Parameters & Specifications
Category Specification
Model AQ6375
Type Bench-top Optical Spectrum Analyzer
Wavelength Range 1200 to 1750 nm
*This extended range fully covers the S, C, and L-Band (1565-1625 nm), and extends further to 1750 nm, which is critical for characterizing ultra-long-haul transmission and new optical amplifiers.*
Wavelength Accuracy ±0.02 nm (Typical, at 1550 nm, after auto-calibration)
Wavelength Resolution 0.05 to 2 nm (Programmable)
Resolution Bandwidth (RBW) 0.05, 0.1, 0.2, 0.5, 1.0, 2.0 nm
Dynamic Range 75 dB (Typical, peak at ±0.5 nm offset)
55 dB (Typical, peak at ±0.1 nm offset)
Sensitivity -80 dBm (at 1550 nm, RBW = 0.1 nm, Sample Average)
Sweep Speed ~0.4 sec/sweep (for 50 nm span, RBW = 0.1 nm, Auto)
Level Accuracy ±0.3 dB (Typical)
Polarization Dependency ±0.05 dB (Typical)
Input Port FC/PC connector (Standard). FC/APC is optional.
Input Power Level +20 dBm (Maximum total input power)
Display Large, high-resolution LCD with intuitive touch interface.
Data Output USB memory stick support, Ethernet (LAN), GPIB (optional).
Applications Long-haul/ultra-long-haul DWDM system testing, L-Band EDFA characterization, Raman amplifier testing, optical component testing beyond the C-Band.
