Note

The AT-iMG646MOD 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 chassis, 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.
