The pair of pins TXin+ and TXin−, for a differential transmission signal, are provided base on a common mode impedance structure, to charge capacitors carried by the TX+ and TX− terminals and, according to the charging status of the capacitors, it is determined whether the active optical cable is connected to the apparatus. | 2013-05-23 |
