Agilent Technologies Inc.'s new optical switches enable more cost-effective optical transceiver manufacturing tests and higher efficiency in optical component and cable verification. The N7731A dual 1 x 4 and the N7734A 1 x 13 optical switches are available for single- or multimode fiber optic connections. They make accurate measurements and render automation easier with fast switching time and flexible control with LAN, USB 2.0 and GPIB (general-purpose interface bus) connections. Features and specifications include repeatability of ±0.01 dB, with ±0.004 dB typical; switching time of <20 ms; lifetime of >1 billion cycles; 816 x VXI plug-and-play driver support; and an N77xx GUI (graphical user interface). The N77 series instruments are built on a common platform and provide a common PC-based user interface.
