Important User Information
• Caution: Invisible laser radiation is emitted from the ber output ports, which may cause permanent injury to skin or
eyes.
• Ground rst before turning on the power (Grounding resistance should be less than 4 Ohm), so as to prevent laser
and user from static damaging.
• UPS power supply and air conditioned environment are highly recommended for the stable and long-time transmitter
operation.
