近日,TIA TR-42工程委员会一致批准将TIA/EIA-568-B.3光纤布线部件标准公布。这个资料是用于取代TIA/EIA-586-A商用建筑布线标准的新的电信标准系列的第三部分。新标准完成后,TIA商用建筑布线标准的第三稿将包括: TIA/EIA-568-B.1(‘568-B.1)布线系统总论 TIA/EIA-568-B.2(‘568-B.2)100欧姆平衡双绞布线
Recently, TIA TR-42 Engineering Committee unanimously approved the standard announcement of TIA / EIA-568-B.3 optical fiber wiring components. This information is the third part of a new series of telecommunication standards that supersedes the TIA / EIA-586-A commercial building wiring standard. After the completion of the new standard, the third draft of the TIA Cabling Standards for Commercial Buildings will include: TIA / EIA-568-B.1 (’568-B.1) Cabling Systems General TIA / EIA-568-B.2 -B.2) 100 ohm balanced twisted pair wiring
