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.
