Ethernet on copper ... should as part of its network architecture or not? Discover the pros and cons before making an investment decision. Otherwise you run the risk of a costly mistake.
The only PRO Ethernet over copper (EOC) you definitely get immediate cost savings and, perhaps, to upgrade an early implementation of the restrictions with the vulnerability to external influences (aging, copper cable plant and the distance from the CO) and the ' interference.

Core / backboneLinks I think fiber is a must in many cases, as it gives you the ability to easily scale to higher bandwidth and different technologies (MPLS, CWDM, etc.) on the same fiber. The distance constraints are at least 100 times that of the EOC, in most cases (depending on the interconnect technology) The only cost to implement here, but the ROI for the next year as it would be worth it.
EOC has its place as the last mile for you, from the floor distributor to the servers,Work, etc., where the distance is much less of a problem, and in many cases, the interference can be limited by SOP correct wiring.
I had a chance to see it from the perspective of service providers and there is hardly a problem with a fiber connection in addition to fixing the hardware failure and even this is rare.
Thus, the maintenance cost of the fiber is usually not available to provide small, while for the EOC to perform routine maintenance, expected QoS, or even basicService in some situations.
No Doubt copper technology is inexpensive compared to a short optical fiber. But given the long distance optical fiber is the best solution in terms of maintenance and losses that occur in various electric vehicle.
Copper wires are very prone to various ailments. One that is in the worst case of EMP impacts on electric media such as copper wires. With a flash of electromagnetic radiation from an explosion orsuddenly fluctuating magnetic field .... The resulting electric and magnetic fields can produce torque with electrical / electronic systems to prevent damage from power surges and voltage. This is likely to damage electronic equipment and electrical infrastructure.
So, above all, the most important applications or areas should be critical of these effects. It should be stipulated in the design of an organization's network. This should be your electical wiresIt also comes from outside the organization. To eliminate the effects of EMP on power lines must be isolated EMP to depend on the ability of filter devices in standby mode.
Let me throw a little 'more esoteric differences.
* Copper interfaces and modules are more frequent and possibly economic.
Copper interfaces * usually at the expense of increased over-subscription rates for the next ASIC compared to the fiber, first the port density on the modules orCards.
* The physical separation between copper and fiber plant investment is often desirable to distinguish between client / server and network infrastructure services. Often, separate tracks are (or should be) used.
* The higher bandwidth of fiber technologies available before making copper.
In addition to drastically cheaper (multimode fiber can double the cost of a job), copper is the only realistic to implement Power over Ethernet, thecan also realize savings in several ways.
The fiber is ideal for backbone, it is convenient. Ultimately, if the company needs more than the cost of fiber then go with fiberglass. The same applies to the free space, even if the costs associated with the free space than the equipment used.
I want 10/100/1000 copper and answer questions about the bandwidth EM interference occurs by default, and users with motility, such as fiber and RF cases. A good example is in applications where fiberCable passing cars, as in a CAD / CAM / JIT shop. Jobs come and be in the hopper, which is passed to a machine next to a large lathe. Even the energy distribution of the fibers you within a certain distance from the turbines.
A solid understanding of the fundamentals of basic technique does not lead you wrong. And on the question of removal of copper is always possible to install low-power ARM micro-servers such as routers and repeaters, which are from the power supply is configuredEthernet cable.
Basically, it all depends on family size. Especially in terms of local network .... where the possibilities are wireless or wired.
The fiber is the ideal choice if your budget can help to increase due to the low cost of bandwidth in the future. With glass, you pay in advance for future expansion.
Let us now focus on WiFi / WiMax see EOC.
1 You have a competent staff to support access points, intrusionDetection and prevention of security and wireless in general?
2 Do you have an existing infrastructure EOC? Old as capable?
3 Most buildings on campus? Hybrid cars are no longer here. A combination of glass, copper and wireless.
In short, the answer is "it depends".
If I had an existing system with patch panels and switches, I would like to keep it running as long as possible. Not every PC needs access to Gigabit Ethernet.
I would, however, redundantFiber rings connecting each closet and data centers.
