Erbium Ytterbium Doped Fiber Amplifier, 33 dBm (EYDFA-33-R)

Data Sheet

Product Overview

The Optilab EYDFA-33-R Erbium Ytterbium Doped Fiber Amplifier (EYDFA) is a high-power, versatile amplifier designed for CATV networks, optical communication and other general-purpose optical applications. Based on multi-mode pumping Er/Yb double clad fiber technology, EYDFA-33-R is designed to produce high output power up to 33 dBm. By using a dual stage design, EYDFA-33-R provides optical gain of up to 50 dB (with optional Pre- Amp), while maintaining low noise figure (NF) below 5 dB. The EYDFA-33-R amplifier produces optical output level of +33 dBm with an input power level range from -3 dBm to +7 dBm. Featuring adjustable output level power via ACC through the front panel and software control through USB, this compact 1U-housing can provided up to 32 output ports. Contact Optilab for more information.
