  • Everything You Need to Know About Fiber Optic Ethernet - In the last decade, a wide variety of applications have been developed that covers a dozen of datacom networking technologies. The transmission speed ranges from 10Mbits up to 10Gbit/s and growing. High distance-bandwidth product is the major selling point for fiber optic transceivers. Another major benefit of fiber optic systems is their high reliability compared to other media. Now fiber optic transceivers are commercially available for almost all international and industrial standards, including Ethernet, Fast Ethernet, Gigabit Ethernet, 10Gbit Ethernet. So let's review the the bunch of industry standards and inspect the various applications that fiber optic transceivers provide. There are two classifications for optical fiber: single-mode (SMF) and multi-mode (MMF).
  • Understanding the Fundamentals of Ethernet - Ethernet was developed at Xerox's Palo Alto Research Center (PARC) by Robert Metcalfe and David Boggs with Chuck Thacker and Butler Lampson in the early 1970s. Xerox filed a patent application for Ethernet in 1975. Today, Ethernet is based on IEEE standard 802.3 (Institute of Electrical and Electronic Engineers). Metcalfe left Xerox in 1979 and founded 3Com to promote local area networks and personal computers.
  • To get the best deal on a quality DS3 Line - When businesses consider upgrading their broadband connections to have more bandwidth, they often look for a DS3 line or an ethernet line. Because ethernet connections are only limited to certain areas, DS3 connections are usually the best options to consider. A DS3 and a T3 are the same kind of circuit, people use the words interchangeably.A T3 line is a super high-speed connection capable of transmitting data at a rate of 45 mbps (megabits per second) upload and download. A T3 connection represents a bandwidth equal to about 672 regular voice-grade telephone lines, which is wide enough to transmit full-motion, real-time video, and very large databases over a busy network.
  • Voip Systems - Just What Is An Ip, Anyway? - IP stands for "internet protocol" and references a data protocol that is used for communication across a network. A protocol, then, is a standard that governs the connection of that contact between two points on a network. Protocol also references a set of guidelines or rules that govern the aspects of the communication across the network. IP, then, is what is known as a network layer protocol and is housed and governed in a data linkage known as Ethernet. Ethernet refers to what are essentially a family of computer properties and technologies used across local area networks or LANs. Ethernet tends to provide unique global internet protocol addresses or IP addresses to users on the networks. IP is basically the tools of communication and the identity of a particular computer or network's "global address.
  • How To Choose Desktop PC - Desktops have become a very important device in today’s world. They are so very useful for one and all that it becomes very difficult for one to stay without.

  • Configure NAT Using Port Address Translation on a Cisco Router - Network Address Translation, better known simply as NAT, allows an outside address to represent a single or many inside addresses. There are several forms of NAT, but one of the most common is called NAT overloading, Port Address Translation, or simply PAT. PAT provides a many-to-one mapping with many inside private addresses mapped to one outside public address. We often see PAT used in home firewalls and routers to allow several home computers and perhaps a gaming console to use private addresses such as 192.168.1.
  • What Are Leased Lines? - There are many benefits of leased lines and below will explain and help make you understand these reasons. A leased line is a type of telecommunications line connecting two locations. It is also known as a dedicated line, a data line, or a private line. Unlike traditional telephony communication lines, it does not have a phone number connection, and therefore is always on 24/7 and available for each side to be connected together permanently.
  • Voice-Data Network Solution - What To Consider Besides Bandwidth And Cost - When you are deciding on a voice/data network solution for your business the obvious factors to take into consideration are bandwidth and cost. However if you base your entire solution on those factors alone you risk facing issues you could have easily prevented with just a bit more strategic thought and planning. The article "Why Do Businesses Prefer T1 And T3 Bandwidth Connections" is a good attempt at addressing the business issues involved with the decision making process for a small or medium business with limited telecommunications / network connectivity needs. But that is just a start. For businesses, with more than rudimentary network connectivity needs, there really is much much more involved in driving these kinds of decisions. Also, there are several more technology options beyond T1/T3 (aka DS1/DS3) and xDSL.

  • Bandwidth Ideal Solutions For Bandwidth Hungry Companies - Every business needs bandwidth solutions of some sort. For many businesses that require large amounts of bandwidth finding just the right solution....from a cost and application standpoint....can be a confusing process. It doesn't have to be if you understand what to base your decision on. Like anything in information technology, it really depends on how you will utilize this infrastructure. It certainly doesn't make sense to provision high capacity transport links if you will use them for a small fraction of the day or the traffic doesn't warrant it. I think one of the hardest things about this arena is that many times the people requesting the bandwidth are confused about what bandwidth really is. There's a misnomer that bandwidth automatically equals speed.

  • What Fiber Optic Supplies Do You Need To Clean A Fiber Optic Connector? - First, let’s understand why a fiber optic connector needs cleaning. You may never need to clean the RJ45 connector for your computer’s Ethernet network connection, then why do you need to clean a fiber optic connector if it serves the same purpose as a networking connection? While, the answer lies in how optics work differently than electronics. In electronics, as long as you have a contact between two connectors, they work perfectly; or at least most of the time. But for optics, light beams travel in straight lines, they bounce off whenever they hit anything and thus loss their energy. So in order for a light beam to carry the information signal and travel thousands of miles of optical fiber, its path must be kept crystal clear, including fiber optic connectors in the network.
  • What Is Structured Cabling For Computer LAN Networks? - :: What is structured cabling? Modern computer LAN (local area network) wiring has the concept of structured cabling.
