Product Overview:

C-Band DWDM Benchtop EDFA Overview:

These benchtop EDFA instruments are C-band (1529 nm to 1563 nm) erbium doped fiber amplifiers which offer up to 200 mW of output power (23 dBm). They are simple to operate, affordable benchtop instruments for laboratory research or manufacturing test applications.

The C- & L-Band EDFA amplifiers are available in three output power ranges: 17 dBm, 20 dBm, and 23 dBm. All come standard with FC/APC input and output fiber connectors, but can be ordered with others: FC/UPC, SC/APC, SC/UPC. Inquire for details on configuration options for your application. 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, and APC mode can be ordered as an option. ACC mode is "current control" to the pump lasers. 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 EDFA settings through an easy to use front panel with an intuitive menu and control knob. Settings can also be made by 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.

Extensive Integrated Amplifier Protection Features:

These EDFAs offer an 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 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. 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 EDFAs utilize high power and 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 23 dB. Each high power EDFA unit has integrated isolators for the input and the output.
