The first claimed demonstration of 100 Gigabit Ethernet has been announced by a group of companies spanning the telecom industry. Internet2, Level 3 Communications, Infinera, Finisar and the University of California at Santa Cruz (UCSC) all collaborated on the project.
A 100GbE demonstration involves sending a signal via ten 10Gbit/s channels over a 4000km network. The demonstration uses Finisar’s 10Gbit/s optical transceivers and Infinera’s 10x10Gbit/s photonic integrated circuit. Level 3 provided the ten 10Gbit/s channels. The demonstration bonds the 10G channels into one logical one, and ensures packet ordering at the receiver is retained, which is the UCSC's contribution.
This is the second announcement involving Finisar and Infinera recently. The two are also part of the X40 40Gbit/s multi-source agreement group.
Meanwhile, work on the standard for 100Gbit/s Ethernet is still in its infancy. The choice of how it will be implemented, whether 10x10Gbit, 5x20Gbit/s 4x25G channels or even a single 50G link with advanced modulation, has yet to be decided.
