Dynamic bending during optical cable laying
Excessive bending causes light leakage from micro cracks in the fiber cladding, resulting in data loss and signal attenuation. Fiber optic cable bend radius is a critical mechanical parameter that determines how sharply a cable can be bent without risking microbending, macrobending, signal loss, or long-term structural fatigue. Proper bend radius control ensures the integrity of optical performance and protects the glass. All fiber optic cables have specifications that must not be exceeded during installation to prevent irreparable damage to the cable. This Applications Engineering Note (AE Note) addresses application and selection considerations for improved bend performance optical fibers (IBP fibers). Particularly with modular systems such as VarioConnect and SlimConnect bending radii must be precisely dimensioned for different guide levels and cable types.

Load Balancing of Layer 3 Core Switches
Dynamic Load Balancing (DLB) is an advanced and intelligent hashing mechanism that dynamically directs traffic over underutilized links. This occurs at the IP layer (Layer 3 in the OSI model) and is often implemented in modern networking hardware such as Nexus 9000 series switches. While application load balancers can be used to distribute load across across an array of devices for a particular application or purpose, this article will. Currently only the EX3300 connects to our WAN Router and is trunked via 4 LACP links to the HP2848.
