XO conducts coherent 100 Gbps optical network trial

XO Communications (OTC BB: XOHO.OB) has just completed its trial of 100 Gbps coherent optical transmission on a 1348 km route on its U.S. network.

During the trial, XO leveraged Infinera's (Nasdaq: INFN) 500 Gbps photonic integrated circuits (PICs), which integrate five 100 Gbps channels. The Infinera 500 Gbps PICs transmitted and received a 100 Gbps signal on a 1348 production network between the Denver and Dallas segments of its fiber network.

Built with Infinera's 100 Gbps-ready ILS WDM line system that it claims can scale up to 8 Tbps of fiber capacity, the system simultaneously carried 10 Gbps and 100 Gbps channels. To gain error-free urepeatered transmission over ultra-long haul distances like XO's Denver to Dallas route, the 100 Gbps channel was transmitted using PM-QPSK modulation and coherent detection.

Not surprisingly, XO, an aggressive advocate of optical-based network services that's been leveraging Infinera in its optical network, sees the trial as s proof point to leverage 100 Gbps systems to meet its business and carrier customer needs.

"XO Communications looks forward to the increased capacity and superior efficiency we anticipate these 100G systems will deliver, as we work to meet growing bandwidth demands from our enterprise and wholesale service provider and mobile wireless customers," said XO Communications Chief Technology Officer Randy Nicklas in a release.
