How to connect a passive optical network PON

A single fiber-optic cable runs from the OLT to a nonpowered (passive) optical beam splitter, which multiplies the signal and relays it to many optical network terminals (ONTs). End-user devices such as PCs and telephones are connected to the ONTs. Passive optical networking (PON), like active optical networking, uses fiber-optic cabling to provide Ethernet connectivity from a main data source to endpoints. [pdf]

What does it mean when a switch restricts network segment access

What does it mean when a switch restricts network segment access

Port-based network access control (PNAC) blocks access to a network by denying communication between an unauthorized device and the network. When an unauthorized device attempts to connect to a network port, the switch or router that manages the port will deny access to the network. NAC verifies who and what is connecting, checks whether a device meets security. Segmentation is the practice of dividing a network into smaller parts called segments to improve security, performance, manageability, and compliance. Of organizations say segmentation is a priority. Enabling this feature keeps track of permitted source MAC addresses and restricts the number of MACs that can use a specific port. [pdf]

SOC network security devices

SOC network security devices

A SOC uses advanced technologies and standardized processes to protect an organization's digital assets. These tools typically include security information and event management (SIEM) systems, intrusion detection and prevention systems, and threat intelligence platforms. Organizations can build in-house, outsource to managed providers, or take a hybrid. Proactive security is a must to keep up with evolving cyberthreats and building a blue team program is the best strategy to incorporate proactive methods. This article explores the foundational elements of a Security Operations Center (SOC), which provides the infrastructure and expertise required. A security operations center (SOC) is a central team that oversees and manages an organization's security stance. Think of it as the command center for all cybersecurity-related activities within an.

How to secure network cables within a vertical cable tray

How to secure network cables within a vertical cable tray

In vertical or angled tray runs, cables should be fastened to the tray's transverse members to keep them secure. As a key support system for cable laying in building electrical engineering, the installation quality of vertical cable trays directly affects the safe operation of power, communication, and other circuits. This document, based on national standards such as GB 50303 “Code for Acceptance of. Article Summary: A compliant cable tray installation requires a thorough understanding of NEC Article 392, proper structural support, and precise installation techniques. This guide covers the critical steps, from selecting the right electrical cable tray and performing accurate cable fill. Unistrut systems are a very common type of cable tray support. Unistrut systems are very strong and highly flexible. Here's what you need to know: Cable Types: Only use. [pdf]
