Patent ID: 8098661

Claim:
A datacenter comprising: a number of at least 5×K Ethernet network elements (ENEs) operating at a bit rate of substantially 40 Gb/s, where K is a positive integer; a number of at least 2×K optical transceivers operating at a bit rate of substantially 100 Gb/s, each of the optical transceivers comprising a 5:2 electrical interface which enables translation between bit rates whose ratio is represented by the ratio 5:2; and an interconnection switch operatively associated with the ENEs operating at the bit rate of substantially 40 Gb/s and with the optical transceivers and comprising: a controller; and a switching/routing unit operatively controlled by the controller to interconnect electrical lanes of a number 5×K of the ENEs operating at the bit rate of substantially 40 Gb/s with 5:2 electrical interfaces of a number 2×K of the optical transceivers so as to bypass communication interfaces of the 5×K ENEs and to enable use of at least one of the 2×K optical transceivers for communicating data between at least one of the 5×K ENEs interconnected with the at least one of the 2×K optical transceivers and at least one ENE operating at a bit rate of substantially 100 Gb/s.
