The Keysight N773-C family of single-mode fiber-optic switches are an indispensable tool to automate photonic test solutions. Based on optical micro-electro-mechanic systems (MEMS) technology, those switches use tiny mirrors to guide the light to the desired output. MEMS based optical switches offer outstanding durability, repeatability, and fast switching times. Optical switches help avoid uncertainties introduced by fiber movement or by connector wear, and offer higher repeatability than manual re-connecting.
The new switch generation sports an on-board graphical user interface for easy control without software installation, accessible via GbE LAN and USB 2.0 connections. It comes in three topologies covering typical applications requiring 1x4 or 1x16 or 2x2 configurations.
The N7731C offers two independent 1x4 switches, ideal to connect up to four devices to stimulus (source) and response (detector) instruments, or to share up to four measurement instruments with the same device under test.
