Exfo IQS-5240S/BP- Optical Spectrum Analyzers

The EXFO IQS-5240S/BP is a optical spectrum analyzer engineered for precise characterization of DWDM, ROADM, and advanced modulation format systems. It delivers sub-picometer resolution, greater than 35 dB dynamic range, and fast measurement times for in-band OSNR and Pol-Mux OSNR analysis up to 400 Gbit/s. The instrument supports comprehensive WDM investigation, laser characterization, and spectral transmittance measurement across the C-band, making it suitable for network commissioning, field validation, and laboratory testing applications. ## Technical Specifications Optical Performance • Wavelength Range: 1520 nm to 1610 nm • Resolution Bandwidth (RBW): 33 pm (approx. 4.5 GHz) FWHM • Dynamic Range (OSNR): Greater than 35 dB • OSNR Measurement Uncertainty: ±0.5 dB • OSNR Repeatability: ±0.2 dB • Rejection Ratio: -35 dBc at 0.1 nm • Noise-Equivalent Bandwidth (NEB): Calibrated 1250 nm to 1650 nm • Input Power Handling: -10 dBm at 1550 nm Signal Analysis • In-Band OSNR Measurement: Up to 100 Gbit/s data signals; measurement time less than 6 seconds • Pol-Mux OSNR Measurement: Supports data signals up to 400 Gbit/s; 1 minute 20 seconds (all channels) or less than 5 seconds (single channel off) • Modulation Support: Any format including DP-QPSK and DP-BPSK • Channel Spacing: 12.5 GHz DWDM to CWDM ## Key Features • WDM Investigator: Signal and noise per-channel analysis with impairment detection (crosstalk, non-linear effects, carrier leakage, PMD pulse spreading) • DFB Laser Analysis: Characterization of central wavelength, peak power, bandwidth, and SMSR • Fabry-Perot Laser Analysis: Automatic characterization for central wavelength, RMS width, and FWHM • Spectral Transmittance: Insertion loss and channel isolation measurement at multiple power levels • Commissioning Assistant: Pol-Mux OSNR support with IEC-61282-12 and CCSA YD/T 2147-2010 compliance ## Typical Applications • DWDM and ROADM system characterization • Spectral component measurement and signal quality validation • Network commissioning and turn-up validation • In-band OSNR and Pol-Mux OSNR measurements • DFB and Fabry-Perot laser source qualification ## Compatibility & Integration The IQS-5240S/BP operates on the FTB-2 and FTB-2 Pro platforms, supporting both field and laboratory deployment scenarios.
