XOA-1700-R20 / XOA-1700-R10 Optical Spectrum Analyzers

The XOA-1700 Series measures optical power as a function of wavelength across 600 to 1700 nm. It is intended for optical communications, active and passive photonic devices, component production, and laboratory characterization. Selectable wavelength resolution, five sensitivity settings, fiber and free-space input, and application-specific analysis tools allow the same platform to move between weak-signal inspection and higher-power component testing. One XOA-1700 platform spans a 1100 nm full-range sweep across visible-edge, near-infrared, and optical-communications wavelengths. XOA-1700 free-space optical input extends the platform to devices and optical paths that are not conveniently fiber-coupled.

Both XOA-1700 models share the 600 to 1700 nm wavelength range, sensitivity limits, +20 dBm per-channel input limit, +25 dBm total safe-input limit, 35 dB optical return loss with an APC connector, supported fiber types, and free-space optical input. Their main documented differences are resolution, zero-span capability, sample-point capacity, wavelength performance, and model-specific dynamic-range values. Select XOA-1700-R20 for resolution down to 20 pm or XOA-1700-R10 for an additional 10 pm setting. XOA-1700-R20 supports up to 50,001 sample points; XOA-1700-R10 supports up to 100,001 points and adds a 0 nm span setting. The main XOA-1700-R10 additions are a 0.01 nm resolution setting, a 0 nm span setting, up to 100,001 sample points, and 80 dB dynamic range at 0.01 nm resolution and ±1.0 nm from the spectral peak.

The XOA-1700 adaptive spectral peak search automatically locates peaks across complex laser and multiplexed spectra, and the XOA-1700 automated peak search is designed for accurate, robust, and fast detection across complex optical spectra. XOA-1700 single-longitudinal-mode laser analysis uses threshold and side-mode suppression ratio analysis to evaluate centre wavelength, spectral bandwidth, and SMSR for DFB-LD and related sources, and XOA-1700 multimode laser analysis uses n-dB loss, envelope, and RMS methods to provide complementary centre-wavelength and bandwidth measurements for FP-LD and related sources. XOA-1700 one-touch and batch processing application workflows support LED, FP-LD, DFB-LD, and LD-module testing with batch processing of selected measurement items.

The XOA-1700 Series also covers spectral characterization of optical amplifiers and fiber amplifiers across the communications bands, LED, FP-LD, DFB-LD, LD module and optical transceiver spectrum measurement, and measurement of optical fibers, fiber gratings and other passive devices within the supported wavelength range.

The XOA-1700 built-in SLED source option provides at least 1 mW output and 1550 nm centre wavelength. The XOA-1700 SLED source with C2H2 absorption cell provides at least 1 mW output and 1550 nm centre wavelength. The XOA-1700 GPIB and trigger I/O option provides a GPIB interface, trigger input, and trigger output. The XOA-1700 English interface configuration provides English-language front and rear panels with an English operating system.

The XOA-1700 sensitivity coverage ends at 1620 nm even though the instrument wavelength range extends to 1700 nm. No sensitivity value is claimed here for 1620 to 1700 nm.

XOA-1700 dynamic range depends on both wavelength resolution and distance from the spectral peak; XOA-1700-R20 entries are guaranteed values. The absence of XOA-1700-R10 values at 0.02, 0.05, and 0.1 nm does not mean zero performance. Those conditions remain unclaimed until model-specific released data is available.

At 1550 nm, the XOA-1700 polarization-dependence value is ±0.08 dB for both models; the XOA-1700-R20 value is specified with wavelength resolution of at least 0.05 nm. At 1310 nm, XOA-1700-R20 is specified at ±0.08 dB. No XOA-1700-R10 value is stated at 1310 nm, so none is inferred.

Choose XOA-1700-R20 when 20 pm minimum selectable resolution and up to 50,001 points meet the measurement plan. Choose XOA-1700-R10 when the DUT requires a 10 pm minimum selectable resolution, a 0 nm span setting, or up to 100,001 sample points.

The detailed XOA-1700 chassis and option data is specifically for the XOA-1700-R20 configuration. It lists a 12.1-inch touch screen, 128 GB storage, USB and Ethernet, VGA availability by configuration, 100-240 VAC at 50/60 Hz, maximum power consumption of 100 W, operation from 5-35 °C at up to 80% RH, and a performance-guarantee temperature of 18-28 °C. The chassis size is (426 ±4) × (221 ±2.5) × (450 ±4) mm W × H × D, with an approximate weight of 20 kg.
