Duplex Fiber Cable

Duplex fiber cable is designed for general fiber patch cord production where consistency and uniformity are vital for fast, efficient terminations. We have the right duplex fiber cable in many different outside diameter (OD) sizes and meet all tooling and termination requirements.Duplex Fiber Optic Cables consist of two fibers joined by a thin connection between the two jackets. Workstations, fiber switches and servers, fiber optic modems, and similar hardware require duplex cable. They are used in applications where data needs to be transferred bi-directionally. One fiber transmits data one direction; the other fiber transmits data in the opposite direction. Duplex fiber optic cables from FiberStore can be available in single-mode and multimode.

Multimode vs Singlemode Fiber

A “mode” in Fiber Optic cable refers to the path in which light travels. Multimode cables have a larger core diameter than that of singlemode cables. This larger core diameter allows multiple pathways and several wavelengths of light to be transmitted. Singlemode Duplex cables and Singlemode Simplex cables have a smaller core diameter and only allow a single wavelength and pathway for light to travel. Multimode fiber is commonly used in patch cable applications such as fiber to the desktop or patch panel to equipment. Multimode fiber is available in two sizes, 50 micron and 62.5 micron. Singlemode fiber is typically used in network connections over long lengths and is available in a core diameter of 9 microns (8.3 microns to be exact). Many types of multimode fiber optic cable (such as om3 multimode fiber) and singlemode fiber optic cable for sale in FiberStore.

How Fiber Optic Cables Work

The traditional method of data transmission over copper cables is accomplished by transmitting electrons over a copper conductor. Fiber Optic cables transmit a digital signal via pulses of light through a very thin strand of glass. Fiber strands (the core of the fiber optic cable) are extremely thin, no thicker than a human hair. The core is surrounded by a cladding which reflects the light back into the core and eliminates light from escaping the cable.

A fiber optic chain works in the following manner. At the one end, the fiber cable is connected to a transmitter. The transmitter converts electronic pulses into light pulses and sends the optical signal through the fiber cable. At the other end, the fiber cable is plugged into a receiver which decodes the optical signal back into digital pulses.

Advantages & Disadvantages of Fiber Optic Cable

There are many advantages and disadvantages in using fiber optic cable instead of copper cable. One advantage is that fiber cables support longer cable runs than copper. In addition, data is transmitted at greater speeds and higher bandwidths than over copper cables.
The major disadvantages of fiber optic cables are cost and durability. Fiber cables are more expensive than copper cables and much more delicate.

Three Steps To Pick Out A Fiber Optic Cable
So when you go to pick out a fiber optic cable, there are a few things you’ll want to know. First, make sure that the type of connector you purchase matches your input connection. Second, check to see if your device prefers single or multi-mode transfer. Figure out if you need simplex fiber optic cable or duplex fiber optic cable. And finally, choose which length you need. You can discern this by setting up your system and running a string from the speaker or TV to the equipment. Always buy the next larger length rather than one that is on the small side. You won’t regret it!
