Fiber Optic Jumpers , also known as Fiber Patch Cords are the cables that connect network hardware or end devices to your cabling system. These cables terminate with MTRJ, LC, SC, or ST connectors at each end. The jumpers come in simplex and duplex types and can be selected depending on your network requirements. Here are some insights on Fiber Optic Jumpers and considerations you should make before buying them. Simplex vs Duplex Jumpers If you see Simplex Cables, you will notice a strand of glass enclosed in plastic. These cables are used when you need to do data transmission in one direction. When you need to establish connections within buildings or huge cable TV networks, they are a right choice. Duplex cables, on the other hand, have two strands of fiber in a single cable. These are used for bidirectional transmission, between your device and cable. When one cable transmits signal, the other one receives it. You will observe Duplex cables being used at large workstations, ...

Whenever you want to supply electricity to different types of networking, computing devices and AV without an adapter, Power Over Ethernet (PoE) technology works the best. Also, it lessens the number of building materials needed to connect and power a device through a single cable which takes care of both the services. As the powered devices of today are no longer restricted to security cameras and VoIP phones such devices utilize Power over Ethernet connections. These devices also need high power levels. A new Power Over Ethernet (PoE) standard called – IEEE 802.3bt, supports up to 100W of power per cable. Sometimes, if high power is running through a cable, it can cause performance issues by making the cable hot leading to high insertion loss. In order to curb this phenomenon from affecting productivity, Ethernet cables like CAT5 cables and   CAT6 cables   are used. But the best cables to use during such times are   CAT 6A cables . Here’s why: 1. They cause less...

If you look at computer hardware and accessories keenly and try to identify them, you will find yourself overwhelmed by product descriptions, features and their abbreviations. Sometimes the product descriptions are abbreviated and users are expected to research and understand things about them on their own. And it gets even tougher if you are asked to set up the system. As there are plenty of   computer cables   available in the market today and a lot is written about them, it is difficult to find a common resource which brings forth the common differences between them. Here’s a small guide to all the computer cables and their features. 1. VGA- Video Graphics Array VGA cables were designed in the 1980s and they were standard cables which were used to connect computer to the monitor. These cables have 15 pins that are arranged in 3 rows with 5 pins in each row. Each row corresponds to 3 types of colours including red, green and blue. As people started preferring digital...

Often when you go to purchase a power cord for your electronic device; be it online or offline, you have to choose one out of both mechanical and molded   power cords . A molded cord (also known as over-molded cord) is designed by using an injection molding process which uses a combination of two or more materials along with plastic to build a single part. The materials become more flexible and robust when they undergo this type of molding process. Also, they enhance the reliability of the product. A mechanical cord (also known as an assembled one), on the other hand is made out of elements that should be hard wired before putting them to use. This connector is then manually connected to the cord. While making assembled cords, labour intensive procedures are applied. Tools are also used to open the casing as well as other electrical assemblies like wiring. Utility and purpose of both power cords 1. Molded Power Cords Molded Power Cords are quite flexible. Hence it becomes...

When it comes to travelling or studying abroad, we often tend to overlook the departure guide us about the   power converter and adapter   to carry. This blog post will be of great help if you have forgotten to look into some major aspects of electricity and you are planning to go for some adapter or converter shopping.
