EDFA; Full C-Band; 2 Watt Output Power
- Polarization-Maintaining Amplifier

Product Overview:

High Power EDFA Overview:

These high power EDFA instruments are 1550nm range C-band erbium doped fiber amplifiers delivering up to 2 Watts of output power. They are easy to operate, affordable benchtop instruments for laboratory research or manufacturing test applications. These units provide full control over the power and gain through user control of the internal 976nm pump laser diode current levels, or by setting the instrument into a gain feedback or power feedback mode. The default / standard product offering comes with ACC mode (current control to the pump lasers), and APC mode can be ordered as an option to allow automatic power-feedback control mode.

Flexible User Interface Options:

The user adjusts the instrument settings via the front panel with an intuitive menu and control knob. Settings can also be made by remote interface. These units include RS232 standard, and an ethernet interface can be ordered as an option. LabVIEW based control software is included free of charge. Please contact us if you would like to view the Operating Manual or see the remote interface command set.

Extensive Integrated Amplifier Protection Features:

These high power EDFA's offer an extensive array of protection features. Integrated protection features are designed to protect the amplifier from user induced damage as well as protect the user from harm. They offer an input laser power detection circuit which automatically shuts down the internal 976nm laser diode pumps. They also offer current and voltage limits for the pump lasers as well as (TEC) over-temperature shut-down. The chassis is equipped with a BNC interlock to allow the user to set conditional shut-down conditions for the amplifier.

EDFA Utilizes Telcordia Qualified High Reliability Components:

These EDFA's utilize high power and high reliability Telcordia qualified 976nm pump lasers as well as Telcordia-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 30 dB. Because they are polarization maintaining amplifiers, they amplify the light polarized along the slow axis of the fiber. The EDFA includes optical 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 dB with a very flat gain profile over the C-Band make these instruments ideal for many applications.

Additional models of polarization-maintaining EDFA are available, with output powers up to 10 Watts.
