EkoLink Plus Fiber Optic DAS
The EMS Wireless laser products are used in optical fiber communications
systems for radio frequency and microwave frequency analog fiber optic
links.
shielded by the hermetically sealed laser metal package. Laser bias current
is limited by the internal control circuitry. The transmitters are coupled to
glass fiber and have 1310/1550 nm optical output wavelength with typically
0.5 to 20 mW output depending on the model. The optical radiation is
confined to the fiber core. Under these conditions, there is no accessible
laser emission and hence no hazard to safety or health.
Since there is no human access to the laser output during system operation,
no special operator precautions are necessary when fiber is connected to the
transmitter and receiver. During installation, service, or maintenance, the
service technician is warned, however, to take precautions, which
include not looking directly into the fiber connector or the fiber that is
connected to the fiber connector before it is connected to the fiber
optic receiver. The light emitted from the fiber optic connector or any
fiber connected to the connector is invisible and may be harmful to the
human eye. Use either an optical power meter or an infrared viewer or
fluorescent screen for optical output verification.
precautions as outlined by the FDA and ANSI Z136.2 and other
authorities of class IIIb lasers must be observed.
Do not attempt to modify or to service this Product. Contact the EMS
Wireless Customer Support Department for a return authorization if service
