Product Overview:

High Power EDFA Overview:

This very high power EDFA instruments as a 1550nm range C-band erbium (20 Watt) doped fiber amplifier that delivers up to 20 Watts of output power. They are simple to operate, affordable rack-mounted 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 in ACC mode. ACC mode is "current control" to the pump lasers. The optional 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 adjusts EDFA settings through a 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 high power EDFA's offer an extensive array of protection features designed to protect the amplifier from accidental user-induced damage, and also 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 interlock to allow the user to set conditional shut-down conditions for the amplifier, and the rack-mounted amplifiers include a big red emergency-stop button on the front panel.

EDFA Utilizes Telcordia Qualified High Reliability Components:

These EDFA's employ highly-reliable Telcordia qualified 976nm pump lasers, as well as Telcordia qualified combiners. The principal of operation is the light from the pump lasers excites the erbium and/or ytterbium ions embedded in the fiber from their ground state to achieve the resultant high excitation levels. The high-energy decays to amplify signal light, in the C-band range, and thus amplifies the input signal. 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.
