In telecommunication, an optical time domain reflectometer (OTDR) is an optoelectronic instrument used to characterize an optical fiber.

An OTDR injects a series of optical pulses into the fiber under test. It also extracts, from the same end of the fiber, light that is scattered back and reflected back from points in the fiber where the index of refraction changes. (This is equivalent to the way that an electronic TDR measures reflections caused by changes in the impedance of the cable under test.) The intensity of the return pulses is measured and integrated as a function of time, and is plotted as a function of fiber length.

An OTDR may be used for estimating the fiber’s length and overall attenuation, including splice and mated-connector losses.Is it done by our PC?how and what extra hardware
required?pl.answer me it will help me a lot

Hi,

I have a wireless ADSL modem and my line goes dead evey day at 9.36 PM.

Any ideas what is causing this. Even my provider doesn’t know the answer!

cu,

It has nothing to do with noise. I has been going on for 4 weeks now. Nothing changed so I don’t know what is happening.

100 Mbps Connection.
One Ethernet Port coming into my room.

I thought it was tx5000 something thousand. you can only get one signing up for a 5 year contract for $99. it looks like a little 1 inch by one inch by 3 inch box with a cat5 on one end and an rj22 on the other. you plug it into your router and you get a phone line, no software required. what is the name of this device/web site?

Ive restarted my Modem and my Router, but only my computer reaches the internet. I want to be able to play Xbox Live and be on the computer(internet) at the same time. My router is a NETGEAR Dual speed hub ds104, whenever i go to the network settings on xbox it tells me to restart my modem or router.

4.Nodes transmitting when it is their turn
5.Nodes transmitting after detecting that no other transmissions are taking place
6.A cable that connects end nodes to connectivity devices
7.A cable that connects connectivity devices
8.A cable type preferred for horizontal cabling
9.A cable type preferred for backbone cabling

a. Ethernet
b. Horizontal
c. Ring
d. 62.5/125 Fiber
h. Cat6 UTP
l. Backbone

Matching the terms up with the definition. Please help <3

also, tried google. Most were weirdly phrased O.o

I’m now in the 3rd semester of a B.Tech course in Electronics & Telecommunications Engineering.

Okay, so I got a 3-month gold subscription to Xbox Live and I’ve been told that i need a Cat5 cable, that I need a Cat6 cable, and that I need an ethernet cable, and that whichever one is right needs to be connected from a router to my Xbox 360.

Be first to Include a step-by-step guide of how to do it and what cord i need (Not from Xbox.com) and you get best answer!

I know that when you’re using the broadband on one computer, then another computer can’t be using it, but do you think there’s another way that I can get two computers to use one broadband at the same time? Somebody told me that I can possibly try using a router, but is it true? Please help. Thanks!

So I connect my Lnksys router, model WRT54G to the computer… It works perfectly, but then in a couple of days the internet on my computer stops working, while our wii and my son’s psp are still connected to the internet. Is there a solution to this problem, if so, it will be most appreciated.

I’m wondering if anyone knows of a way that I can utilize both ethernet and wifi at the same time so I can get a high bandwidth.
When I’m asking this I speak in regards to a single machine. There was a program I heard word of that did this for you.

How do i stop this from happening? Its really annoying especially while gaming

I have a netgear WGR614V9.

I cannot use xbox and pc on the internet at same time (even though they’re both connect via cat5 ethernet cables) Any Help?

Can any tech-inclined person help me with this problem?
OK, I have at&t dsl.
In the past, I had SBCYahoo! and all I had to do was click on the IE icon and Im online.
NOW, with att I have to:
1. right click on the 2 pcs icon (located on the bottom right of the taskbar – right next to the volume icon, near the time)
2. then I scroll up to “connect to a network”
3. a connect to a network window pops up and I click on Broadband connection – PPPoE connection
4. then the actual log in box comes up (it says connect broadband connection on top), I’ve saved my username and password or else it would be an even longer process…
5. finally, I click connect…
6. after a few seconds, It says successfully connected to broadband connection
seriously, I just want to click the “blue e” or Firefox icon. Isnt DSL supposed to be always on?
Once, I had a wireless network installed, is this the problem even though the router isn’t connected now?
How can I stay connected without having to do this each time?
