DWDM optical communication systems also contain WDM channels spaced close to 50 GHz (0.4 nm).

In this environment, an optical spectrum analyzer with excellent dynamic range

is required to separate the optical signal and measure the noise figure (NF) of the optical amplifier.

With a dynamic range of 50 dB at 0.1 nm and 60 dB at 0.2 nm,

the Q8384 fully meets these requirements.

The instrument is equipped with an automatic optical amplifier NF measurement and calculation function,

allowing the user to perform the measurement in a simple manner.

The Q8384 can be optionally equipped with a built-in reference wavelength light source and an EE-LED (Edge Light Emitting Diode).

When calibrated with this reference light source,

the instrument ensures wavelength accuracy of 20 pm in the 1550 nm band.

Utilizing the EE-LED’s broadband light source, the Q8384 allows the user to easily measure

and evaluate the transmission and loss characteristics of narrowband filters.
