The WG OSA 155 DWDM Analyzer is a portable optical spectrum analyzer engineered for field testing and monitoring of Dense Wavelength Division Multiplexing systems. It delivers precise measurements of wavelength, optical signal power, and OSNR across the 1450 nm to 1650 nm band, accommodating high-channel-count DWDM networks with channel spacings of 50 GHz / 0.4 nm and above. The instrument features a 10.4-inch TFT touchscreen display, multiple operating modes for spectrum analysis and WDM tabular readout, and flexible power options including rechargeable internal battery, external DC input, and AC mains. Its interchangeable optical connector system supports SC/PC and FC/PC interfaces, while optional monitor output enables integration with external SDH/SONET analyzers. Field-proven rugged construction and remote operation via modem or LAN (TCP/IP) make the WG OSA 155 suitable for field operations and network operations centers alike.
