What connectors do you need?





What connectors do you need?

There are many types of connectors for fiber cable.  The most common connectors for our customers are:
fiber optic jobs near me


 Connector Photo Description
FC This is a single (simplex) FC connector.
LC This is two (duplex) LC connectors held together by a clip.
SC This is two (duplex) SC connectors held together by a clip.
ST This is a single (simplex) ST connector.


There are many other types of cable available.  We custom build almost any cable you need.



What is Return Loss?

When light hits the end of a fiber optic cable, a portion of it can bounce back towards the source.  This is known as Back Reflection and it can cause a few different problems.  Return Loss is the term for how much the end of a cable cuts down on Back Reflection.

You want as much Return Loss as possible.

Fiber Optic Cable is available in many different constructions

Fiber Optic Cable
Fiber Optic Cable is available in many different constructions to satisfy the needs of a wide range of types of applications. A fiber optic cable is composed of at least one fiber and can be up to 6,912 strands of optical fiber. Each of the optical fibers is smaller in diameter than a human hair. For high density applications,

Micro Distribution Cable is ideal because it can provide a high fiber count in a small footprint. Simplex and Duplex cables are perfect for fiber optic patch cables. Loose tube optical cable is the way to go for outdoor installations especially in direct burial applications. No matter what type of bulk fiber optic cable your installation needs, we can help.

he wasn’t going to be any more specific


He pointed up again: “Can you see there, the gob going down?” A big blob, glowing white, was hanging off the end of an enormous clear glass tube. That one tube, he said, would produce a few thousand kilometers of glass strand. He smiled; he wasn’t going to be any more specific. “This is the top of the draw,” he said. “We’re going to go down a few floors.”

We ran down the stairs, with me clattering after Mazzali. He opened the door on the floor just below where we had been and pointed ahead of us: “Can you see the fiber?” he asked. “No,” I said. “Look carefully,” he said. And there it was, an impossibly thin strand, descending from a big hole in the ceiling to the floor. “Now you’re going to see the last stage, which is putting it on a spool,” he said.
cable installer certifications
We clattered down more stairs into the basement. There a calm, tall man named Matt was watching gauges as the strand of fiber wound onto a spool. He was looking for imperfections. “Remember that the fiber is 125 microns in diameter, plus or minus less than a micron,” Mazzali said.
“We have to control the diameter of this glass, every single meter of it, over more than a thousand kilometers, by all of this equipment that we have on the draw, the tension, the temperature, the speed, and all that,” so that whenever a splice has to be made—a connection between one strand of fiber-optic cable and another—the fiber will transmit perfectly.
