At the European Conference on Optical Communications, Verizon Communication announced that it had tested interoperability of generalized multiprotocol label switching gear over its Verizon Business network with Ciena, Fujitsu and Tellabs. The telco claimed that it was the first time GMPLS had been tested over a commercial network. The test experience ultimately could help Verizon develop an external network-to-network interface to set up an optical path through another carrier's network feature package," says Bill Uliasz, Verizon's director of video systems integration.
As expected, Verizon also presented a paper with Nokia Siemens Networks on its 111 Gbps trial in Richardson, Texas, which set a distance record for that level of transmission. News of the trial first emerged earlier this month.
