Olson Technology OTEB-CO-B EDFA WITHOUT SNMP - Manual (Page 3)

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 excellent environmental stability. EDFA’s are comprised of two main parts: the gain
module and the external control system. The gain module 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. The external control system allows the operator to ensure 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 external computer.
