Light Source Module for optical Test System

Yokogawa AQ2200 11206 February 2019 - Yokogawa Test & Measurement launched the AQ2200-112 light source module for the AQ2200 series multi-application test system. This new light source module features extremely high output level stability and is ideal for use on production lines in the testing and inspection of the optical fibers, optical connectors, optical isolators, and other components used in optical communication networks.

Explosive growth in the use of the Internet, smartphones, and other devices and the increasing reliance on cloud-based services, digital terrestrial TV broadcasting, and the like is driving demand for optical fibers, optical connectors, passive optical components such as optical isolators, and other components used to construct optical communications networks. On the production lines where these optical components are manufactured, light sources with high output stability are required to evaluate their optical loss characteristics. To satisfy this need, Yokogawa has developed the AQ2200-112 light source module.

Excellent optical output stability for the measurement of optical loss

The AQ2200-112 achieves a stable optical output of ±0.005 dB. This is accomplished by regulating the temperature of the emitting device, suppressing the influence of reflection from the device under test, and compensating for the fluctuations caused by interference. This light source ensures excellent stability of the output level and thus is suitable for evaluating loss in optical components.

Four different versions of the AQ2200-112 are available that cover the commonly used wavelengths of 1310 nm, 1550 nm, 1625 nm, and 1650 nm.

Easy construction of optical loss measurement systems

To measure optical loss, a light source and sensor are needed. In addition, when performing such measurements at different wavelengths, an optical switch is required. With the AQ2200 series, optical sensors, optical switches, and grid tunable light sources have all been available as plug-in modules. The release of the AQ2200-112 fixed-wavelength light source module allows our customers to construct a system using the AQ2200 that is able to measure loss in optical communication components.

A multi-fiber push-on (MPO) connector adapter, which is a fiber connector consisting of multiple optical fibers, and a fiber optic ribbon cable adapter are also available as accessories for use with sensors to measure multi-core connectors, fiber optic ribbon cables, and the like.
