DWDM Comb Source
The CombSource is designed to simulate a DWDM signal launched into a fiber link and is an ideal replacement for a costly bank of DFB lasers. It is well-suited for measurements of DWDM amplifier gain and noise figure spectra as well as the evolution of the OSNR and channel power spectra in long-haul, multiply-amplified DWDM systems.
Features
- Replacement for bank of 90 DFB lasers
- Output power up to 22 dBm
- Excellent extinction ratio (>47 dB)
- Channels locked to ITU-T grid of 50 GHz or 100 GHz.
- Units available in both C and L band
Applications
- 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 and channel power 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.
- Test DWDM demux components.
