    MoCA: Carry Data & Video over Coaxial Lines

    MoCA stands for Multimedia over Coax Alliance. It’s a technology that enables coaxial lines (provided for Cable TV) to carry data, voice and video inside a home/small office. It’s an alternative to wired/wireless/powerline networking technologies. Advances in home networking segment (such as this) might have applications in remote offices/factories, as well. For example, if a remote home-turned-office has coaxial cables running within, it is possible to create a computer network (LAN) using it, with MoCA adapters that can carry data, voice and video. Wired network (using copper twisted pair cables – Cat 6/7) is the best option any day. But it may not be required at all places, and creating…

    A Short Note on PCI, PCI-X and PCI Express

    PCI refers to Peripheral Component Interconnect. PCI is a standard that provides high performance I/O interconnect technology which enables data transfer between a motherboard/CPU and its peripherals/add-on components. In this article let us look at a short introduction of the three main PCI standards – PCI, PCI-X and PCI Express. But before that let us look at some devices that could be connected to the CPU using PCI standards – Wi-Fi Cards, Bluetooth devices, Network Interface Cards (NIC), Modems, Sound/Graphics cards, Storage/disk controllers, TV tuner cards, Analog/Digital interface cards for IP Telephony, etc. Actually, PCI slots are available in PC/server and PCI connectors are available with these devices. One can…

    POE+ (IEEE 802.3at) powers network devices that require higher power

    We all know about the POE Standard (IEEE 802.3af). It is used to provide electrical power along with data using the ethernet (cat x) cable that connects to the network device so that a separate power cable is not required to power the device. But, there are certain network devices that may require higher power to be provided through the ethernet ports, than what is offered by IEEE 802.3af/POE. A standard called POE+ or IEEE 802.3at is used to provide that additional power to compliant devices. The convenience and perhaps cost/power saving of POE (Power Over Ethernet) technology has enabled many companies to power up their access points/ IP Phones,…

    You can use Optical Taps to monitor Fiber Cables/ Optical Network

    Optical Taps are passive devices that enable one to monitor Optical fiber links to identify faults & help trouble shoot an Optical network. They are generally placed in-line (in-between) the two devices that are connected with an optical fiber cable. Let us learn more about Optical Taps, in this article.

    What is FTTH – Fiber To The Home & Advantages of P2P vs P2M/PON Architectures

    Enterprise Fiber Networks seem to get the raw deal these days! Fiber To The Home (FTTH) can get Fiber Cable up to the Desk of a person accessing Internet at home & they can send and receive signals on the same fiber strand! Let us take a closer look at the two popular architectures that seek to dominate the FTTH market - P2P (Point to Point) & P2M / PON (Point to Multi-point), along with some advantages of each.

    Universal Power Over Ethernet (UPoE) technology delivers up to 60W of Power per port

    What is UPoE (Universal Power over Ethernet)? Power over Ethernet is a commonly used technology for powering IP phones, Access Points, IP Cameras, etc using just the data cables. So, data and power are transmitted through the same Cat 5/6/7 twisted pair cables eliminating the need for a separate electrical network. The Universal Power over Ethernet takes takes this technology a couple of steps further and delivers a higher power output capacity of up to 60W per Ethernet port. Of course, this technology is proprietary to Cisco and it works only on certain Cisco Switches and their partner ecosystem devices right now. The UPoE technology uses all the four pairs…

    Why not use Bend Insensitive (BI) Fiber Cables for enterprise applications?

    With Fiber To The Home (FTTH/x) becoming a popular method to access high speed broadband connections, Bend Insensitive (BI) Fibers are being commonly used for the FTTH/x access networks. Basically, Bend Insensitive Fiber Cables can perform well even if they are bent beyond their recommended bend-radius, during the installation/ maintenance. But why not use Bend Insensitive fiber cables for enterprise applications as well?

    Advantages and Limitations of Optical Fiber Cable/ Communication

    An overview of Optical Fiber Cables/ Communication is given in the above Infographics. You can find a more in-depth technical information about OFC here. There is also a nice flash presentation outlining the basics of Optical Fiber Cables/ Communications here. What you can expect to read in this article though, are the advantages and dis-advantages/limitations of Optical Fiber Cables/ Communication especially over Copper UTP Cables for creating Computer Networks.
