Precision Fiber Optic

Would an i7 chip be faster than my Xeon chip?

I'm not sure what kind of a chip a Xeon is but I have a Dell Precision with a Xeon chip that's running on Windows XP. It's fairly fast and still satisfied with it. It's a business computer but I use it for home use.

Would a new Dell computer running on i7 chip with Windows 7 be any faster?

I have 4GB RAM on my current computer and if I get a new one I'll probably have 8GB.

I have high speed fiber-optic internet so internet speed is not an issue.

Would it make any difference to upgrade now or wait?

I mostly surf the internet, download movies, e-mail, shopping, and do most of my personal business transactions with my computer.

Thanks.

you're right, the precision is a PROFESSIONAL BUSINESS class computer with EXTREME reliability as it's main design objective. Without telling us model numbers, there is no way to tell how old it is, or what it's relative power is. If it's running XP, it is a VERY old system, but will probably last several more years (but you should always keep it backed up). The trouble is you cannot be absolutely sure, when it will go, or what part would go. If your business relies on it, I'd start looking for the replacement now. It never hurts to have a new computer, but:

You do NOT need i7 for MOST business uses. You can save money on the chip, and spend more on the "class" of the computer or to get a second computer for PERSONAL use.

More recent computers MIGHT have faster RPM drives, but MIGHT OR MIGHT NOT have the same reliability of the server class hard drives in your old system.

I would get a cheaper inspiron, studio, xps (if you want to stick with dell) or an asus, toshiba, compaq for HOME or personal use and keep the business machine ONLY for business. I would use an optiplex, latitude or precision for the business. There is no substitute for dell for pro workstations.

BASED ON YOUR CLAIMED USAGE, it will not be substantively faster. NOTHING you are doing now is very CPU or HD intensive.
If you are juggling large databases, a new core i3, i5 or i7 would be better. Remember, If you're running your system as a server, you can configure your new dell with a modern 4 or 6 core xeon processor too ! You can get PRO class hard drives.

If you buy a consumer level computer, computer, even a dell, it will be less reliable than your current precision workstation, even considering your current computer is like 8 years old. If you upgrade to another computer stay with a business class computer for your company. IF youbuy a consumer class computer it will not have pro class hard drives nor "bulletproof" motherboards.

You should NEVER download movies or music on a company computer. Do you think the IRS, your accountant, the people that owe you money, the people you owe money are going to care if you get a virus?

The Secrets of Choosing Ribbon Fiber

Do you know why it is so expensive to install Fiber To The Home? Why Bell companies are reluctant to deploy fiber optic network directly to consumers in a large scale?

It's not the material cost. It's the labor! The introduction of fiber into the subscriber loop has increased the installation of short cable lengths with large number of splices. The speed at which the cables can be placed, spliced, accessed and reconfigured are becoming extremely important.

So the need for new technologies that promise to reduce the fiber deployment cost are very high. Bell companies are anxious on acquiring these new technologies and products in order to reduce their cost and push the broadband fiber optic network installation.

That is where the high fiber count ribbon cables come to play. These compact, UV epoxy bonded cables are comprised with high precision optical fibers and can be massed fusion spliced with minimum loss. These products have proven to be an excellent platform for FTTH deployment.

Mass fusion splicing machines from Japanese companies are a integrated part of this process. These fusion splicers are used by the fiber installation technicians to splice up to 24 fibers at a time with very low splice loss.

Ribbon Fiber Design

The most basic requirement for any fiber optic cable design is to protect the glass fibers inside from harsh environment. But for ribbon fibers, there is the other vital requirement: organize the fibers for optimum space efficiency and ease of mass fusion splicing and handling. And at the same, they must also be able to maintain the optical performance and mechanical reliability.

This means that ribbon fiber cables must pack high count of glass fibers, organize fibers precisely for mass fusion splicing, provide individual fiber identification, can be divided into single fibers or subunits, mechanically reliable and can be easily accessed from the end or midspan.

These requirements must all be met at the same time which makes the manufacturing of high quality ribbon fibers a tough task.

So fiber cable specialists concluded a excellent design. A color coded array of fibers bonded in a line with fiber coating material. Based on this fundamental structure, two designed emerged: edge bonded or encapsulated.

Edge Bonded Design

The edge bonded design basically bonds the fibers together with only materials in between of each fiber. This design is more popular in the United States. This design is 40% smaller than the encapsulated design.

Encapsulate Design

In encapsulate design, bonding materials extend well beyond the gaps between fibers, it actually encapsulates all fibers inside a rectangular looking tube. This design are more used in Japan.

Ribbon Fiber Mass Fusion Splicing

The time savings for ribbon fiber mass fusion splicing are so big that sometimes in the field individual fibers are ribbonlized to make mass fusion splicings.

However, the success of mass ribbon fiber splicing relies critically on the fiber geometry, the ribbon and the mass fusion splicer. High quality and consistent mass fusion splices can only be produced with ribbons that are made from fibers having stringent geometric tolerances.

These high quality fibers and ribbons are already commercially available. And they make the fiber deployment in FTTH projects a joy for the installers.
