LXI Optical Switching - 16x16 Matrix Plugin Module
65-280-314
Matrix Switch Module
The 65-280-314 16x16 matrix is part of the 65-280 and 65-281 ranges of optical plug-in modules offering matrix & insert/bypass or multiplexer & SPST topologies respectively with all models based on MEMS fiber optic switches and available in various populations per plugin. In addition, a choice of different connector styles to suit most applications is offered: FC/APC (for optimal performance), FC/PC, SC/PC and ST for general applications and LC for high density applications. They use MEMS (Micro-Electro-Mechanical-Systems) based optical switches to route signals between terminals by redirecting the optical signal. This is achieved using micromechanical mirrors driven by a highly precise mechanism activated via an electrical control signal.

PXI Relay Module
Relay
PXI Relay Modules consist of multiple independent relays, such as single-pole single-throw (SPST), single-pole double-throw (SPDT), and double-pole double-throw (DPDT) relays. PXI Relay Modules use a variety of relay types, including electromechanical armature relays, reed relays, field-effect transistor (FET) relays, and solid-state relays, each with their own benefits, allowing you to choose a set of relays that fit your requirements. To program the relays, you can use the IVI-compliant NI-SWITCH driver software, complete with help documentation, example programs, and a soft front panel application for interactive control. For intelligent management of complex switch systems, NI Switch Executive provides additional software tools to help you design, build, and deploy your switching system.
