Indoor/Outdoor Multifiber Cables

by Fiber-MART.COM In the case of building network connectivity between two buildings, within a large building, or connecting networks from the cabinet of the third-party Internet service provider (ISP) to your home, fiber optic cable is used in order to meet the requirements of bandwidth, distance and noise. Outdoor fiber [ Continue reading…]

What’s optical network (photonic network)

An optical (photonic) network is a communications network in which information is transmitted as optical or infrared radiation transmission (IR) signals.      In a true photonic network, every switch and every repeater works with IR or visible-light energy and conversion to and from electrical impulses is only done at [ Continue reading…]

What’s fiber to the x (FTTx)

Fiber to the x (FTTx) is a collective term for various optical fiber delivery topologies that are categorized according to where the fiber terminates.   Optical fiber is already used for long-distance parts of the network, but metal cabling has traditionally been used for the stretches from the telecom facilities to [ Continue reading…]

fiber optics (optical fiber)

Fiber optics, or optical fiber, refers to the medium and the technology associated with the transmission of information as light pulses along a glass or plastic strand or fiber. A fiber optic cable can contain a varying number of these glass fibers — from a few up to a couple [ Continue reading…]

Multimode Fiber Optic Cable

Today, multimode fiber optic systems are lagging behind singlemode systems in terms of growth. In addition to supporting high data throughput, singlemode systems are attractive because they are easy to upgrade and help to “future proof” installations.  Nonetheless, multimode fiber still gets plenty of coverage in any fiber optic cable guide.  Why? [ Continue reading…]

What is Fiber Optic Cable?

The world of telecommunications is rapidly moving from copper wire networks to fiber optics. Optical fiber is a very thin strand of pure glass which acts as a waveguide for light over long distances. It uses a principle known as total internal reflection. Fiber optic cable is actually composed of two layers [ Continue reading…]

7 Advantages of Fiber Optic Cables Over Copper Cables

When you’re planning a new network cable installation or considering upgrades to an existing network, you might want to consider using fiber optic cables.   Network fiber cables have some definite advantages over copper cables.   Copper cables were originally designed for voice transmission and have a limited bandwidth. Fiber optic [ Continue reading…]

What is DWDM and Why is it Important?

It has been almost 20 years since DWDM came on the scene with Ciena’s introduction of a 16 channel system in March of 1996, and in the last two decades it has revolutionized the transmission of information over long distances.  DWDM is so ubiquitous that we often forget that there was a time [ Continue reading…]

dense wavelength division multiplexing (DWDM)

DEFINITION dense wavelength division multiplexing (DWDM)   Dense wavelength division multiplexing (DWDM) is a technology that puts data from different sources together on an optical fiber, with each signal carried at the same time on its own separate light wavelength. Using DWDM, up to 80 (and theoretically more) separate wavelengths [ Continue reading…]
