■メーカーの紹介 |
| ■製品概要／Product Overview | |
| A new series of high-power spectrally-sliced Erbium Broadband Sources | |
| ■特徴／Key Features |
| A cost-effective way of simulating DWDM signals, replacing costly banks of DFB lasers. Greatly reduces experimental set up and maintenance time. Features the same power-spectral density as a full set of DFB lasers. 50 GHz spacing allows simulation of > 80 channels in the C band (100 GHz spacing also available). Channels locked to ITU grid. High peak-to-valley extinction ratio (> 47 dB). High stability. Also available in L-band.  |
| ■アプリケーション／Application |
| Simultaneously measure optical amplifier gain flatness and noise figure under conditions of full channel loading (high peak-to-valley extinction ratio extends NF measurement capability to high-power booster amplifiers). Measure full C-band OSNR evolution over links consisting of multiple spans and optical amplifiers without the need for costly banks of DFB lasers. Measure magnitude of inter-channel Raman pumping along a span for fully-loaded C-band case. Drop one or more peaks and insert data carrying channels to make BER measurements in transmission systems under conditions of full channel loading. Test DWDM demux components. |
