The EBS Series of erbium-doped fiber broadband sources is designed for use either as test instruments or transmitters for a variety of DWDM applications. The sources use reshaped amplified spontaneous emission from erbium-doped fiber to provide a broadband output. The fiber is pumped by three 170-mW diode lasers at 980 nm. The output is unpolarized and centered around 1550 nm. The EBS4022 transmitter-type source features an output flat to 1 dB from 1527 to 1567 nm. Telecommunications applications include characterization of high-loss components, EDFA and telecommunications links testing, optical-code division multiple access, and local networking by spectral slicing. The sources are equipped with an output isolator.
