  • How to Install or Remove SFP Transceiver Modules on Cisco Device

    The SFP (small form Factor pluggables) transceiver modules are hot-pluggable I/O devices that plug into module sockets. The transceiver connects the electrical circuitry of the module with the optical or copper network. SFP transceiver modules are the key components in today's transmission network. Thus, it is necessary to master the skill of installing or removing a transceiver modules to avoid unnecessary loss. This tutorial are going to guide you how to install or remove SFP transceiver module in a right way.

     

    Things you should Know Before Installing or Removing SFP

    Before removing or installing a Transceiver Module you must disconnect all cables, because of leaving these attached will damage the cables, connectors, and the optical interfaces. At the same time please be aware that do not often remove and install an SFP transceiver and it can shorten its useful life. For this reason transceivers should not be removed or inserted more often than is required. Furthermore, transceiver modules are sensitive to static, so always ensure that you use an ESD wrist strap or comparable grounding device during both installation and removal.

     

    Required Tools

    You will need these tools to install the SFP transceiver module:
    Wrist strap or other personal grounding device to prevent ESD occurrences.Antistatic mat or antistatic foam to set the transceiver on.Fiber-optic end-face cleaning tools and inspection equipment

     

    Installing SFP Transceiver Modules

    SFP transceiver modules can have three types of latching devices to secure an SFP transceiver in a port socket:
    SFP transceiver with a Mylar tab latch.SFP transceiver with an actuator button latch.SFP transceiver that has a bale-clasp latch.
    Types of SFP Latching

    Determine which type of latch your SFP transceiver uses before following the installation and removal procedures.

  • Straight-through, Crossover, and Rollover Wiring

    When talking about cable pinouts we often get questions as to the difference in Straight-through, Crossover, and Rollover wiring of cables and the intended use for each type of cable. These terms are referring to the way the cables are wired (which pin on one end is connected to which pin on the other end). Below we will try shed some light on this commonly confused subject.

  • Feds get huge response to request for IoT input

    More than 100 companies suggest ways U.S. government can help advance the IoT

    Many industry watchers feel the U.S. is slipping behind other countries, particularly Germany and China, in creating a unified national strategy for development of the Internet of Things or IoT. But federal leaders, in the early stages of involvement, reached out to the telecom industry for guidance.

    Back in April the National Telecommunications and Information Administration, a part of the U.S. Department of Commerce, issued a “request for comments on the benefits, challenges and potential roles for the government in fostering the advancement of the Internet of Things.”

    Two months later and the call for comment has been met in spades with more than 130 filings coming from a broad swath of telecom interests including carriers like AT&T, T-Mobile, Verizon and Vodafone; vendors including Nokia, Ericsson, Huawei and Samsung; and industry trade groups like the Wi-Fi Alliance, Wireless Infrastructure Association, the Open Connectivity Foundation and the GSMA.

    Here’s a full list of the respondents and their filings with NTIA. A review of some of the filings indicates a strong industry expectation that the rapid uptake of IoT will require global coordination and will likely create new markets while disrupting existing ones.

    Verizon representatives told NTIA: “To support this explosion of IoT devices, a robust and secure underlying communications network must serve as a foundation. That network requires both increased commercial spectrum and development of the underlying core infrastructure. We encourage all stakeholders to work together to ensure that these necessary building blocks for IoT development are available and accessible. To enable sufficient spectrum to power this new wave of connected innovation, private and public sectors must continue to cooperate, not only to develop more ways to effectively share spectrum, but also to provide federal users incentives to free up spectrum for commercial licensed and unlicensed use. As potentially billions of new IoT devices are deployed, they will drive data growth that – combined with the parallel growth in overall data usage by consumer devices – will require new commercial spectrum allocations to accommodate the unprecedented demands for more bandwidth. This includes spectrum necessary to support 5G, since 5G’s super-fast speeds and low latency will help facilitate new IoT use cases.”

    Ericsson commented: “In Ericsson’s view, 5G is the technology that will unleash the true potential of the Internet of Things. To support the IoT’s development, the government should unleash the resources that will ensure U.S. leadership in 5G by releasing more spectrum for commercial use. Through network slicing, 5G technology will allow a single infrastructure to meet the very different needs of Massive and Critical IoT devices – it will enable networks to handle the incredible increase in data from the billions of low energy, low data devices, while also providing very high reliability, availability and security for critical uses. We also encourage the government to support global standards and best practices and to allow industry to continue to innovate and coalesce around the most favorable IoT solutions.”

    And from the GSMA’s point of view: “The United States should forbear from regulating IoT and avoid reflexively extending legacy regulations designed for outdated technologies to the IoT…The U.S. government should support and promote industry alignment around interoperable, industry-led specifications and standards across the global IoT ecosystem…The U.S. government should promote the allocation of globally harmonized spectrum that can support IoT…The U.S. government should encourage industry to build trust into IoT devices. Existing laws and regulations, operating in tandem with self-regulatory regimes and best practices, will provide sufficient protection to consumers as the IoT develops…Finally, the U.S. government should engage on a bilateral and multilateral basis, as appropriate, to ensure that international IoT activities similarly encourage competition, investment, and innovation. Regulatory interference at this stage—from any source—could lead to fragmentation and impede innovation, inhibiting the IoT’s ability to reach its full potential to deliver benefits to consumers.”

  • IoT devices will overtake mobile by 2018 with Europe leading the way – Ericsson

    By Scott Bicheno            Telecoms.com

    The latest Ericsson Mobility Report forecasts such rapid growth in the number of global IoT devices that they will overtake mobile phones as the largest category of connected device by 2018. Ericsson reckons Western Europe will be the biggest growth driver for IoT devices, forecasting a 5x increase by 2021. This won’t necessarily be the result of a greater appetite for IoT by European consumers, however, with Ericsson saying directives such as eCall for cars and smart meters compelling the continent to increase its number of connected devices. “IoT is now accelerating as device costs fall and innovative applications emerge,” said Rima Qureshi, Chief Strategy Officer at Ericsson. “From 2020, commercial deployment of 5G networks will provide additional capabilities that are critical for IoT, such as network slicing and the capacity to connect exponentially more devices than is possible today.” While the majority of IoT devices will be connected via non-cellular means (presumably wired or wifi), cellular IoT devices are forecasts to be the fastest growing category. Ericsson reckons a major reason for that growth will be 3GPP standardization of cellular IoT technologies, by which it’s presumably referring to NB-IoT. Other notable findings from the latest report include the fact that global smartphone subscriptions are expected to overtake those of basic phones in Q3 of this year and that the use of cellular data for smartphone video has doubled among teens in the past year, in contrast to a significant fall in the amount of time they spend watching traditional TV. Additionally the first devices supporting 1 Gbps LTE download speeds are expected later this year. Lastly Ericsson used the report to bring attention to the need to harmonise 5G spectrum in the frequencies above those currently licensed for mobile but below the 24 GHz+ range that was addressed at WRC-15, including better accommodation for microwave backhaul. It said the 3.1-4.2 GHz range is considered essential for early deployments of 5G and offered the chart below to illustrate how un-harmonised the global microwave backhaul picture currently is.

  • Atari bringing back devices with Sigfox IoT agreement

    By Tim Skinner           Telecoms.com

    Retro gaming giant Atari will soon be entering the IoT arena following a partnership with Sigfox, the low power WAN provider. Famed for its trailblazing old-school computers and gaming consoles in the 1980s and 1990s, an announcement from Atari said it will soon be developing and launching consumer IoT services. While tangible details weren’t particularly forthcoming, and won’t be for the time being, Atari did hint at a move back to hardware having been primarily, if not solely, focused on software and gaming for the best part of the last 20 years. Atari said the initial product line will include offerings in areas such as home, pets, lifestyle and safety. By combining with Sigfox, Atari plans on developing a wide range of new products, from the very simple to the highly sophisticated, which users can track at any time. Sigfox says that by connecting to its network, products will benefit from an extended battery life and no need for paring or connectivity configuration. “By partnering together and using SIGFOX’s dedicated IoT connectivity, we are going to create amazing products with our brand,” said Fred Chesnais, Chief Executive Officer, Atari. “We look forward to our collaboration with SIGFOX and releasing new products to the mass market on a global scale.” It’s fair to assume Atari is targeting a move back into hardware and away from gaming, although more information will be released in due course. Atari says development of the new product line will begin in 2016.
