Building upon the ARINC 801 terminus robust design, the Lightly™ terminus serves as the next iteration in usability for the existing design. By incorporating the ARINC 801 insertion and removal mechanism into the Lightly™ terminus body, users will no longer need to carry a separate tool into a production or maintenance area. This eliminates Foreign Object Debris (FOD) concerns while reducing rework and testing time. Utilizing the industry standard ARINC 801 terminus design as a baseline, the Lightly™ terminus excels in providing reliable and robust optical performance in the harshest of environments. The Lightly™ terminus can be installed with one hand into an ARINC 801 receptacle such as COTSWORKS’ RCP transceiver or a MIL/Aero Circular Connector. With a wide variety of options, the Lightly™ terminus product family supports the needs for any optical network.
