Breaking the 100-Meter Barrier
It’s a common problem – you need to connect an end device that’s just a little too far from the nearest telecommunications room (TR). While industry standards limit the length of a channel to 100 meters, connecting the device maybe require a channel length of 150 meters or even 200.

OM の言霊
TIA は、ISO/IEC 11801 規格で使われているマルチモード・ファイバーの呼称の「OM」プレフィックスは、TIA により採用されています。
