Does it have a load balancing core switch
This type of switch helps optimize resource use, enhance performance, and improve the reliability of applications by ensuring that no single server is overwhelmed with too much traffic. A Load Balancing Switch is a networking device that manages and distributes incoming network traffic across multiple servers or resources. It operates at various levels of the OSI model, often functioning at Layer 4 (Transport) or Layer 7 (Application), depending on the complexity of the traffic. This document describes the EtherChannel algorithm for load balance and redundancy on Cisco Catalyst switches. There are no specific requirements for this document. This document is not restricted to specific software and hardware versions.

Distance Power Calculation of Optical Transmitter
Enter your fiber type, distance, connectors, splices, and components to calculate total optical loss, link margin, and power budget with engineering-grade accuracy. Add each MUX or DEMUX on the path. Choose a preset for typical insertion loss, or enter a custom. Design and validate fiber-optic links in seconds. When powers are in linear units, the loss in decibels is: Attenuation (dB) = 10 × log10 (Pin / Pout) If the link length L is provided, the attenuation coefficient is: Coefficient (dB/km) = Attenuation (dB) / L (km) For dBm. Given an optical transmitter and receiver set, the most important question concerning a system designer or integrator is the maximum implementable link length. The power budget refers to the amount of fiber optic cable plant loss that a datalink (transmitter to receiver) can tolerate in order to operate properly.
