2.1.2 Laser Sources
The S320 OCS generates Class 1 laser light, but it passes higher-powered laser light from external
sources. The switch passes laser light through its fiber terminations when traffic-carrying fibers
are connected to the switch.
2.1.2.1 Class 1 Laser
The S320 OCS uses a Class 1 laser internally as a test source. Light from this laser could
potentially be available at a fiber termination.
The S320 OCS is certified as a Class 1 laser product per the requirements of the U.S.
Federal Product Performance Standard for Laser Products contained in the regulations
in 21 CFR 1040.10. Class 1 laser products are not considered to be hazardous;
however, lasers more powerful than Class 1 may be connected to the S320 OCS.
Although the S320 OCS has no laser sources higher than Class 1, the total optical
power through the equipment—and potentially available at any one of the fiber
terminations, split-out cable connectors, patch-panel cables or patch-panel coupling
sleeves—could aggregate to the level of a Class 4 (highly hazardous) source.
2.2 Electrostatic Discharge
System components that contain integrated circuits can be damaged by static electricity. Static
electricity potentials develop through the movement of human bodies and are released as
Electrostatic Discharges (ESDs) whenever they come in contact with other objects. Dry air
allows greater static charges to accumulate, but because potentials high enough to damage
circuits can occur anywhere, taking precautions against ESD is imperative when working around
the S320 OCS.
The ESD symbol shown here appears on packaging and other items as a reminder to
take the necessary precautions to prevent electrostatic damage to the S320 OCS.
