IBM研究所的波特·奥弗林(Bert Offrein)解释说，为了加速传输数据流需要在信息处理之后就近将电子转换成光子。

To speed up the flow of data, electrons need to be turned into photons "as close as possible to where the signal is processed", explains Bert Offrein of IBM Research.

等时传输：这些是实时的数据流，它们对带宽的要求高于可靠性要求。

Isochronous transfers: These are data streams in real time with higher requirements for bandwidth than for reliability.
