Well I like the HP brand, but the memory and other things is very low compared Dell. I am in 8 grade, and I'm saving for a laptop for next year .. My price range is under $ 700 .. Should I invest in another 100-200 dollars? I'm not sure you need a laptop powererd very high, because Its just for school, and Mabey a game like The Sims 2. http://www.dell.com/content/products/features.aspx/lighter_laptops?c=us&cs=19&l=en&s=dhs Travel http://www.shopping.hp.com/ webapp / Purchasing / computer_can_series.do? computer_store storename = & category = & a1 = Category & v1 = Ultra-Portable & = Series_Name dv4t_series What experiences have you had with this Labtop? Labtop What do you recommend? Should I invest in a better laptop? http://www.shopping.hp.com/webapp/shopping/computer_can_series.do?storeName=computer_store&category=notebooks&a1=Category&v1 = Ultra-Portable and Series_Name = Dv4z_series must be portable, by virtue of 12-14 inches?
I have tried all major brands and minor. I recommend first Lenovo Thinkpad, Panasonic Toughbook second.
Installation of fiber optic cable is a very special task that only trained professionals can quickly and correctly. It is determined by the fragile structure and highly sensitive fiber and microbending loss Macrobending.
However, most of the installation of fiber cable optics have been taken from those used for copper cables. And now most entrepreneurs fiber cable from the base the copper network.
Fiber cables can be divided into two groups: cables and son outdoors inside. Cables field are laid along rights of way, leased or owned telecommunications companies, and are well marked after the installation cables. Telecommunications companies have their own team of cable installers and often subcontract work to independent contractors.
Most independent contractors to install fiber cables installed Most of the time indoors. Indoor cables fibers are used mainly as backbone for campus networks, systems, corporate LAN, etc.
And is the category of submarine cable. They are provided for vessels built for this purpose. They are only used by major global manufacturers in the skeleton.
But in reality there are many smaller divisions within each group. We discuss one by one.
1. Submarine cables. Submarine cables are placed usually constructed for that purpose. They are buried in a pit dug on the seabed at depths of less than 200 meters. In deeper areas, of submarine cables are collected at the bottom of the ocean.
2. Direct buried fiber cables. Direct buried cables are also called shielded cables. They are foil wrapped some mechanical protection from the bite of a rodent and external forces. To be placed in a deep trench dug with a cable plow and then covered with earth.
3. For external cables except cable directly buried, you need the cable sheathing. Cable ducts are tubes of plastic, which provides a channel access and protection of cables outside. They are buried in trenches, then covered with earth. Cable ducts have a variety of sizes and flexibility, which can range from one inch to 6 ~ 10 inches. Some are flexible, while others are quite rigid.
4. Cable trays are buried for the first time without the need for fiber inside. They can be sent directly between two ends or through a series of points of manholes.
5. The cables to the air are attracted to cable ducts with a rope pull. By pulling the rope is attached to members of the force of the cable, then removed destination. Never be eliminated directly, because the fibers that the fibers break easily and lead to a broken cable useless to you.
6. And then there are the antenna cables. A type of antenna cable of a line of integrated messaging that provides mechanical support and may be hung on the poles without wetting. This type of antenna cable is called or self-supporting figure 8 cable. Other types of antenna cables must be struck with a special link cable running around the cables and son Messaging separately.
7. Indoor cables can be installed inside walls, through the cable bands, or elsewhere in the building. Note: Only under special cable fiber carpet should be used for placement on the floor where people walk.
8. A particular type of cable is called inside Plenum cable. They have special coating material for the assessment of fire. Only cable can be used in plenum spaces for air return system ACC.
We covered a lot about installing fiber cable in this short article. He warns -- you should always consult some training materials on the installation of fiber cable before you try it yourself!
