PRODUCT INTRODUCTION

In recent years, progress has been made in the research and development of ultra-high-speed dense wavelength division multiplexing (DenseWDM) optical communications for practical applications. In such research and development

In such research and development, the amplitude characteristics, wavelength dispersion characteristics, and group delay time characteristics of optical devices and optical subsystems are

Amplitude characteristics, wavelength dispersion characteristics and group delay time characteristics of optical devices and optical subsystems are of high optical frequency resolution.

Measurement of amplitude, wavelength dispersion and group delay time characteristics of optical devices and subsystems with high optical frequency resolution is required for such research and development. as test objects,

Examples include AWGs, fibre gratings, filters and dispersion compensators.

Dispersion compensators. In particular, wavelength dispersion characteristics are an obstacle to improving bit rates for optical communications.

The wavelength dispersion characteristic is particularly an obstacle to improving the bit rate of optical communication, and therefore there is a need to reduce or control the wavelength dispersion value.

There is a need to reduce or control the wavelength dispersion value.

The Q7750 Optoscope is an optical network analyser.

The Q7750 Optoscope analyses the transmission, amplitude, wavelength dispersion and group delay time characteristics of optical devices.

The Q7750 Optoscope (Optical Network Analyser) measures amplitude, wavelength dispersion and group delay time characteristics of optical device transmission and reflection characteristics in the optical carrier frequency domain.

The system is an unprecedented optical transmission measurement instrument. Dispersion-shifted fibre, non-zero dispersion

Dispersion characteristics such as zero-dispersion wavelength and dispersion slope of dispersion-shifted optical fibers and non-zero-dispersion optical fibers can also be easily measured.

Measures dispersion characteristics such as zero-dispersion wavelength and dispersion slope of dispersion-shifted optical fibres and non-zero-dispersion optical fibres. The phase shift method is used as the measurement method.

Adopting the phase-shift method as a measurement method provides high optical frequency resolution and wide dynamic range.

ADVANTAGES

High optical frequency resolution

Highest optical frequency resolution: 50 MHz (0.4 pm in wavelength conversion)

The Q7750 has a maximum optical frequency axis resolution of 50 MHz. This makes it possible to measure optical carrier frequencies with ultra-high resolution, which could not be measured before.

This enables measurements in the optical carrier frequency range with ultra-high resolution, which was previously not possible.

Spans from a maximum of 70 nm to a minimum of approx. 0.1 nm.

High-speed measurement

Measurement time: approx. 6.7 ms (per measuring point)

Approx. 4 sec (per set span)

One sweep time (measurement time) is approx. 4 sec. Conventional measurement time of several tens of minutes can be reduced to approx. 4 sec.

The instrument enables measurements that previously took several tens of minutes to be carried out in approximately 4 seconds. Longer measurement times may cause the DUT's characteristics to deteriorate, such as temperature.

The characteristics of the DUT are affected by temperature and other factors, and accurate measurement is not possible with long-time measurements.

Accurate measurement is not possible. The short measurement time of this unit enables high-speed measurement without being affected by the DUT's temperature characteristics, etc.

The instrument's short measurement time enables high-speed, high-precision measurements without being affected by the DUT's temperature characteristics, etc.

Wide measurement wavelength range

Measurement wavelength range: 1525-1635 nm

With the advent of long-wavelength optical fibre amplifiers, the optical communication wavelength range is extending towards the long wavelength side.

The Q7750 supports measurement wavelengths up to 1635 nm.

The Q7750 supports measurement wavelengths up to 1635 nm. This enables the evaluation of optical devices for next-generation optical communication wavelengths.
