Stray-light suppression ratio: 80dB typ.

This new specification provides stray-light suppression capability when High dynamic mode, usually taking longer measurement time, is not used. The AQ6370C contributes to shortening the measurement time with the high stray light suppression ratio.

Wide Level Range: +20DBm to -90dBm

The AQ6370C can measure high power sources such as optical amplifiers and pump lasers for Raman amplifiers, and very weak optical signals as well. Measurement sensitivity can be chosen from seven categories according to test applications and measurement speed requirements.

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.
AQ6370C'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.

Excellent Efficiency

Fast Sweep: 0.2sec./100nm

With an advanced monochromator, faster electrical circuits, and noise reduction techniques, the AQ6370C achieves fast measurement speed even when measuring a steep spectrum from DFB-LD or DWDM signals, or when measuring a low power signal from a broadband light source.
