High Power EDFA Overview:
These 1550nm-range high power EDFA instruments are erbium-doped fiber amplifiers delivering up to 2 Watts of output power. They are affordable and easy to operate benchtop instruments for laboratory research or manufacturing test applications. These amplifiers allow full control over the power and gain through control of the internal 976nm pump laser diode drive current levels (ACC mode), or by setting the instrument into a gain feedback or power feedback mode (APC). The standard product comes allows ACC mode, and APC mode can be ordered as an option. APC mode allows the user to set a target output power and the instrument will automatically adjust the current level to the pump lasers.
Flexible User Interface Options:
The EDFA settings are adjusted through an easy-to-use front panel with an intuitive menu and control knob. The instrument can also be controlled via remote interface. These units come with RS232 in the standard product offering, and an ethernet interface can be ordered as an option. LabVIEW based control software is available and ships free of charge. Contact us if you would like to view the Operating Manual or see the remote interface command set.
Extensive Integrated Amplifier Protection Features:
These EDFA's include an extensive array of protection features, designed to protect the amplifier from accidental user-induced damage and to protect the user from harm by accidental exposure to high power laser light. They offer an input laser power detection circuit which automatically shuts down the current to the internal 976nm laser diode pumps if the input signal is lost. They also offer current and voltage limits for the pump lasers, as well as (TEC) over-temperature shut-down. Both of these functions protect the internal pump sources. The chassis is equipped with a BNC interlock to allow the user to set conditional shut-down conditions for the amplifier or regulate emergency shut-down externally.
EDFA Utilizes Telcordia Qualified High Reliability Components:
These EDFA's utilize high reliability Telcordia qualified 976nm pump lasers as well as Telcorida qualified combiners. The principal of operation is the laser light from the pump wavelengths and power level excite the erbium ions embedded in the fiber from their ground state to achieve the resultant high excitation levels, and the commensurate high gain levels of up to 33 dB. Because they are polarization maintaining amplifiers, they amplify the light polarized along the slow axis of the fiber. The amplifier includes integrated isolators for the input and the output.
Careful attention to component selection and circuit board design allow these 1550nm range EDFA's to produce high gain at a low noise level. Noise levels of < 6.5 dB with a very flat gain profile over the C-Band make these instruments ideal for many applications.
