Agilent/Keysight E1662A

The Agilent/Keysight E1662A is a C-size VXI optical interface module engineered for SONET/SDH (Synchronous Optical Networking/Synchronous Digital Hierarchy) testing at 155.622 Mb/s. This module integrates into standard VXI instrumentation chassis to enable characterization and testing of optical line interfaces in telecommunications and networking environments. The E1662A operates as a discrete measurement component within larger VXI-based test systems, pairing with external optical connectors and complementary modules for complete protocol validation.
