Understanding Cisco GBIC and SFP ModulesCisco GBIC (GigaStack Gigabit Interface Converter) is a general-purpose, low-cost Gigabit Ethernet stacking module provides high-speed connectivity between the Cisco switches, either the establishment of high-density port stacking, but also with the server or thousandsmegabit connection to the backone for fast Ethernet to Gigabit Ethernet transition, providing a low-cost, high-performance alternative. In addition, by means of the optical fiber, but also with remote high-speed backone network connection. GBIC module is divided into two categories, one is the ordinary cascade using GBIC module, and another is stacked special GBIC module.Cascading GBIC moduleCascade using GBIC module is divided into four kinds:1000Base-T GBIC module, suitable for five or six super twisted pair, the maximum transmission distance of 100 meters.1000Base-SX GBIC module for multimode fiber (MMF), the maximum transmission distance of 500 meters.1000Base-LX/LH GBIC module ..
Three Factors to Consider for Smooth Migration to 40G
Posted on Aug 24, 2016 by cozlink.com
10GbE (Gigabit Ethernet) is no longer enough for the increasing need for high speed transmission with applications like Big Data, Cloud and Internet of Things being introduced in a variety of industries. Transmission network migration to 40/100G has already been the industry consensus. As the cost for 100G is far beyond what most companies can afford and the technology for 100G is still not mature, there is still a gap to reach the transmission speed of 100 Gb/s. However, to satisfy the current need for data rate, 40G could be a better and more economic solution. Currently the servers in many data centers are ready to carry the transmission of 40 Gb/s. The core technologies of 40G are gradually mature. In addition, more manufacturers are battling for the 40G market, which drives down the 40G deployment price.Unlike 1G migrating to 10G, 10G migration to 40G get across a much larger span in terms of not only transmission data rate but also technologies. Thus, the deployment of 40G migrat..
Definition1000 BASE transceivers are kind of small form-factor pluggable (SFP) transceivers. They are used for both telecommunication and data communications applications.1000 BASE transceivers links your switches and routers to the network. The hot-swappable input/output device plugs into a Gigabit Ethernet port or slot.HistoryEthernet was the result of the research done at Xerox PARC in the early 1970s. Ethernet later evolved into a widely implemented physical and link layer protocol. Fast Ethernet increased speed from 10 to 100 megabits per second (Mbit/s). Gigabit Ethernet was the next iteration, increasing the speed to 1000 Mbit/s. The initial standard for Gigabit Ethernet was produced by the IEEE in June 1998 as IEEE 802.3z, and required optical fiber. 802.3z is commonly referred to as 1000BASE and launches 1000 BASE transceivers.VarietiesThere are five physical layer standards for Gigabit Ethernet using optical fiber (1000BASE-X), twisted pair cable (1000BASE-T), or shielded bal..
