Ando AQ6317 Data Sheet

Optical Spectrum Analyzer

AQ6317

High-resolution optical spectrum analyzer for
evaluating D-WDM systems and components.

High-resolution optical spectrum ana
D-WDM systems and components.

General

The AQ6317 is an advanced optical spectrum analyzer
for a wide range of applications, including light source
evaluation, measurement of loss wavelength character­istics in optical devices, and waveform analysis of WDM
(Wavelength Division Multiplexing) systems.

Especially at 1550 nm band, the unit achieves high
wavelength accuracy and wavelength linearity, and can
evaluate optical devices for WDM. Analysis functions
make operation and expandability simple.

The AQ6317 contains the latest of Ando’s technology for
optical spectrum analyzers. Areference equipment for
the next generation.

Features

● 50 GHz WDM-Signals

High-resolution measurement in a wide 50 GHz spec­trum dynamic range.

● Versatile analysis functions

Analysis functions for WDM and other optical devices
(LD, LED, FBG, etc.)

● High wavelength accuracy

Provides ±0.05 nm wavelength accuracy in the 1550 nm
band, with ±0.01 nm wavelength linearity, making it
especially useful for high-precision loss wavelength
characteristic and other evaluation of WDM devices.
The wavelength scale indicates both in air and in vacu­um.

● Synchronous sweep

In conjunction with a AQ4320 Tunable Laser Source,
much higher wavelength resolution/wide dynamic range
can be achieved by high-speed synchronous sweep.

● High wavelength resolution

Achieves wavelength resolution of 0.015 nm

● High sensitivity over a wide band

Covers from 600 nm to 1750 nm and high sensitivity
allow measurement of light at down to -90 dBm.

● Low polarization dependancy

Measurements such as gain of optical amplifier can be
proceeded accurately because polarization dependen­cy is suppressed as low as ±0.05 dB.

● High-level accuracy

Accurate within a ±0.3 dB.

● High power measurement: Max. +20 dBm (100 mW)

Even high-power output from an optical amplifier can
be measured directly without an optical attenuator.

● 9.4-inch color LCD

● Pulsed light can be measured

● Three individual trace memories

Applications

Measures transmission characteristics of 16-channel AWG and displays
results on AQ6317’s screen.

● Optical fiber amplifier (EDFA) evaluation

The ASE interpolation method is used to measure gain
and NF, key parameters for optical fiber evaluation.
In conjunction with the AQ8423A/8423B optical amplifi­er analyzer, the system can accurately measure gain
and NF with the pulse method, which is optimum for
evaluation of WDM optical fiber amplifiers.

● Optical Multiplexer evaluation

In conjunction with the AQ4320 Tunable Laser Source,
the AQ6317 can achieve high wavelength
resolution/wide dynamic range with high-speed syn­chronous sweep function, and result insertion loss,
passed central wavelength and linearity as evaluation
parameter of optical MUX/DEMUX.
