Undisclosed Vs Undisclosed Ethernet Challenge - Who Will Go The Distance?

Can or Can't?

Summary of events:*

The statements:

You cannot put 20 switches in place to extend a segment out to 2Km. - Undisclosed Manufacturer 1

You cannot get a single run of 300 meters to work. - Undisclosed 3

The challenge:

Tell you what, you setup a 300M 100Base-TX connection over any approved Category Cable and I'll setup 20 100Base-TX switches with 100M of Crap 5 cable between them. Undisclosed 3

The videos:

The 300M single cable over cat 5e video proof courtesy of Undisclosed Manufacturer 1:

First half of video proof for 20 switches for 20 feet from Undisclosed 3.

Timeline of video:

  • 0:00 20 Tenda 5.99 10/100 switches shown, bookended by Dlink POEs switch (left) and Dlink router (right).
  • 0:04 Monitor shown with active ping and video from Axis camera powered by Dlink POE switch. (red cable)
  • 0:11 Axis camera (black) shown on middle of table (red cable)
  • 0:15 Axis camera obscured by disembodied hand, low latency results shown on monitor.
  • 0:24 Closeup of Dlink router and then pan of front Tenda lights
  • 0:32 Closeup of Dlink POE, then following red cable to Axis P3367 5MP camera
  • 0:40 Top view of back switch connections
  • 0:50 View of Dlink router connection to computer (yellow cable)
  • 1:00 Back view of switch connections
  • 1:20 System overview page of Axis camera showing 192.168.0.101 address acquired thru DHCP without problem as well as bitrate of 86 Mbps. (MJPEG)
  • 1:28 Series of random power pulls and reconnections demonstrating robustness of the Tenda fabric
  • 2:28 Switch lights drive by and final overview.

Notes: Total of 23 ethernet interfaces involved from camera to computer. Total switch cost: < $120 for 100 ports, 62 usable ports = < $2 per port cost. The switch comes in a ruggedized version for $3 more "Tough on the outside, Tenda on the inside".

Patch cables are 1 foot.

Assuming there are no questions to this test, cables will be changed first to 150 ft, then 300 ft for the 2km final test.
