Safety and Fiber Optic Systems
Optical Fiber Safety
Never look directly into the end of the optic fiber while either end of the system is
operating.
This Telethon 3G contains CDRH Class 1 laser devices. To prevent damaging your eyes,
always avoid looking directly at, or staring into, the laser light located on an optical
connector or on the end of a fiber.
Infrared radiation is produced at the fiber connection port on the rear of the TX units and at
the end of any un-terminated optical fibers that are attached to this port. Avoid any direct
exposure to the light that comes from these sources.
Do not power up the unit when no fiber is attached to the fiber port.
There are no user adjustments inside the Telethon 3G. Do not attempt any type of service to
this instrument other than any as instructed this manual. Refer all servicing to the Grass
Valley (see
Contact Us on page 25).
Always use cable connector caps when the cables are not connected. This protects the
connector from damage and the unlikely event of exposure to an operating optical link.
Keeping the caps in place when the connectors are not in use will prevent dirt and dust
from entering the connector and degrading the performance of the optical link.
