* CW output power is defined as the highest possible optical output power that the
laser source can produce at the output connector
† For power levels at "LOInput" ≤ 20 dBm
Please pay attention to the following laser safety warnings:
• Under no circumstances look into the end of an optical cable attached to the
optical output when the device is operational. The laser radiation can
seriously damage your eyesight.
• Do not enable the laser when there is no fiber attached to the optical output
connector.
• The laser is enabled by the software. The laser is on when the green LED
above the LO Output connector is lit.
• The use of the instruments, such as microscopes or spectacles, with this
product will increase the hazard to your eyes.
• The laser module has built-in safety circuitry which will disable the optical
output in the case of a fault condition.
• Refer servicing only to qualified and authorized personnel.
