Verify thread pitch — metric != imperial
PRODUCT OVERVIEW

Information carried in the form of light provides a vast array of features and benefits. _x000D_<br>_x000D_<br>Superior Transmission Distance_x000D_<br>It is not unusual for optical systems to go over 100 kilometres (km), or about 62 miles. _x000D_<br>_x000D_<br>Enhanced Security_x000D_<br>It is impossible to remotely detect a signal being transmitted within a fibre cable.

The only way to do so is by actually accessing the optical fibre itself. This makes fibre extremely attractive to governmental bodies, banks and other businesses with major security concerns._x000D_<br>_x000D_<br>No Metallic Components_x000D_<br>Fibre optic cable can be installed in areas with electromagnetic interference (EMI). This includes areas around utility lines, power-carrying lines and railroad tracks.

Fibre is also ideal for areas of high lightning-strike incidence. This part is cataloged in the Federal Logistics Information System (FLIS) under NSN 5325-00-200-5234, indicating validated use in U.S. government and defense logistics supply chains.
