The digital era is driving the need for increased transmission speeds and bandwidth. Big Data and the Internet of Things (IoT) are fueling the change from 10 gigabits per second (Gb/s) to 40 and 100. Both 40 and 100 GB/s transmission use plug-and-play MPO/MTP trunk assemblies to enable faster deployment and to handle larger amounts of complex data from more than one source. In the face of next-generation transmission speeds, data centers need to optimize their overall fiber cabling performance. They need to understand the differences in quality between types of fiber.
