Fiber Optics in the LAN and Data Center

Title:

Description:

We will cover OM1-OM4 multimode cables, and introduce the new OM5 cable for 100-400G.  Understand cable connectors used in LAN and today's Data Centers.   Build a modern transceiver, and learn about SerDez and the critical ASIC chips that drive higher speeds in the Data Center.

A critical view of the cost/benefits of transceiver options.   Look at the MPO/MTP connectors and how they transform fiber density.
