Communications Cable Ratings
When purchasing our Ethernet cables (Cat5e, Cat6, Cat6a), you may come across the following markings located on the cable or product listings: CM, CMR, CMG, CMP, CMX. These are cable markings that are used by the National Electrical Code or NFPA 70 when referring to their standards. In this post, we will be doing a quick overview of each of these common markings.
1. CM rated cables meet the UL 1685 standard and are suitable for gen
At PI Manufacturing, we carry a large selection of cable ties, ranging for use in residential or commercial applications. Before purchasing a cable tie for your application, make note of the tensile strength.
Understanding Tensile Strength
The minimum tensile strength is the load capacity or weight a cable tie can hold. This is determined according to the Military Specification and Standards of the USA. When a cable tie listing includes the minimum tensile strength, this shows the weight that it
Differences Between OM3 and OM4 Fiber
When deciding between OM3 and OM4, here are a few considerations for you to take into account.
OM - Optical Multimode
Used for short distances, Optical Multimode (OM) is a type of optical fiber with a large core diameter that allows multiple modes of light to propagate inside the core. This allows more data to pass through, however due to the amount of light being reflected and the attenuation that accompanies it, this type of fi
