Understanding and Selecting Optical Fibre and Cable

This document will provide an understanding of optical fibre, optical fibre cable (OFC), application standards, and key considerations that one should make before selecting optical fibre products. Typically, the first document shared with a user (Purchasing Manager, Technical Manager, and Installation Manager) is a technical datasheet. When several optical fibre cables are to be compared, as per the requirements of a project, a short list could be created based on the datasheets. However, all datasheets are not equivalent even if they look similar. One should know what the minimum relevant data are, how to find them, and how to compare them...

Beyond the Human Threshold

As 5G network deployments continue to ramp up, communications service providers (CSPs) continue to look for new ways to extract value from their core networks and radio access networks (RANs). A vital element of this exercise will be how to achieve further service differentiation from previous mobile generations such as 4G. While this process will be gradual, the 5G core (5GC), which adopts a services-based architecture (SBA) that supports application programming interface (API) exposure, will drive the next wave of mobile service innovation. Two key components critical to the process of monetizing 5G innovative services are policy control and charging...

The Role of the RAN Intelligent Controller in Open RAN Systems

The RIC is more than a RAN controller, however. It is also an open platform that can host RAN control applications developed by specialist software suppliers that are external to the RIC vendor itself. These "xApps" (near-RT) and "rApps" (non-RT) are among the primary reasons why the RIC is a compelling component of the O-RAN architecture. XApps and rApps will enable innovation-in the form of RAN control algorithms-to enter the RAN at a pace that is orders of magnitude faster than is the case with today's vendor-proprietary systems or centralized SON methods. Such innovation will help operators create differentiated network experiences that offer performance adapted to particular service types, user groups, or locations...

Are Networks in Emerging Markets Ready for Terabit/s Scale Optics?

With the adoption of capital intensive 10-100 Gb/s transmission systems in many emerging markets such as India, the requirement of a predictable delivered OSNR in the outside plant is of paramount importance. In such economies, intense construction activity and poor installation practices lead to severe restrictions on predictable signal quality. Optical attenuation levels rise considerably beyond the beginning-of-life (BOL)/time of installation values. As a consequence of increased attenuation and the change in received OSNR (ROSNR), premature link failures especially at 100Gb/s 200Gb/s and increased costs due to cable replacement are an operational reality. Service providers in these markets are challenged in the optimal allocation and utilization of network routes...
