Optical Fiber Safety
Never look directly into the end of the optic fiber while either end of the system is
operating.
These devices contain 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 manual adjustments to be made in these devices. Do not attempt any manual
type of service to this instrument, other than any as instructed this Guide. Refer all servicing
to Grass Valley
(see Contact Us on page 7 ).
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.
