Yokogawa AQ2200-421 - Optical Switch Module 1 x 2/2 x 2

What are Optical Switches Used For?

Fiber optical switches can make optical fibers more efficient.

How Do Fiber Optic Switches Work?

GE-PON Test System: To evaluate GE-PON systems used for FTTH networks, optical characteristics and IP traffic tests are performed. Since a GE-PON consists of OLTs and multiple ONUs, efficient measurement of multiple ports is required. Utilizing the multiple port AQ2200-4xx optical switch makes it possible to build an efficient automated measurement system by distributing the signal in a custom test network. Since the AQ2200-332 Optical Attenuator is equipped with a monitor power meter, the ONU optical receiving level can be adjusted without changing the fiber connection.

Multicore fiber loss measurement: MPO connector adapter, MT connector adapter and ribbon fiber adapter enable the measurement of the multi-fiber output directly. With the optical switch module, a multi-fiber loss measurement system can be easily configured.

High-Speed Optical Switch

The AQ2200-421 OSW module features two optical switches with low insertion loss and superior switching reproducibility, in a one-slot size module, and allows selection of 1 x 2 or 2 x 2 port configuration according to the application. Moreover, the optical fiber type can also be selected between SMF(10/125 µm) and MMF(50/125 µm, 62.5/125 µm), allowing a wide range of measuring systems to be built corresponding to the systems or devices used in optical public networks or optical LANs.

Examples of Measurement Application

• For measuring multiple objects, with switching of the object to be measured
• For measuring device characteristics, etc. by switching multiple measuring instruments
• For building a measurement system in combination with a bit error tester, etc.
