Picking out Fiber Optic Cable

There are many different types of fiber optic cable.  FiberCables.com stocks hundreds of varieties and we can custom build thousands of other types. 

The sheer number of options can be overwhelming to people that don't work with fiber optic cable regularly.  So here are some common questions.

 fiber optics technician

Do you need singlemode or multimode fiber optic cable?

If you already have a cable and you need more of it, you can usually tell the type of cable by the color of it.  Single-mode cable is typically yellow.  Multi-mode cable (either 62.5 micron or 50 micron) is usually orange.  And 10GB multi-mode cable is usually aqua.

If you don't know the color, you have to find some sort of documentation that describes the type of cable you need.  Below are some terms and the type of cable they are usually associated with.

OS1, OS2, 9 micron, 9µm, 9/125 = Singlemode
OM1, 62.5 micron, 62.5µm, 62.5/125 = Multi-mode 62.5
OM2, 50 micron, 50µ, 50/125 = Multi-mode 50
OM3, 10GB, 10gig, 50 micron, 50µm, 50/125 = 10GB Multi-mode
As you can see, it can be a bit confusing since both 50 micron and 62.5 micron are multi-mode and are orange.  It's also confusing because 50 micron cable can also be 10GB aqua cable.  In cases where it isn't clear, you may have to find documentation for the hardware you are using to figure out what you really need.

Multimode special optical fibers


Multimode special optical fibers


Laser beam transmission with applications in manufacturing, medicine, spectroscopy, sensor technology and high-power laser transmission

Graded-index and step-index multimode fibers are used for data and power transmission. Undoped Fused Silica as a core material offers low attenuation and permits higher-power transmissions, e.g. from high-power lasers. Doped silica is used if a high numerical aperture is required for optimal launching of light into the fibers or to implement special fiber profiles.
google fiber technician salary

The size and shape (geometry) of the fiber core can be adjusted to match application requirements. With a suitable coating material and an optional buffer layer, the fibers can be protected from a wide range of environmental factors. All fibers can be adjusted, optimized, and assembled specifically for the customer’s individual application scenario along the entire value chain – from the initial manufacture of the Fused Silica starting material through to the final assembly.

We offer a broad portfolio of optical fibers that enables us to cover any wavelength range from ultraviolet through to near-infrared. You can select your fiber geometry from core sizes of 10 µm to 2.7 mm, and a wide range of circular and non-circular core/cladding fiber designs. Alongside multimode special optical fibers, we also make capillaries and tapers.

How Do Fiber Optic Cables Work?


Strands of glass are inside of fiber optic cables, which are very thin. The center of these strands is where the light travels.

 One optical fiber has enough strength to carry three million voice calls. Fiber optic cables also have a unique feature to help them prevent loss of signal and to operate efficiently.

This is known as cladding and is a layer of glass that helps to reflect light back in on itself. There are two main types of fiber optic cables functioning in a fiber optic network.

fiber optics technician

 These are known as single mode and multi-mode. Single-mode is known for thin glass strands, along with the use of a laser. Multi-mode is known for the use of LEDs.

ITU has developed some standardized fiber characteristics


 Other Elements of Fiber Cable Specifications
Various elements are often encountered n the nomenclature and specifications of fiber cables:

ITU has developed some standardized fiber characteristics like “G.651.1”; their mentioning implies that such specifications should be fulfilled.

Fiber Distributed Data Interface (FDDI) is a standard concerning LAN fiber cables, which however with its quite limited transmission speed of 100 Mbit/s has become obsolete due to the improved availability of advanced copper cables.
There can be additional classifications like OM1, OM2, OM3, OM4 and OM5 for graded-index fibers, which concern the residual level of intermodal dispersion. That limits the transmission bandwidth (or the bandwidth–distance product) of the cable.

 High performance is achieved e.g. with OM4 50/125-μm laser-optimized fibers, having a very precisely controlled refractive index profile.
Sometimes, the maximum achievable bandwidth–distance product is specified (in units of MHz·km).
Specs like “50/125 microns” indicate the core and cladding diameter. Large values of the core diameter – tens of microns – generally indicate multimode fibers.

3. Blocked cable failures are caused by compression “ripples” due to installation or improper preconditioning of optical cable.

When an optical cable is seated against the face of a connector, the face of the cable core and cladding will be pushed into the body of the cable by a very small amount, on the order of millimeters, at both ends.
fiber optic technician jobs
 Moreover, when an optical cable is subjected to thermal cycling, swinging back and forth between the extremes of its operating temperatures, this can cause the cable jacketing to shrink slightly. In both cases, the end result is an optical cable where the core and cladding has become compressed within the jacketing and is not free to move in a manner that would relieve the stress.  This increases light loss across the fiber and heightens the chance for what’s called a “blocked cable failure” (Fig.

These issues can be addressed via thermal preconditioning (cycling a pre-cut length of fiber multiple times between its anticipated operating temperatures to stabilize the jacketing shrinkage), the use of service loops, and limits placed on the restriction of fiber movement. Lastly, the use of an optical backscatter reflectometer can also return useful information about the internal structure of a fiber-optic cable, including very small compression-caused bends within the jacket.

Basic Elements of Modes Cable


Basic Elements of Modes Cable

There are three basic elements of a fiber optic cable

Core: Starting with the core, it is the area light transmission that occurs in the fiber, being either glass or plastic. With a large core, more light will be transmitted within the cable.
Cladding: It is used to provide a reflection within the core of the cable, this will help the light waves transmit through the fiber.
fiber optic cable technician salary
Coating: Like any other coating, it is used to be multi-layers on the cables to help preserve the strength of the fiber, as well as absorb shock and extra fiber protections needed.
The coats come in various amounts from 250 microns to 900 microns.

Through reading this article I hope it helped you have a better understanding of what fiber optics are and knowing the modes the cables come in, whether it is being single or multi-mode and each property that it holds in their mode.

As well as with the various colors from yellow, orange and so that is used to differentiate each mode of the cables

fiber optic cable detailing the core and cladding of the cable

“If you look very carefully in the middle, can you see a different sort of color?” Mazzali asked me. I looked and saw a very narrow, thin band of something-ness in nothing-ness. “That’s the core,” Mazzali said. “That’s where the light will be.”

Maurer’s team had decided that the way to make glass transmit light most effectively was, somewhat paradoxically, to make the core less pure than the cladding so that the latter would act as a mirror, trapping light inside the core. So chemicals were mixed into the core—through the tweaking of the soot layering—that did that. “You put a light in that core,” Mazzali said, “and it keeps reflecting back and forth.”
