HP 83481A 20 GHz Electrical/3 GHz Optical Plug-In Module

The HP 83481A provides the ideal measurement system for testing single-mode SDH/SONET signals operating at 155 or 622 Mb/s as well as other high-speed telecommunications signals. The calibrated, integrated optical receiver, with over 2.5 GHz bandwidth, allows for easy, precise measurements of optical signals. An average power meter is built-in. For compliance testing, a hardware filter for both 155 Mb/s or 622 Mb/s testing can automatically be switched in to create a calibrated SDH/SONET reference receiver. The switchable filter minimizes setup time while maximizing measurement repeatability.
