SAFETY WARNINGS

LASER RADIATION

The OTEA-CO-B EDFA emits invisible radiation that can cause permanent eye damage.

DIRECT EXPOSURE TO BEAM.

the optical connector. Power to the OTEA-CO-B EDFA should be turned off or preferably,
disconnected whenever the optical connector cover is opened and there is no installed fiber (as
when the fiber connector is being installed or removed from the optical connector). When the
amplifier isworking in normal state, theoutput power of lightwith wavelengths in theinvisible range

(

infrared light) may exceed +26dBm (400mW). Therefore, to avoid damaging your eyes, do not

look into the outputport oftheEDFAdirectly.

NEVER

look at the end of the fiber to see if light is coming out Most fiber optic laser
wavelengths (1310nm and 1550nm) are totally invisible to the unaided eye and will cause
permanent damage.Always useinstruments, such asanoptical power meter,to verify lightoutput.

Use extreme carewith ,

NEVER

look intothe output ofthe EDFA or afiber connected toan EDFA

NEVER

clean an optical connectorwith opticalpowerpresent.

NEVER

look into or use any optical instrument to view the distant end of a fiber that may be
connected directly or via an optical splitter, to a transmitter or EDFA that may be operating. This
specifically applies to fibers that are to be connected to receivers (such as the OTPN-2000C) or
other devices at anydistance fromthelasertransmitter or EDFA.

ALWAYS

read the product data sheet and the laser safety label before powering the product
Note theoperation wavelength, optical outputpower and safetyclassifications. If safetygoggles or
other eye protection are used, becertain that the protection is effective at the wavelength emitted
by the device undertest applying power.

ALWAYS

connect a fiber to the output of the device power is applied. Power should
never be appliedwithout an attached fiber.Ifthe device has aconnector output, a connector should
be attached that is connected to a fiber. This will ensure that all light is confined within the fiber
waveguide, virtually eliminating allpotential hazard.

The OTEA-CO-B EDFA contains no user serviceable parts. There is exposed high voltage inside
this unit. Only authorizedfactory servicetechniciansshouldopen the unit with power applied.

The OTEA-CO-B EDFA is designed for indoor use only. Direct exposure to moisture must be
avoided. Ifyouhavequestions about laser safety procedures,please call Olson Technology before
powering your product. The fiber amplifier is sensitive equipment. Do not open the case of the
amplifier to avoid damaging the internal component devices. Opening the case of the amplifier
without the written permissionof OlsonTechnology,Inc., will void the warranty.

Operate the EDFAonly with the proper optical fiber installed in

INTRODUCTION

Olson Technology, Inc. provides a wide range of Erbium Doped Fiber Amplifiers
(EDFA’s), for 1550nm HFC networks that feature low noise figure, stable output power
and excellentenvironmental stability. EDFA’s are comprised of two main parts:the gain
module andthe externalcontrol system.The gainmodule amplifies the optical signal in
1550nm wavelength band (1540-1560nm typically). It is made of high quality optical
components, and carefully designed to maximize overall performance. Low power

'

EDFA s may only have a single pump, while high power units can have up to three
pumps. Theexternal control system allows the operator toensure that the gain module
is working optimally Controlled by microprocessor it monitors the states of the gain
module and adjusts all the parameters to ensure a stabilized output power of the gain
module. This system also provides warnings via the front panel indicator LED and a
digital display The LCD on the front panel shows the detailed working parameters of
the EDFA This information can also be accessed via the standard RS 232 interface
via an externalcomputer.
