Fiber Optic Cable Construction

Communication-grade optical fibers are manufactured from fused silica (SiO2) glass of exceptional purity. A single strand of optical fiber made

An optical fiber is a “pipe” through which light flows. This is, of course, merely an analogy for how an

Electronic signals used in traditional instrumentation circuits are either DC or low-frequency AC in nature. Measurement and control values are

Magnetic fields, unlike electric fields, are exceedingly difficult to completely shield. Magnetic flux lines do not terminate, but rather loop.

The fundamental principle invoked in shielding signal conductor(s) from external electric fields is that no substantial electric field can exist

If sets of wires lie too close to one another, electrical signals may “couple” from one wire (or set of

In the interest of safety and longevity, one cannot simply route electrical power and signal cables randomly between diﬀerent locations.

DIN stands for “Deutsches Institut fur Normung”, which means “German Institute for Standardization.” In the 1970’s the name DIN became the

There is much to be said for neatness of assembly in electrical signal wiring. Even though the electrons don’t “care”

Tube bending is something of an art, especially when done with stainless steel tubing. It is truly magniﬁcent to see
