PRODUCT OVERVIEW

991940: NUT,SELF-LOCKING,HEXAGON.

Fiber optic cable carries information from one point to another in the form of light, and provides a vast array of features and benefits. Transmission Distance: It is not unusual for optical systems to go over 100 kilometers (km), or about 62 miles. Security: It is impossible to remotely detect a signal being transmitted within a fiber cable.

The only way to do so is by actually accessing the optical fiber itself. This makes fiber extremely attractive to governmental bodies, banks, and other businesses with major security concerns. No metallic components: Fiber optic cable can be installed in areas with electromagnetic interference (EMI).

This includes areas around utility lines, power-carrying lines, and railroad tracks. Fiber is also ideal for areas of high lightning-strike incidence. This part is cataloged in the U.S.

Government catalog under NSN 5310-01-554-5109, indicating validated use in U.S. government and defense logistics supply chains.
