity specification. If the power is too high, an
optical attenuator is needed in the link. If the power is too low, you
must trace the optical path to determine the cause of the excess
loss.
