By reducing the original signal rate to 1 ⁄ 4 or 1 ⁄ 2, the link speed drops to 2.5 or 5 Gbit/s, respectively. [5] The spectral bandwidth of the signal is reduced accordingly, lowering the requirements on the cabling, so that 2.5GBASE-T and 5GBASE-T can be deployed at a cable length of up to 100 m on Cat 5e or better cables.

Cross section of a cat 5e cable. The Category 5e specification improves upon the Category 5 specification by further mitigating crosstalk. [9] The bandwidth (100 MHz) and physical construction are the same between the two, [10] and most Cat 5 cables actually happen to meet Cat 5e specifications even though they are not certified as such.

The Consumer Technology Association (CTA) has warned that Trump's proposed tariffs could lead to higher prices for smartphones, laptops and tablets, connected devices, video game consoles, and ...
Each 1000BASE-T network segment is recommended to be a maximum length of 100 meters (330 feet), [5] [a] and must use Category 5 cable or better (including Cat 5e and Cat 6). Autonegotiation is a requirement for using 1000BASE-T [ 6 ] according to Section 28D.5 Extensions required for Clause40 (1000BASE-T) . [ 7 ]
From January 2011 to December 2012, if you bought shares in companies when Anne M. Finucane joined the board, and sold them when she left, you would have a 37.9 percent return on your investment, compared to a 12.1 percent return from the S&P 500.
