The FTBx-5255 from EXFO Inc. is an Optical Spectrum Analyzer that can measure wavelengths from 1250 to 1650 nm. It has a resolution bandwidth of 0.035 nm and up to 0.02 nm for high-resolution mode with a dynamic range of -80 to 18 dBm. This spectrum analyzer has wavelength linearity of ±0.01 nm and wavelength repeatability of ±0.003 nm. It has an optical return loss of over 40 dB and an optical rejection ratio of 45 - 55 dB.
The FTBx-5255 has a Robust In-service Pol-Mux OSNR for 100G/200G/400G. It provides a portable solution for spectral characterization of DWDM/CWDM networks. This spectrum analyzer can be combined with the FTBx-88200NGE Power Blazer module to become the industry’s smallest OSA/transport solution in a single platform for commissioning 40G/400G circuits. It can be housed in the compact and portable FTB-2, FTB-2 Pro, and FTB-4 Pro platforms, or in the rack-mountable LTB-8 platform that measures 51 x 159 x 185 mm and is ideal for high-speed, CWDM, O, and L-Band testing applications.
