The Q8384 Optical Spectrum Analyzer measures and evaluates ultra-high-speed optical DWDM transmission systems and optical components with high wavelength resolution and high accuracy.

The new high-end optical spectrum analyzer utilizes a new four-pass monochromator system to provide high wavelength resolution and wide dynamic range.

● 10 pm resolution bandwidth

● 20 pm wavelength accuracy (using Opt.)

● Wide dynamic range: 50 dB (±0.1 nm), 60 dB (±0.2 nm)

● Optical frequency display

● Accurate NF measurement of EDFAs

● Handles power levels up to +23 dBm (200 mW)

● Rich WDM analysis functions

● Provides limit line function for pass/fail analysis

In DWDM optical communications, accurate wavelength measurements of light sources are required. Evaluating these specifications requires optical spectrum analyzers with higher resolution bandwidth and wavelength accuracy.

To meet these stringent requirements, the Q8384 has the world’s highest wavelength resolution of 10 pm* and wavelength accuracy of 20 pm.

It also achieves 20 pm wavelength accuracy in the 1550 nm band. This high performance enables the Q8384 to accurately measure the oscillating wavelength characteristics of laser diodes.

DWDM optical communication systems also include wavelength division multiplexing channels.

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.
