Here is tear-down of old Zyxel ES-108 10/100Mbit/s Ethernet switch. I had one on my network for many years, but one day it stopped worked and started making whining noise. Look inside. Closer look to details. Main Ethernet switch chip is ADM6999 from ADMtek (now part of Infineon). In addition to it line transformers and power →
How low can Ethernet switches prices go? In small unmanaged 8 port 10/100M 5 or 8 port switches typical price is around 15-25 Euros (around 2-3 Euros per port). But there are even cheaper Ethernet switches. Netwjork Tenda S108 SOHO kytkin/switch jossa 8 porttia is a very cheap 8 port 10/100M switch that costs only →
Cracking open a 24-port switch so you don’t have to posting at Hackaday point to an article Tear-Down of an HP ProCurve 2824 Ethernet Switch that is worth to check out for everybody interested in device tear-downs and Ethernet. Tear-Down of an HP ProCurve 2824 Ethernet Switch article shows you the technology inside a managed →
Ethernet switches are the ubiquitous building block of any intelligent network. Ethernet technology is deployed in virtually every organization’s data center. Wide Area Networking (WAN) and Metropolitan Area Networking (MAN) providers need to provide their customers with Ethernet services. Ethernet has also become the de facto networking technology in industrial automation even in mission-critical local →
LAN iSilencer Audiophile Ethernet Dongle Claims to ‘Quiet Your Network’ article says that at ‘just’ $100, it seems like a “bargain” compared to some audiophile Ethernet cables. iFi-Audio has released the LAN iSilencer, an audiophile accessory which aims to “quiet your network.” According to the Ethernet dongle designers in Japan, this product removes digital signal →
One day I came across a device called “Ethernet Network Isolator” and started to wonder why we would need such device as standard Ethernet system that uses twisted pair cable and RJ-45 connectors is already isolated from both ends of the cable (isolation transformers that can withstand 1500V). When the network connections made with unshielded →
Passive Etherner hub is special device I have seen in use in 1990′s. Nowadays there is no real use for Passive Ethernet hub, because it will not work with modern Ethernet standards (it only worked with 10BASE-T). Actually using Ethernet hub is nowadays past days as they have been for a long time replaced with →
Venerable Ethernet provides the backbone of the internet. Ethernet has risen to complete dominance for local area networks over its forty years of existence. The first Ethernet experimentals versions started in 1972 (patented 1978). The commercialization of Ethernet started in 1980′s. At first Ethernet technology remained primarily focused on connecting up systems within a single →
Nowadays it is possible to buy passive and active device to run Ethernet over Coax – some products support data transfer over larger distances then you can get on regular Cat5. The passive converters are typically limited to 100 Mbps maximum speeds up to 100-200 meters distance maximum. If you need faster speed or longer →
Ethernet co-inventor David Boggs dies at 71 https://www.engadget.com/ethernet-co-inventor-david-boggs-dies-at-71-110524422.html Pioneering Xerox PARC computer researcher David Boggs has died at 71, The New York Times has reported. Boggs was best known for co-inventing the Ethernet with Bob Metcalfe. Boggs joined the team in 1973, and started working with fellow researcher Bob Metcalfe on a system to send →
