Upgrade Your Cabling Infrastructure to 100G – Part 1

Multinational companies’ bandwidth demand is rapidly growing, and data centers must upgrade their computing, networking, and storage capacities. As a result,  10G/25G to 100G migration is an irreversible trend. Thus, the optical cabling system of migrating data centers must be upgraded. The following will guide designing your data center’s optical cabling for 100G Ethernet.

100G Ethernet Needed


The growth of emerging technologies, including 4K/8K video, 5G, big data, cloud computing, and IoT, generate vast volumes of and increase bandwidth demand. In addition, convergence, high-performance computing (HPC), routing & switching, and virtualization will need more incredible network speeds in data centers. Both 1G and 10G are having trouble meeting the demands of each of these high-bandwidth applications, making migrations to 40G/100G networks necessary.


For data centers to function well, their cabling infrastructure must be reliable, manageable, and scalable. Dependable network connections and day-to-day ease of management can ensure the high uptime of data centers. Scalability enables a data center to support future greater bandwidth demands.


100G Data Center Optical Cabling Design


As discussed below, setting up a high-performing and efficient 100G data center cabling system requires designers to consider several cabling infrastructure aspects.


High Bandwidth


A modern data center requires high bandwidth to cope with today’s volume of network traffic. Thus, the cabling infrastructure of data centers must support a greater bandwidth. Design of internal data center topology and external network connections is required to provide adequate network capacity.


Low Insertion Loss


A crucial performance measure, insertion loss, must be considered for data center cabling deployments. Insertion loss can occur on every connection point along a cable run. When insertion loss is excessive, it can keep a device on the far end of the line from receiving and interpreting signals correctly. Performance can be improved by lowering insertion loss.


Low Optical Skew


The measure of light propagation time across fibers, optical skew, is essential for parallel optics transmissions. Transmission errors are more likely to occur when there is excess delay or skew over various channels. Connectivity solutions can ensure improved skew performance, ensuring sufficient fiber optic cabling capability over several applications.
