Name: XOA-2400 / XOA-2500 Series Optical Spectrum Analyzers
Brand: XGY Tek

Overview

XOA-2400 covers 1200–2400 nm and XOA-2500 covers 1000–2500 nm. Both are grating-based optical spectrum analyzers with standard 0.05–2 nm resolution settings for telecom, extended-NIR and SWIR tests.

Additional product details

XOA-2400 covers 1200 to 2400 nm; XOA-2500 extends coverage to 1000 to 2500 nm.

The XOA-2400 / XOA-2500 12.1-inch touch interface and integrated analysis functions support LED, FP-LD, DFB-LD, optical-transceiver, DWDM, amplifier, fiber, grating, SWIR, sensing, and medical measurement workflows. On the XOA-2400 / XOA-2500 Series, a 0.002 nm minimum sampling interval and up to 50,001 points support detailed spectral capture, and free-space input and support for single-mode, graded-index, and large-core fibers accommodate diverse optical paths. The XOA-2400 / XOA-2500 Series also measures optical fiber, fiber gratings, and other passive optical components across the applicable model range.

Both XOA-2400 / XOA-2500 models have a 50 pm minimum standard setting: both models provide 0.05, 0.1, 0.2, 0.5, 1, and 2 nm resolution settings in the standard configuration. The XOA-2400 / XOA-2500 0.05 nm minimum standard resolution is the smallest of six standard resolution settings from 0.05 to 2 nm that both models share.

External-source calibration and optical-axis alignment on the XOA-2400 / XOA-2500 Series are supported when the gas-absorption-cell calibration-source option is not fitted. Specifications do not establish that calibration source as standard equipment.

Key Capabilities & Applications

Model-selected wavelength window

Choose 2400 or 2500 for the required spectral edges. Both provide 0.002 nm minimum sampling interval and 101–50,001 points plus AUTO.

Conditioned optical performance

HIGH3 sensitivity is −65 dBm at 1800–2200 nm, with separate neighboring-band limits. Wavelength accuracy is ±0.05 nm at 1520–1580 nm and ±0.50 nm across the selected model's full range.

Flexible input and calibration

Free-space input and single-mode, graded-index and large-core fibers up to 200 µm are supported. External-source calibration/alignment applies when the gas-absorption-cell calibration-source option is not fitted.

Performance notes

On the XOA-2400 / XOA-2500 Series, the -65 dBm figure applies only from 1800 to 2200 nm in HIGH3; adjacent bands have separate limits. Unspecified edge bands are not treated as zero and are not filled by extrapolating adjacent values.

The interval-specific accuracy values are not extended beyond their stated bands. The ±0.50 nm figure is the full-range value for each selected model. XOA-2400 / XOA-2500 dynamic-range values are tied to 1523 nm, 0.05 nm resolution, HIGH1 to HIGH3, and specific peak offsets.

Specifications are subject to change without notice.

Model selection details

Choose XOA-2400 for 1200 to 2400 nm coverage. Choose XOA-2500 when the test window must extend down to 1000 nm, up to 2500 nm, or across both extended edges. The family description does not mean that XOA-2400 covers the complete 1000 to 2500 nm span. Wavelength range, sensitivity coverage, and conditioned performance must be checked separately.

Scan span is 0.5 to 1200 nm (XOA-2400) or 0.5 to 1500 nm (XOA-2500).
