High Power EDFA Overview:
These EDFA instruments are 1550nm range C-band erbium doped fiber amplifiers which offer up to 0.21 Watt of output power at 1 mW input power. They are simple to operate, affordable benchtop instruments for laboratory research or manufacturing test applications. The user has full control over the power and gain through by controlling the internal 976nm pump laser diode current (ACC mode), or by setting the instrument into a gain feedback or power feedback mode. (APC mode).
Flexible User Interface:
The user adjusts EDFA settings via the front panel with an intuitive menu and control knob. Settings can adjusted by RS232 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 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 inputsignal detection circuit which automatically shuts down the current to the internal 976nm laser diode pumps if the input signal goes to zero. They also offer current and voltage limits for the pump lasers as well as (TEC) over-temperature shut-down. Both 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.
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 that laser light from the pump lasers 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. Each high power EDFA unit has 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 < 5 dB with a very flat gain profile over the C-Band make these instruments ideal for many applications.
