As we all know, 40GBASE-SR4 QSFP+ transceivers usually use a parallel multimode fiber (MMF) link to achieve 40G. It offers 4 independent transmit and receive channels, each capable of 10G operation for an aggregate data rate of 40G over 100 meters of OM3 MMF or 150 meters of OM4 MMF. However, for 40GBASE-LR4 QSFP+ transceivers, there are two kinds of links. One is coarse wavelength division multiplexing (CWDM) and the other is parallel single-mode fiber (PSM). What’s the difference between them? In this article, I will show their working principles to you respectively.40GBASE-LR4 CWDM QSFP+ TransceiverQSFP-40G-LR4The 40GBASE-LR4 CWDM QSFP+ transceiver, such as QSFP-40GE-LR4, is compliant to 40GBASE-LR4 of the IEEE P802.3ba standard. It contains a duplex LC connector for the optical interface. The maximum transmission distance of this transceiver is 10km. To minimize the optical dispersion in the long-haul system, single-mode fiber (SMF) has to be used. This transceiver converts 4 input..

Posted on Aug 18, 2016 by cozlink.com
Cisco System, Inc. established in 1984, is an international reputable company providing internet solutions, equipment and software products, whose products are mainly used to connect a computer network system, Cisco routers, switches and other equipment carries 80% of global Internet communications, of the new economy in the Silicon Valley legend. Over the past 20 years, Cisco has almost become synonymous with the Internet, network applications, productivity, Cisco have become the market leader in every area of its entry. The company is also specialized in producing transceiver modules include a well advanced and useful type of transceiver namely mini GBIC or SFP module.SFP is the abbreviation of Small Form Factor Pluggable referring to a compact small and hot-pluggable transceiver. Cisco SFP transceivers are designed to change the series electric signals to the serial optical signals for either telecommunication or data communication fields. The transceiver is usually working with a n..
What Condition is Required to Enable Layer 3 Switching?
Posted on Aug 22, 2016 by cozlink.com
Definition:Layer 3 switching is solely based on (destination) IP address stored in the header of IP datagram (see layer 4 switching later on this page for the difference). The difference between a layer 3 switch and a router is the way the device is making the routing decision. Traditionally, routers use microprocessors to make forwarding decisions in software, while the switch performs only hardware-based packet switching (by specialized ASIC with the help of content-addressable memory). However, some traditional routers can have advanced hardware functions as well in some of the higher-end models.What Condition Is Required to Enable Layer 3 Switching Quizlet:A network device that forwards traffic based on layer 3 information at very high speeds. Traditionally, routers, which inspect layer 3, were considerably slower than layer 2 switches. In order to increase routing speeds, many "cut-through" techniques were used, which perform an "inspect the first packet at layer 3 and send the re..
