C-Band EDFA; Adjustable Output Power up to 2 Watts

Product Overview:

High Power EDFA Overview:

These high power EDFA instruments are 1550nm range C-band erbium doped fiber amplifiers which offer up to 2 Watt of output power. They are simple to operate, affordable benchtop instruments for manufacturing test and laboratory research applications. These user has full control of the output power and gain by controlling the internal 976nm pump laser diode current levels, or by setting the instrument into a gain feedback or power feedback mode. The standard product offering comes with ACC mode (Current Control 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 user can adjust the instrument settings by the easy-to-use front panel and control knob, and settings can also be adjusted via remote interface. These units come standard with RS232 connectivity, and an ethernet interface can be ordered as an option. LabVIEW based control software is available and ships 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 array of protection features 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 current to 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. Both of these functions protect the internal pump sources. The chassis is equipped with a BNC safety interlock to allow the user to set 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 and/or ytterbium 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 not polarization maintaining amplifiers, the polarization-dependent gain is very low.

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.

Versatile Product Offering:

These high quality EDFA instruments are offered in a range of output power options, and also with Polarization-Maintaining capability. Inquire for more information, or search on Laser Lab Source
