Difference Between AON and PON

AON (Active Optical Networks) and PON (Passive Optical Network) serve as the two main methods of building CWDM and DWDM backbone network. Each of them has their own merits and demerits. This article will compare them according to their different features and applications.

AON

An active optical system uses electrically powered switching equipment, such as a router or a...

Necessary Components in DWDM Systems

DWDM (Dense Wavelength Division Multiplexing) is used to increase the amount of information or systems that can be transmitted over a single fiber, thus allowing allow for more channels with much tighter channel spacing. In DWDM systems, DWDM devices combine the output from several optical transmitters for transmission across a single optical fiber. At the receiving end, another...

Passive DWDM vs. Active DWDM

To keep pace with the rapidly growing volumes of data-network traffic driven by the growth of the Internet, service providers are always looking to increase the fiber capacity and wavelength spectral efficiency in their networks. DWDW (dense wavelength division multiplexing) is an optical multiplexing technology used to increase bandwidth over existing fiber networks. DWDM works...

Evolution of Optical Wavelength Bands

As fiber optic networks have developed for higher speeds, longer distances, and wavelength-division multiplexing (WDM), fibers have been used in new wavelength ranges, namely "bands". Fiber transmission bands have been defined and standardized, from the original O-band to the U/XL-bands. This article will mainly illustrate the evolution of the typical fiber transmission bands ...

Installation Guide for RJ45 Modular Jack on CAT5e Shielded Cable

RJ45 modular jack is used for mounting optical connectors into the wall plate or patch panel for network wiring installs. There are numerous requests for wiring diagrams or general information on how to punch down or terminate keystone jacks (Cat5e / Cat6) after running your telecom network's cross-connect cabling. Building a patch cable involves installing RJ45 plug connectors...

Shielded vs. Unshielded Twisted-Pair Cable

As we all know, the advantages and disadvantages of shielded and unshielded twisted-pair cable are under debate for a long time. Advocates of STP cable, which includes screened twisted-pair and foil twisted-pair cables, claim that it is superior to UTP cable. Shielded versus unshielded twisted-pair cable, which is the winner? This post will give you the answer.

STP and UTP...

Demystifying Twisted-Pair Cable Connector Types

Have you ever wired a cable directly into a piece of hardware? Some equipment in the past years provided terminals or termination blocks so that cable could be wired directly into a direct component. At the ends of the cables you install, something must provide access and transition for attachment to system electronics. Thus, you need connectors.

Connectors usually have a male...

Demystifying Ethernet Category Types

Ethernet represents the plumbing pipes of the Internet. Many network installers are familiar with Cat5e and Cat6 cables with RJ45 connectors. But the term “Ethernet”, co-invented by Robert Metcalfe, encompasses an entire range of twisted pair and fiber cables that are constantly being upgraded and standardized by the Institute of Electrical and Electronics Engineers known as...

Introduction to Cat6 Ethernet Cables

The Emergence of Cat6 Cable

Category 6 (CAT6) is an Ethernet cable standard defined by the Electronic Industries Association and Telecommunications Industry Association (commonly known as EIA/TIA). CAT6 is the sixth generation of twisted pair Ethernet cabling. Cat6 increases the bandwidth of the Cat5/5e from 100MHz to 250 MHz and allows for better signal to noise ratio with...
