Анализатор оптического спектра AQ6370D

The AQ6370D is the latest iteration of the most popular Telecom class OSA from Yokogawa. It offers a versatile wavelength range of 600 nm to 1700 nm ideally suited for both Telecommunications and general purpose applications. The unique free space input design allows testing of both DWDM class singlemode and VCSEL sourced multi-mode fibers in one single model.

Newly added functions include data logging, gate sampling,resolution calibration, an advanced marker function and an enhanced auto-sweep mode.

• Improved level sensitivity: -85dBm (1000 to 1300nm)
• Smoothing Function - Reduce noise on the measured spectrum
• High dynamic mode - Obtain a better dynamic range by reducing the influence of stray-light, which is caused when the input is a strong optical signal.

Free Space Input

• Multimode and single mode fiber on the same OSA.

AQ6370D's low insertion loss for multimode fiber is also beneficial to maintain the excellent measurement efficiency.

• Small insertion loss variation at the input

connector increases measurement repeatability.

• No damage connecting fibers

because there is no physical contact.

• APC level correction

The APC level correction function corrects the level offset caused by an insertion loss of angled PC connector.

The 50,001 data sampling points expands measurement range in a single sweep while keeping a high wavelength resolution. This makes your measurement easier and more efficient than conventional systems.
