For XG-SFP-ER-SM1550 and XG-SFP-ZR-SM1550, please do not use short-distance fibers for connection to avoid
the overload of the transceiver. If optical power on the receiving end is not lower than -1dBm, a proper optical
attenuator is supposed to be installed onto the end so as to reduce the optical power to lower than -1dBM.
Optical modules generate laser. Do not stare at light source.
