What people are saying about Pockethernet

"I’ve been waiting with anticipation for my Pockethernet for a while. Now it’s arrived I am very happy. A solid device, handy case and a good, simple to use but comprehensive App. This device is going to make my life so much easier next time I suspect a network problem on a job. No more guessing and trial and error by swapping out cables until maybe it works again. And no more having to take a laptop into small spaces and hoping it doesn't fall behind the switch rack.

Review by Benedick Miller

...I really would’ve had no idea where the fault was located with my previous cable tester. However, after just a couple of weeks of ownership, today my new Pockethernet has really shown its value – locating the distance of the fault led me to a very tight corner of a roof space which otherwise would not have been obvious...

Review by Richard Mahoney, StrataNet Limited

...it’s a luxury to have such a nice piece of equipment for any kind of potential issues with my network at home.

Review by Brian Moses

...Pockethernet provides a best of all worlds solution: good existing functionality, a roadmap with plenty of new features, ease of upgrade, and a price that really can’t be beat by any other cable tester on the market.

All features

  • Wiremap including shield

    Check whether pins on RJ45 jacks have been entered in the correct order. Pockethernet also tests the shield for continuity.

  • TDR

    Advanced cable testing with only one end connected to Pockethernet. Determine how long a cable is and if it contains any short circuits, split pairs or bad terminations. Pockethernet also detects if a cable is connected to a switched-off computer or switch.

  • Graphical TDR

    Generate a graph of signal reflections throughout the entire cable length. Here you can view the length of connected cables and any imperfections they may have (such as extenders or patch panels).

  • VLAN support

    Set the VLAN tags, PCP and DEI for outgoing DNS, DHCP, HTTP and Ping requests. View tagged and untagged traffic with the traffic monitor.

  • Network discovery (CDP, LLDP)

    View the content of CDP and LLDP messages to identify network ports more easily. If the switch port supports it, you can instantly view the connected chassis and port ID as well as the native VLAN.

  • Voltage detection

    Find out if any pairs have a phone line or passive PoE connected to them. This allows you to detect services and to protect your network equipment.

  • PoE supply detection

    Measure the presence and voltage of Power over Ethernet to ensure a sufficient power supply for your PoE devices.

  • Cable toner with customizable tones

    Determine the location of cables in a wall and identify single cables in batches or at patch panels. You can set different tones and even control their volume to keep signals separate.

  • Bit error rate test (10/100/1000)

    Real-world cable quality measurement at gigabit speeds. Measure packet length, payload and configure the number of test packets.

  • Port blinker

    Let Pockethernet toggle the Link LED on switches and routers to easily find the cable you are looking for. Set the link speed to toggle a change of color for the port LED.

  • Link speed and duplex identification (10/100/1000)

    Find out the Ethernet capabilities of that unused port you're wondering about and rule out duplex conflicts.

  • Link establishment test (10/100/1000)

    Determine whether a link can be established at different speeds and make sure the wiring is up to date for gigabit.

  • DHCP, DNS, Ping, HTTP tests (10/100)

    Test the network connection to see if you are able to get an IP address on a port, and connect to internal servers or the Internet.

  • Traffic detection (10/100)

    View which other devices are reachable on a specific port, as well as the type and amount of traffic that is being directed there.

  • Generate PDF reports

    Keep a detailed, up-to-date database and log of your work just by noting locations and port IDs.

  • Export your results

    Email reports for your own records, or share them through a phone’s OS's native share menu with the press of a button. No more lost reports, tedious downloads from the device or manual editing.

FAQ - Technical

  • How do I reset Pockethernet?
    • There's a reset function in the device: Press the power button for 10 seconds, and then connect the USB plug.
  • Which wiremap adapters are compatible with Pockethernet?
    • Pockethernet is delivered with its own adapter which also serves as a loopback terminator for BER tests.
  • How does Pockethernet do single-ended length measurement and fault locating?
    • Through the use of TDR (time-domain reflectometry).
  • How close does my phone need to be to Pockethernet to work?
    • Under normal conditions, Pockethernet should be kept within 10 meters of your phone.
  • How accurate is the TDR test?
    • After calibration, 2 meters or 5%, whichever is greater.
  • Does Pockethernet come with a tone probe?
    • No, Pockethernet does not come with a tone probe. A huge variety of them are available for between $20 and $200. The higher-end probes are usually more sensitive and do better 50/60Hz humming rejection. Any analog tone probe should work with Pockethernet. In case you’re not sure, just ask us at: info[at]pockethernet.com and we’ll let you know. .
  • Does Pockethernet support IntelliTone from Fluke?
    • IntelliTone is patented by Fluke, so we can't support it unfortunately. (Though the hardware would be capable of that)
  • Can I connect Pockethernet to a phoneline?
    • No. Technically the device shouldn't get damaged by it, but it's still not allowed since it doesn't have protection against lightning strikes or similar high-voltage events that can happen on a phone line.
  • Can Pockethernet detect which VLAN a port is connected to?
    • If the port is in access/untagged mode, the VLAN tags are removed by the switch before sending out the packets, hence they are not detectable by the device. If configured for the port, Pockethernet can receive CDP or LLDP information, which usually includes the native VLAN ID. If the port is in trunk/tagged mode, or is an access port also carrying tagged packets, you can use the traffic monitor feature to see the VLAN IDs of frames that are sent over the link. In this case however, you can only see the available VLANs on which there is traffic at the time of measurement.
  • Can I use the toner on a live wire that has a switch on the other end?
    • You can use the toner on a live wire, neither Pockethernet nor the other device should be damaged as the signal is just a couple of volts and current limited. The only drawback would be that the sound level will be much lower as the Ethernet transformer and the terminations ground the signal. Also, if it's a shielded cable and the connector on the other end gets grounded by the remote device, it may completely shield the signal.
  • Can I use the wiremap/loopback terminator as an RJ45 Coupler?
    • No, you can't.
  • For which tests do I need the Pockethernet wiremap/loopback terminator?
    • The Wiremap side of the terminator is used for the *drum roll* wiremap test. The Loopback side is used for the BER test.
  • Can Pockethernet also do cable certification?
    • No. Pockethernet is not a "cable certification" device, but performs cable qualification and verification.
  • Can Pockethernet be used to test IP cameras?
    • If you use Pockethernet instead of the camera it's possible to: check the cabling to the camera, test if there's PoE supplied on that cable, check if a network connection can be established on the cable, with specific VLAN settings and ping targets. If the camera is already on the network, it can be pinged from another ethernet port

      What Pockethernet can't do is to connect to the camera and get the picture, change settings, etc. However, these would be software features that can be added in future. (if you are very interested in that, please write us about it via info AT pockethernet.com)
