The maximum frequency suitable for transmission over Cat 2 cable is 4 MHz, and the maximum bandwidth is 4Mbit/s.〔Meyers; Page 69.〕 Cat 2 cable contains 4 pair of wires, or eight wires total.〔Carpenter; Page 231.〕 Though not an official category standard established by TIA/EIA, Category 2 has become the de facto name given to Level 2 cables originally defined by Anixter International, the distributor. Official TIA/EIA-568 standards have only been established for cables of Category 3 ratings or above. Anixter ''Level 2'' cable was frequently used on ARCnet and 4 Mbit/s token ring networks, it is also used in telephone networks but it is no longer commonly used. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Category 2 cable」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
