The EXFO PPM-350B is a single-wavelength (1310 nm) optical power meter engineered for upstream burst signal measurement in Passive Optical Networks. This handheld instrument delivers accurate power readings for both continuous and burst-mode signals encountered in FTTH and FTTP deployments. The meter features pass/warning/fail indicators, configurable threshold sets, and optional extended-range capability for central office testing. Available in one-port and two-port pass-through configurations, it enables field technicians to rapidly assess signal integrity across BPON, EPON, and GPON architectures operating at 155 Mb/s through 2.5 Gb/s.
