| ■製品概要／Product Overview | |
| The EBS-4022 Erbium Broadband Source is an extremely stable, flattened broadband source delivering 22 dBm in a 40-nm wide spectrum spanning the whole Erbium C band. It utilizes amplified spontaneous emission (ASE) from diode-pumped Erbium-doped fiber and a spectral shaping scheme which flattens the output to better than 1 dB from 1527 to 1567 nm. | |
| ■特徴／Key Features |
Featuring the same power-spectral density as a full set of 100-GHz spaced DFB lasers, the EBS-4022 can dramatically reduce equipment costs in a variety of telecommunications test sets. As a powerful, flat source, it also naturally lends itself to local networking using spectral slicing or optical code-division multiplexing. The very high power of the EBS-4022 provides an unsurpassed, uniform dynamic range for the characterization of passive optical components such as array waveguides. Testing is quick and precise, and with the remarkable spectral stability of the EBS-4022, frequent spectrum recording is unnecessary. |
| ■アプリケーション／Application |
| Wide-dynamic-range characterization of components such as AWGs and FBGs Alternative to multiple DFB lasers and multiplexer in telecommunications test sets Accurate gain-spectrum measurement of EDFAs with spectral-hole burning included Local networking using spectral slicing or optical code-division multiplexing PMD measurements of long-span fiber links Fiber sensing Gyroscopes White-light interferometry |
