When choosing fiber optic cables or fiber connectors, you may find that the description of the product noted the word “PC Polish”, “UPC Polish” or “APC Polish”. What do these words mean? What’s the difference between these connector types? This post will shed light on these connector types and their differences for you. Introduction to […]
As we know, there are a large number of fiber optic cables used between devices in optical communications, and the optical connectors of fiber cables are required to be reliable for high-performance optical fiber networks. When measuring the attenuation effects of the fiber connectors, insertion loss (IL) and return loss (RL) are two essential parameter […]
What Is DSL? DSL is short for Digital Subscriber Line. It is one of the oldest Internet technologies which is used by homes or businesses to send and receive data via copper telephone lines. It seems much like dial-up because they both use your phone line to transfer data and connect you to the internet. […]
Why Fiber Optic Cables Need Lightning Protection Systems? Lightning is an electrical discharge within clouds either from cloud to cloud or from cloud to the earth. It has great impacts on communication stations and other signal circuits. For example, it will not only affect all DWDM fiber channels in short bursts, but also affect transmission […]
It’s known to us that the concentration of water moisture in fiber connectors will lead to glass damage and severely affect the performance of optical cables. To prevent fiber from contaminating by water is a critical concern in outdoor cabling. Luckily, with the advent of the IP67 waterproof fiber connector, excellent water protection can be […]
Designed for harsh environments, armored fiber optic cables, IP67 waterproof fiber optic cables, military-grade fiber optic cables, and FTTA patch cables are all available in the market to meet the corresponding demands. A comprehensive guide will introduce these types of optical fiber patch cables respectively. Why Ruggedized Fiber Optic Cable Matters? When conducting cabling deployment […]
Fiber optic cable, which is lighter, smaller and more flexible than copper, can transmit signals with faster speed over longer distance. However, many factors can influence the performance of fiber optic transmission. Losses in optical fiber are negligible issues among them, and it has been a top priority for every engineer to work with and […]
ITU-T G.65x series is a commonly known single mode fiber standard category, which can be further divided into G.652, G.653, G.654, G.655, G.656, and G.657, among which G.652 and G.655 are the two options commonly used. G.652 vs G.655 fiber, what are their differences and how to make a wise decision between them? Basics and […]
Accurate measurement and testing in fiber cable installation are crucial to ensure overall network integrity and performance. A significant signal loss in the optical fiber can cause unreliable transmission. How can we know the value of losses on the fiber link？Read on, this post will teach you how to calculate the losses in optical fiber […]
Why Should We Use Pulling Grip? On many occasions, if the pulling distance is short (less than 3000 ft) and the pathway is straight enough, one can pull a fiber optic cable by hand without the help of any tools. Only when additional mechanical force or distance of long term is needed for a pull, […]
