Fiber Optic Network. Fiber Optic Networks.

In the telcos, singlemode fiber is used to connect long distance switches, central offices and SLCs (subscriber loop carriers, small switches in pedestals in subdivisions or office parks or in the basement of a larger building). Practically every telco's network is now fiber optics except the connection to the home. Fiber to the home is not yet cost effective - especially since most homes do not want (nor are willing to pay) for the high speed services that would justify fiber optics. They lash fiber cable onto the aerial . The fiber allows them to break their network into smaller service areas that prevent large numbers of customers from being affected in an outage, making for better service and customer relations.

The fiber also gives them a return path which they use for Internet and telephone connections, increasing their revenue potential. The LAN backbone often needs longer distance than copper cable (Cat 5/5e/6) can provide and of course, the fiber offers higher bandwidth for future expansion.

Most large corporate LANs use fiber backbones with copper wire to the desktop. Fiber to the desk can be cost effective if properly designed. CCTV is often on fiber for it's distance capability. Microsoft Office 2007 Mathematical Symbols And Their Meaning. Industrial plants use lots of fiber or distance and noise immunity. Utilities use it for network management, liking its immunity to noise also. The military uses it because it's hard to tap or jam. Airplanes use it for that reason too, but also like the lighter weight of fiber.

Designing Cable Networks. I guess this is too big a topic for a overview! But we'll pass along some hints to make life easier. First and foremost, visit the work site and check it out thoroughly. Don't cut corners which may affect performance or reliability. Consider what are the possible problems and work around or prevent them. There ain't no substitute for common sense here!

Preparing this cable includes. Mohawk is a manufacturer of copper, fiber, broadcast cable products. We support an open architecture philosophy and offer an open solution to cabling.

For example, you can install all the electronics for a network in one communications closet for a building and run straight to the desktop with fiber. With copper, you can only go about 9.

With fiber, you only need passive patch panels locally to allow for moves. Upgrades are easy, since the fiber is only loafing at today's network speed! Is Copper Really Cheaper Than Fiber? When it comes to costs, fiber optics is always assumed to be much more expensive than copper cabling. Whatever you look at - cable, terminations or networking electronics - fiber costs more, although as copper gets faster (e.

Cat 6) it gets more expensive, almost as much as fiber. So isn't it obvious that fiber networks are more expensive than copper? There is more to consider in making the decision. Why Use Fiber? If fiber is more expensive, why have all the telephone networks been converted to fiber? And why are all the CATV systems converting to fiber too? Are their networks that different? Is there something they know we don't?

Telcos use fiber to connect all their central offices and long distance switches because it has thousands of times the bandwidth of copper wire and can carry signals hundreds of times further before needing a repeater. The CATV companies use fiber because it give them greater reliability and the opportunity to offer new services, like phone service and Internet connections. Both telcos and CATV operators use fiber for economic reasons, but their cost justification requires adopting new network architectures to take advantage of fiber's strengths. A properly designed premises cabling network can also be less expensive when done in fiber instead of copper. There are several good examples of fiber being less expensive, so lets examine them. Industrial Networks.

In an industrial environment, electromagnetic interference (EMI) is often a big problem. Motors, relays, welders and other industrial equipment generate a tremendous amount of electrical noise that can cause major problems with copper cabling, especially unshielded cable like Cat 5. In order to run copper cable in an industrial environment, it is often necessary to pull it through conduit to provide adequate shielding.

With fiber optics, you have complete immunity to EMI. You only need to choose a cable type that is rugged enough for the installation, with breakout cable being a good choice for it's heavy- duty construction.

The fiber optic cable can be installed easily from point to point, passing right next to major sources of EMI with no effect. Conversion from copper networks is easy with media converters, gadgets that convert most types of systems to fiber optics. Even with the cost of the media converters, the fiber optic network will be less than copper run in conduit.

Long Cable Runs. Most networks are designed around structured cabling installed per EIA/TIA 5. This standard calls for 9.

UTP) cable and 1. But suppose you need to connect two buildings or more? The distance often exceeds the 9.

By the time you buy special aerial or underground waterproof copper cable and repeaters, you will usually spend more than if you bought some outside plant fiber optic cable and a couple of inexpensive media converters. It's guaranteed cheaper if you go more than two links (1. Centralized Fiber LANs. When most contractors and end users look at fiber optics versus Cat 5e cabling for a LAN, they compare the same old copper LAN with fiber directly replacing the copper links. The fiber optic cable is a bit more expensive than Cat 5e and terminations are a little more too, but the big difference is the electronics which are $2. However, the real difference comes if you use a centralized fiber optic network - shown on the right of the diagram above. Since fiber does not have the 9.

UTP cable, you can place all electronics in one location in or near the computer room. The telecom closet is only used for passive connection of backbone fiber optic cables, so no power, UPS, ground or air conditioning is needed. These auxiliary services, necessary with Cat 5 hubs, cost a tremendous amount of money in each closet. In addition, having all the fiber optic hubs in one location means better utilization of the hardware, with fewer unused ports.

Since ports in modular hubs must be added in modules of 8 or 1. With a centralized fiber system, you can add modules more efficiently as you are supporting many more desktop locations but need never have more than a one module with open ports. High Speed Networking. It was over a year after Gigabit Ethernet (Gb. E) became available on fiber optics that it finally become available on Cat 5e. It took another couple of years before Gb. E on copper became significantly less expensive.

In order to get Gb. E to work over Cat 5e, the electronics must be very complicated, and consequently as expensive as fiber.

A newer version is in the wings, awaiting a Cat 6 standard, but that means the version running over Cat 5e will be obsolete before it even gets started! Finally, we went to a major distributor's seminar on advanced cabling recently and the copper marketing guy told us to go fiber for Gb. E. Bottom Line. So when it comes to costs, looking at the cabling component costs may not be a good way to analyze total network costs. Consider the total system and you may find fiber looks a lot more attractive. Pre- Terminated Fiber.

Pre- terminated fiber optic cable assemblies are gaining steam as organizations begin to favor the ease of use provided by factory termination. Instead of purchasing raw fiber and necessary equipment and having to cut, terminate and test it in the field, organizations can use pre- terminated fiber assemblies to purchase exactly what they need and roll the new network cabling system out quickly. Pre- terminated fiber is a plug and play solution with factory tested and polished connectors ready for immediate installation. At LANshack, we make Pre- Terminated fiber custom in the USA to your exact specifications. Any variety of fiber, connector type, or lenght we can make.

If you don't see what you need ask us and we'll see if we can make it!
