The AQ6370E is the new model in Yokogawa’s most popular telecom class OSA. With a versatile wavelength range of 600 nm to 1700 nm, it is ideal for both telecom and general purpose applications. The unique free-space input design allows him to test both DWDM-class single-mode and VCSEL-sourced multimode fibers in one single model.
The new high-speed measurement mode, high close-in dynamic range mode, touch panel, and APP function greatly improve measurement efficiency.

| Wavelength range | Standard (-10) | High performance (-20) |
|---|---|---|
| 1520 to 1580 nm | ±0.015 nm | ±0.008 nm |
| 1450 to 1520 nm 1580 to 1620 nm | ±0.015 nm |
Note: The wavelength accuracy values in the table are typical values.
Ultra-High Dynamic Range: 78dB typ.
With the reduced stray-light in the monochromator, AQ6370E achieves ultra-high dynamic range of typ. 78dB.
| Standard (-10) | High Performance (-20) | |
| Peak± 1.0 nm Peak± 0.4 nm Peak± 0.2 nm | 73 dB 62 dB 45 dB | 73 dB (Typ.78dB) 64 dB (Typ.70dB) 50 dB (Typ.55dB) |

Sharper spectrum measurement: HCDR mode
The HCDR (High Close-in Dynamic Range) mode is a feature for single longitudinal mode laser measurements that makes the spectrum around the peak sharper and the side modes more clearly visualized.
This mode is only available on the High performance model(-20).
Example of HCDR mode

Sensitivity setting: MID
High dynamic mode: ON, typical
Wide Level Range: +20DBm to -90dBm
The AQ6370E 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.- AQ6370E’s low insertion loss for multimode fiber is also beneficial to maintain the excellent measurement efficiency.
Multimode and single mode fiber on the same OSA.- 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.
Up to 2x faster SMSR measurement: SMSR mode
The SMSR mode is the sensitivity setting dedicated for measuring the laser’s SMSR faster.
It can measure the SMSR up to twice as fast as the conventional sensitivity mode (TRAD MIDx2).
Note: Fast measurement may not be possible depending on the level of the optical spectrum.
Fast Remote Interface (Ethernet, GP-IB)
Wide Span Sweep yet High Resolution
The 20,001 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.
Large touchscreen LCD
The high-resolution, responsive 10.4-inch multi-touch capacitive touchscreen makes device operation even simpler and more intuitive. You can change measurement conditions, perform analysis, change the optical spectrum view as if you were operating a tablet device. In the optical spectrum view, the waveform view can be zoomed or shifted by a simple tap and drag.
USB ports
Four USB ports in total available on front and back facilitate the use of external devices such as a mouse, keyboard, external hard drives, and memory sticks.
