Zygo Daisy Chain Cable

The Zygo Daisy Chain Cable is a fiber optic interconnect designed to daisy-chain reference signals across ZMI 2400 and 4000 series Measurement Boards. It enables creation of extended measurement networks while maintaining signal integrity and simplifying system integration. The cable features male ST bayonet connectors at both ends and a 400 micron core optimized for reliable optical transmission in multi-board configurations.
