Once in place on authorized Synchronous Optical Networks (SONET), users will experience significantly less network delay, or latency, common to securing large information files.

一旦获同步光纤网络(SONET)授权，将显著减少用户网络延迟或等待的时间，确保大型信息文件安全。

The access network and inter-exchange transport of the PSTN use synchronous optical transmission (SONET and SDH) technology, although some parts still use the older PDH technology.

PSTN中的接入网和内部交换台传送器采用的是同步光纤传输(SONET和SDH)技术，但也有某些地区仍采用过去的PD H技术。

Metro networks have phone gear like digital cross-connects, which manage high-and low-speed traffic, and synchronous optical network (Sonet) systems, which come from fiber-optic phone networks.

Crosswave uses synchronous optical network (sonet) and wavelength division multiplexing (dwdm) technologies, which enable it to transmit data at high speeds over long distances with a high degree of reliability.
