APC connectors wont work like that. Both ends MUST be apc- polished if u want to use it. U also did not mention, that you can use one fiber to send AND receive data. This is handy for "ftth" (fiber to the home) applications, because it cuts need of fibers to half. + Less patch cables, switches etc...

This is by far the most exciting and informative technical video for a non-technical person such as myself...Thanks a million Kevin...and when I say Non-Technical, I mean i'm frightfully deficient in my comprehension of technical terms. Off to get any book I can find on this subject...any recommendations? We found unused MMF fibre optics from the 90's in our community 'off grid' and we just want to understand it enough to utilize its application for Agriculture..farming is the mainstay of our rural economy... Thanks a million for this...i am quite certain it will help us identify and communicate better what we want to achieve

Hi Kevin, that was very helpful. May I ask a question about the length of the fiber cables? I'm using a 1GB media converter (Single mode) and the FSP module states that it can go up to 20Km. If I use a 30 M single mode cable, will that harm the converters? I saw a video saying that the wire length should match the distance that the converters can handle.

Mr Wallace, from visual explanation of 2 connectors touching in APC scenario, it looks like we should use APC on one end and UPC on the other end. But this is not true. That gap between APC and UPC connectors actually causes a lot of power loss. You should alwaus use UPC vs. UPC and APC vs. APC.

How the laser attain different angles in MMF? Do we have many laser diodes kept at different angles? If there is only one diode , how can light travel in different directions unless the diodes angle is changed physically for each light?

@VanTekConsulting 2 жыл бұрын

Fiber has a "Numerical Aperture" (Cone of Acceptance), this is how the core accepts the light. In MM fiber (Depending on OM1-OM5) type use LED or VSCEL lasers. These are stubbed or non-contact, so think of how the beam of a flashlight spreads. The further you are from the surface the larger the spread. Not quite this dramatic with a laser or diode but then again, we're dealing with nanometers (one billionth of a meter). Hope this helps.

Is there such a thing as direct bury fiber and do fiber cables have a fire rating?

@VanTekConsulting 2 жыл бұрын

Yes on the direct bury cable. A large share of fiber in the US is direct buried. Fire rating, Yes. National Electric Code is the governing body. Cable is rated and marked, if no marking it is considered General Purpose. A cable will be marked OFXX (Optcal Fiber), XXNX or XXCX (Non-Conductive or Conductive (shielded, non-shielded)), then XXXG,R or P (General, Riser or Plenum). A rating would look like OFNR (Optical Fiber, Non-Conductive, Riser), OFCP (Optical Fiber, Conductive, Plenum). Hope this helps.

Thank you for this video. Can you explain me please what does λ symbol on power meter means? I know that is wave length in physics, but how that affect on fiber optic cable loss measurement?

@VanTekConsulting 2 жыл бұрын

Correct λ is the wavelength i.e. 850 nm or 1300 nm for MM. The effect on loss/attenuation is that the shorter the wavelength, the higher the frequency, the more attenuation (loss over distance). Think of it this way, a subwoofer in a car. You can hear the lows but can't hear the highs. Higher frequency always attenuates faster than lower frequencies. Hope this helps.

Time Stamp 8:32 is really not accurate, and misleading. The idea in the graphic is that an APC (Angled Ultra-polished Physical Contact) connector is connected to a Flat Physical Contact connector is absolutely incorrect. For new folks watching this DON'T EVER DO THIS! APC to APC Only. IF this were to be done, there would be high loss and a HUGE Fresnel reflection. It would also most likely damage the flat connector causing further issues. I understand the intended principle trying to be explained, but this a terrible example.
