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.

Flat High-Power Broadband Sources

ST-EBS-4022, ST-EBS-4022L, ST-EYBS-3527

 

 

ST-EBS-4022

The ST-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.

 

Featuring the same power-spectral density as a full set of 100-GHz spaced DFB lasers, the ST-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 ST-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 ST-EBS-4022, frequent spectrum recording is unnecessary.
