Understanding the condition of the PCS lanes is crucial to troubleshooting 100G links during network deployments. At the most basic level understanding that there are errors at the PCS indicates that the root cause of the fault lies with the physical signalling and not at the MAC layer or any of the high network layers…(Read More)

Unlike previous pluggable transceiver modules there is a real requirement to test the CFP in a staging area prior to deployment. Previous devices such as the SFP or XFP currently are available with commodity pricing from almost $50 to a a few thousand dollars depending on the required interface support. In comparison the CFP can…(Read More)

A New Sublayer

by

The multi-lane architecture within 100G Ethernet that comprises the PCS Lanes, CAUI and Gearbox (depending on CFP) represent a whole new sublayer of the network that must be specifically tested. This new sublayer exists only between two directly adjacent network elements that are connected via the CFP interfaces. To support this there are a…(Read More)
