Abstract

A data center network device provides configurations where the port density can be increased by incorporating multiport transceivers within the device and the use of high density fiber connections on exterior panels of the device. The device also permits dynamically reassigning fiber connections to convert from single fiber connection paths to higher rate bonded fiber paths while at the same time making more efficient use of the fiber interconnections.
