  by www.fiber-mart.com Media converter and network switch are both widely used in today’s high speed network applications. In some scenes, one can used to replace another one. Then, which one should I choose for my network? What is the difference between media converter and network switch? This post will cover the knowledge of media converter and network switch, and explain the difference between them.   1.What is Media Converter? Media converter is a very simple networking device that used to convert electrical signal utilized in copper cable to light signal for fiber optic cabling and vice versa. It is essential to have the fiber optic connectivity if the distance between two network devices is greater than the copper cabling’s transmission distance.

  by www.fiber-mart.com HDMI optical cables have been an effective alternative to HDMI copper cables for a few years. However, what exactly is the difference between them? One thing hard to ignore is the difference of material under the coating, in which there is fiber for HDMI optical cable and copper for HDMI copper cable. Taking reference from the DAC and AOC, there are facts such as the transmission of fiber is faster and the signals on fiber are more reliable.   In order to better comprehend the HDMI optical cable, the meaning of HDMI is the first thing we should get to know. HDMI stands for High Definition Multimedia Interface, featuring the extraordinary capability of signal transmission. For example, the latest specification HDMI 2.0, which was released in 2015, supports a maximum bandwidth of 18 Gb/s. HDMI interface has become a mainstream solution for transmitting uncompressed video data and compressed or uncompressed digital audio data from an HDMI-compliant source ...

  by www.fiber-mart.com We are going to talk about three types of appliance that are usually confusing the users, which are the matrix, switch, splitter. Most of you might have heard of the switch before while the switch we are talking about is not exactly same as the conventional switch. As the HDMI standard is getting more and more popular, in addition to HDMI copper cable, there are HDMI transceiver, AOC coming up these years. So far, we even have something more comprehensive which are the matrix, switch, and splitter. They could greatly expand the use of HDMI products by controlling the signal flow.   1.What is the switch of HDMI? The switch usually has various ports on its patch panel, usually, there are several HDMI input ports and a HDMI output port. With a tiny box like the image below, your monitor in the living room can display signal sourced by the case, PlayStation 4, etc. It’s like multiple signals can be sent to a monitor by the switch although the monitor can on...

  by www.fiber-mart.com PoE (Power over Ethernet) is a mature technology being widely applied in communication industry nowadays, it aims to solve the trouble of power supply because devices without PoE basically need a power cord other than another cord to transmit data. There are various Power Source Equipment (PSE) like PoE switch, PoE injector, PoE media converter can be used to achieve PoE network. Here is some basic knowledge about them.   PoE Technology Overview   The IEEE standards for PoE require category 5 cable or better for high power levels but allow using category 3 cable if less power is required. Power is supplied in common mode over two or more of the differential pairs of wires found in the Ethernet cables and comes from a power supply within a PoE-enabled networking device such as an Ethernet switch or can be injected into a cable run with a midspan power supply. A midspan power supply, also known as a PoE power injector, is an additional PoE power sour...

  by www.fiber-mart.com The products that adopt a certain standard called HDMI is getting bigger. Meanwhile, the demand for better solutions of public display and media transmission is unprecedentedly increasing. HDMI 2.0 is the most popular standard for now, along with HDMI 1.3 and HDMI 1.4. When it comes to the product itself, it can be classified based on how far they can transmit the signal. Here is a category provided by 10Gtek which is a manufacturer in Shenzhen to give us a glimpse of HDMI related products.   1. Short Range (0-10 meters) When the need for distance is under 10 meters, HDMI copper cable which is quite common now in your room is the only product that you can expect. As a copper cable, it can transfer electricity as well though it might limit the transmission speed of the signal. Currently, there are HDMI 1.3, 1.4 and 2.0 of HDMI copper cable can be bought in stores.   2. Medium Range (10-100 meters) For the medium range of around 10 to 100 meters. The...

  by www.fiber-mart.com With the sharp increased of Ethernet data processing in the applicable field of cloud computing, super computer, IDC and enterprise data center etc., we are now seeing large demand of I/O. To keep pace with network development and meet the demand, transmission data rates have upgraded from 1Gb/s to 10Gb/s. To accomplish 10GBASE Ethernet network, there are different existing solutions to the access including DAC(Direct Attach Cable) and 10GBASE-T SFP+ transceiver. Each of which comes with distinguished benefits and shortages from each other. But the 10G SFP+ copper transceiver achieves the connectivity with power saving by employing CAT6a/7 cabling structure, and it has a advantage of much flexible usage.   10GBASE-T SFP+ Copper Transceiver Overview 10GBASE-T, know as the standard of IEEE802.an, which was released in 2006 support 10Gbps Ethernet network over un-shielded or shielded twinax cables(CAT6/CAT7) with a distance of up to 30m by CAT6 copper.

  by www.fiber-mart.com What’s SFP+ DAC Twinax Cable? 10G SFP+ DAC is established on copper inter-connectivity by using a twinax cable assembly to connect with SFP+ housing. It substitutes the costly optical transceiver required in the Ethernet deployment and tremendously decreases the power consumption, latency and installation time. Based on above, it’s the prior choice of SFP+ DAC to adapt to modern 10G network with requirement of short-distance and high-speed. With a limited transmitted length of up to 12m, SPF+ DAC is very much general used in intra-rack and inter-rack connections. such as interconnected with top-of-rack switches and servers, as well as between storage devices in one rack or neighboring racks.   Active or Passive? Generally speaking, SFP+ DAC active cable is much expensive than SFP+ DAC passive cable. This is because of it needs DC power to integrate signal processing circuitry into the built-in connectors of SFP+ DAC active cable with a length link of up...

  by www.fiber-mart.com 10GBASE-T, or IEEE 802.3an-2006, is a standard released in 2006 to provide 10Gbit/s connections over unshielded or shielded twisted pair cables, with distances up to 30 meters (98 ft) with RJ45 connectors on an electrical transceiver (or copper transceiver). It’s backward-compatible with existing 1GbE (1 Gigabit Ethernet) networks, meaning that it can be deployed based on existing 1GbE switch infrastructures in data centers that are cabled with CAT6 and CAT6A (or above) cabling. 10GBASE-T is a cabling solution of 10GbE, the other 10GbE cabling solutions include SFP+ fiber (10G-SR,10G-LR,10G-LRM, etc.), SFP+ Direct Attach Cable (DAC), SFP+ Active Optical Cable (AOC).   The most outstanding difference between optical transceivers and electrical transceivers is the transport media they use, as a result, optical transceivers should be linked with optical fiber and electrical transceivers should be linked with networking cables such as CAT6.   Generally...

  by www.fiber-mart.com 1.How to connect 10 Gigabit Ethernet CNA/NIC Intel X550 with 10GbE switches? Answer: Intel X550 is a kind of 10GbE converged network adapter, with RJ-45 ports. But most of 10GbE switches are with SFP+ ports. Port RJ-45 and port SFP+ can’t be linked directly. That is, we need a port converter to convert SFP+ to RJ-45. 10G copper transceiver is that kind of “converter”. Deploying 10GBASE-T transceiver and CAT.6A cable, the interconnection of 10GbE NICs with RJ-45 port and 10GbE switches with SFP+ port can be realized.   2.What is the maximum transmission distance of 10Gb/s copper transceiver? A: 30 meters, by CAT.6A cable.   3.Is it possible to use CAT.5E cable to link with 10GBASE-T? A: No. The standard bandwidth of CAT.5E is 100MHz, and CAT.5E is designed to transmit signals below 90M. 10 Gigabit signal transmission requires a CAT.6A patch cable.   4.Is 10GBASE-T pluggable? A: Yes. Please note that frequent plugging and unplugging may affect t...
