AT&T to Begin Testing Siemens Optical Transport

AT&T Labs will begin testing Siemens' next-generation optical transport solution for use on high-capacity routes in its network. The test marks the first Siemens deployment in the AT&T transport network. AT&T has expressed its intent to evolve to one global network using MPLS on an optical backbone.


The Siemens SURPASS hiT 7500 offers full-channel optical add/drop multiplexer capabilities, enabling remote configuration of a path without the need to touch the network while staying all-optical through multiple add/drop nodes. The Siemens system also features transponders that are tunable over the full 80 channels of light, resulting in quicker wavelength provisioning. The platform also extends the distance between signal regeneration points to more than 900 miles.
