Exfo FTB-5230 1250nm Portable Optical Spectrum Analyzer

The EXFO FTB-5230 is a portable optical spectrum analyzer (OSA) module designed for field testing of CWDM and DWDM systems across metro, access, and long-haul network deployments. Operating within the EXFO FTB-400 Universal Test System platform, this cost-effective analyzer delivers essential OSA functionality for network commissioning, installation, management, and troubleshooting. The FTB-5230 spans 1250 nm to 1650 nm with wavelength resolution of 100.0 pm and peak FWHM linewidth ≤ 0.1 nm, enabling characterization of channel spacing down to 50 GHz. Wavelength uncertainty is ± 0.1 nm. Dynamic range extends from 10 dBm to –60 dBm with power uncertainty of ± 0.4 dB. Optical rejection reaches 55 dBc typically at 50 GHz (± 0.4 nm), 45 dBc at 100 GHz (± 0.8 nm), and up to 50 dBc at 0.2 nm spacing. PDL measures ± 0.1 dB typically at 1550 nm. Scanning time is 4 seconds across a 35 nm span for multiple-peak analysis. Optical return loss exceeds 35 dB. ## Technical Specifications • Wavelength range: 1250 nm to 1650 nm • Wavelength resolution: 100.0 pm; ≤ 0.1 nm FWHM • Wavelength uncertainty: ± 0.1 nm • Channel spacing characterization: down to 50 GHz • Dynamic range: 10 dBm to –60 dBm • Power uncertainty: ± 0.4 dB • Optical rejection ratio: 55 dBc @ 50 GHz, 45 dBc @ 100 GHz, up to 50 dBc @ 0.2 nm • PDL @ 1550 nm: ± 0.1 dB typical • Scan time: 4 seconds (35 nm span) • Optical return loss: > 35 dB • Maximum safe input power: 29 dBm • Operating temperature: 0 to 40 °C • Module dimensions: 96 mm (H) × 76 mm (W) × 26 mm (D) • Module weight: 2.2 kg ## Key Features • Drift mode for wavelength and power monitoring over time, critical for uncooled laser systems • WDM and Optical Channel Analyzer (OCA) analysis modes • CWDM/DWDM optimization with support for 33 to 200 GHz channel spacing • Integrated within portable FTB-400 platform for multi-module field deployment ## Typical Applications • Network commissioning and installation • Wavelength and power stability verification • ITU-T G.694.2 and G.695 compliant system testing • Metro and long-haul CWDM/DWDM characterization ## Compatibility & Integration The FTB-5230 operates as a module within EXFO FTB-400, FTB-2, FTB-2 Pro, and FTB-500 platforms.
