AT&T deploys 100 Gbps optical wavelength using open ROADM
AT&T has successfully tested a network switch with software control and open hardware specifications in a live environment
AT&T has successfully tested a network switch in a live environment with software
control and open hardware specifications.
Andre Fuetsch, CTO at AT&T Labs, has claimed that AT&T has implemented
a 100-gigabit per second optical wavelength switch on a production network
using open reconfigurable optical add/drop multiplexer-compliant technology.
The experiment included the connection of two IP multiprotocol label switching
routers with transponders and ROADMs. The kit was from Ciena and Fujitsu.
Fuetsch said this was the first multivendor interoperability for optical
transport equipment carrying live customer traffic. The test was done, according
to Feutsch’s blog, in the Dallas area in a live environment with the ROADMs
supporting “full software control according to the published open ROADM
The carrier noted application program interfaces and information models
defined in the open ROADM specification were used to control and manage the
optical network. The 100G wavelength provisioned using a software-defined
networking ROADM controller developed by Fujitsu and integrated into the
AT&T enhanced control, orchestration, management and policy platform.
Ciena and Fujitsu are both part of AT&T’s Domain 2.0 program.
AT&T has said it has plans
to expand the ROADM platform across its network in support of new services.
