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. In normal operation, these systems are fully enclosed and fully

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. All handling

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

or repair is necessary.
