The Ultimate Guide to Fire Ratings for Communication Cables: CM, CMR, and CMP Explained

The NEC (National Electrical Code) defines three major fire rating categories for communication cables: CM, CMR, and CMP.But what exactly do these ratings mean? How do CM vs. CMR differ? Can CMR cables be used in plenum spaces? And when should you choose CMP? Let’s break it all down.

MPO vs MTP Cable: What’s the Difference and Which One Should You Choose?

When dealing with high-density fiber optic cabling, terms like MPO and MTP often come up. At first glance, they may seem interchangeable—but there are subtle yet important differences. Understanding MPO vs MTP cables is critical for choosing the right solution for your data center, telecom network, or enterprise backbone.

MPO to MPO Cable: High-Density Fiber Connectivity for Modern Networks

An MPO to MPO cable is a multi-fiber optical cable terminated with MPO (Multi-Fiber Push-On) connectors on both ends. Unlike traditional single-fiber connectors, MPO cables can accommodate 12, 16, 24, or even 32 fibers in a single connector, making them ideal for high-density data center environments.

Fiber Trunk Cables and Leviton Fiber Enclosures: A Complete Guide for High-Performance Networks

As modern enterprises scale their data centers and communication networks, the demand for fiber optic trunk cables and reliable termination solutions has never been greater. High-density connectivity requires efficient routing, protection, and management of optical fibers. This is where fiber trunk cables, fiber optic trunk lines, and Leviton fiber enclosures play a critical role.

Romex vs. MC: Choosing the Best Cable for Your New Wiring Project

When you're choosing electrical cable for a modern wiring project, you'll typically be looking at two main types: Non-Metallic Sheathed Cable (Romex) and Metal-Clad Cable (MC cable). These are the modern-day alternatives to old BX cable, and each is suited for a different job.

What is Old BX Cable? How to Identify and Safely Handle It

If you live in an older home, you might have discovered a unique type of electrical wire in a hidden corner: BX cable. This vintage armored cable is a common feature of old houses, but it comes with unique safety concerns. Learning how to identify and properly handle it is crucial for keeping your home safe.
