The installation was supposed to be an easy task. In the course of six months, Marcus Chen designed the upgrade of his data center to 100G, bought the necessary tools and parts, and agreed on the best time for the maintenance. He didn\u2019t, however, foresee difficulties in connecting new spine switches once the operation started.<\/p>\n\n\n\n

They were supposed to connect full MO MPO trunk cables (MPO to MPO), which \u2013 instead \u2013 had one MPO connector and multiple Individual Single Server Managed Interconnect \u2013 Individual Connectors (there was no such breakout). And all these trunk cables were still in their boxes, not being used. The cables that they actually required were breakout cables, and it takes another week before they arrive. The Acting Equipment Manager sighed in despair. The additional funds of USD 40,000 were wasted because of delays and high rates of air freight services.<\/p>\n\n\n\n

It is easier said than done when dealing with MPO trunk vs breakout cable since this decision is rather more fundamental as far as data centers are concerned, and their practicability, efficiency, and scalability are concerned. In the wrong place, the wrong type of MPO cables suffocates the system. However, using them where necessary cuts costs and facilitates any other improvement.<\/p>\n\n\n\n

This document will help you understand when and why it is necessary to use trunk cables or breakout cables. Questions such as \u2018How do we identify structural differences between trunk and breakout cables?\u2019, \u2018What structural function do we consider before deciding which one to use?\u2019 and \u2018How expensive or cheap will this decision be?\u2019 are answered in this guideline. It doesn\u2019t matter if you are installing a new network or renovating an old one, you will be able to make decisions on which connections require which cables.<\/p>\n\n\n\n
