Superior Fundamental Performance

10 pm High Wavelength Resolution The Q8384 achieves a wavelength resolution bandwidth

of up to 10 pm by using a newly developed monochromator system.

This makes it possible to measure and evaluate the sidebands of 10 Gbps intensity-modulated optical signals,

a task previously impossible with conventional spectrum analyzers.

20 pm high wavelength accuracy

Calibrated with the built-in calibration light source (option 25), the Q8384 achieves wavelength

 measurement accuracy of ±20 pm in the C-band wavelength range from 1530 to 1570 nm.

The Q8384 achieves wavelength measurement accuracy of ±20 pm in the

C-band wavelength range of 1530 to 1570 nm and ±40 pm in the L-band wavelength range of 1570 to 1610 nm.

It enables accurate characterization of laser diodes and filters used in DWDM transmission systems.

The Q8384 can also accurately measure the wavelength spacing of WDM signals

because of its ±10 pm wavelength linearity over the 1530 to 1570 nm wavelength range.

50 dB (±0.1 nm)/60 dB (±0.2 nm) Wide Dynamic Range

In DWDM systems, signals need to be WDMed at intervals of 50 GHz (0.4 nm) or less.

Separating and measuring these closely spaced signals requires an optical spectrum analyzer with excellent dynamic range.

The Q8384’s dynamic range of 60 dB or more at 0.2 nm makes it ideal for this task.

With a dynamic range of 50 dB or more at 0.1 nm, the instrument can support future DWDM systems with closer signal spacing.

+23 dBm (200 mW) high-power direct input The Q8384 can directly measure high-power

signals from fiber amplifiers or pump laser diodes without attenuation.
