Agilent 81624CE Electrical Extender Cable

The Agilent 81624CE is a 4-meter extension cable (“Electrical Extender Cable”) used with Agilent / Keysight optical measurement systems.

It’s an accessory of the 816xx family of lightwave / optical test equipment — specifically to extend the distance between optical heads / sensors and their interface/mainframe modules.

Connectors / interfaces are high-precision, since this is part of optical power / lightwave measurement systems. It’s designed to meet the performance requirements (signal fidelity, low interference, etc.) required in those setups.
