AQ2200-342 Optical Attenuator Modules

Compact and lightweight optical variable attenuator with built-in optical power meter

Yokogawa AQ2200-342 Dual Attenuator Module

Features

  • Compact: The AQ2200-342 features an optical variable attenuator and an optical power meter for monitoring the optical output power in a one-slot module. Ideal for bit error testing
  • Compatible with SMF (core diameter of 10 µm) or MMF (core diameter of 62.5 µm)
  • Attenuation accuracy: within ±0.1 dB
  • With the output monitoring function, the AQ2200-342 allows direct setup of optical power at the output terminals
  • Can be combined with various AQ2200 series modules or other Yokogawa’s optical communication measuring instruments to build versatile measuring systems

Applications

  • Optical fiber amplifier measurement system

Description

AQ2200-342 DUAL ATTN is single slot module equipped with two optical variable attenuators. It has built-in optical power meter for monitoring output power with an APC function which keeps constant optical output and simultaneously set the absolute value of arbitrary optical output. In addition, it also features shutter function which shuts off optical output. This module is effective in saving space on active devices such as optical amplifiers and optical transceivers, and also on optical transmission equipment testing and inspection systems.
