Very nice summary info. Appreciate the time and effort spent producing this video.
There is one correction needed that I'd like to highlight though, re testing.
From the 16:24 mark, Single reference cable Referencing is stated to be a "quick and dirty" less accurate method vs using the double reference cable method.
The opposite is actually the case.
Including the mated connector pair (that we end up with using the double cable method) in the referencing actually results in the loss of that/a connector pair being excluded from the final loss calculation/measurement for the cable/link under test (which when in normal operation, will have 2 mated connector pairs existing. One at each end.)
Therefore:
Single cable referencing - For patch cable testing and installed link testing. The preferred referencing method.
Double/Two cable referencing - Acceptable, for installed link testing, but reports less loss measured than what a normal operational link would have.
That total loss measured would be one mated connector pair of loss LESS than actual total loss existing.
Whichever method used however, it is imperative that it be documented along with the test results in order to be meaningful to future test technicians.
Google FOA loss testing for further details.
Love the feedback and comments, they are always welcomed!
SO MUCH ! value & information in this awesome video !
Thank you for your support!
Awesome info, getting involved in FTTH. Done a lot of splicing / butt splicing / testing 864/144, etc. thank you
Thanks for watching!
@23:28 I recall back when I did my FO accreditation here in Australia, my facilitator warned you dont always know if the fibre is lit as not all transmissions are visible, treat all fibres as energised
He also warned that anyone caught looking in the end of a fibre would be failed on the spot regardless of it that fibre is lit or not...
As always, love your videos Lowell, keep em coming!
There are some WAN transceivers that can have high power lasers but most of them are safe, again no one recommends staring into any laser at any power level. Thanks for the comment and for watching!
While a good practice -- and in a teaching setting, a proper approach -- 1300+ isn't visible, and the laser light isn't strong enough to cause cell damage. (i.e. it won't burn your skin, or slice a finger off.) Plus, 9micron isn't a lot of light -- it would be hard to see even if it were visible. Your VFI works because it's firing light into the entire 125micron fiber (core _and_ cladding) If you work with FO a lot, one should take all available precautions, but an occasional flash won't hurt you. Even ER and ZR optics aren't "death ray" lasers -- their range comes more from receiver sensitivity than laser power.
(Note: 850nm is technically not visible either, but there's often enough red for us to see it. I've actually seen some 850nm MM emitters [LED] that a 1310nm receiver could see; let's just say MM "lasers" aren't very precise.)
This video is a gem
Thanks for watching!
wow salute sir! very educational u have my sub - from the Philippines :D
Salamat sa suporta
Awesome video 👍 keep post more
Thanks for watching!
Thanks
Welcome
Error correction doesn't "kick in". It's either on and codes are being sent with every frame to fix whatever minor errors _may_ be occurring, or it's off and any errors cause frame loss. FEC does consume space, so overall usable throughput is lower, but in systems where FEC is part of the design, it's already part of the throughput numbers. (it's not supported everywhere. and until 802.3by it looks like a vendor specific mess.)
jfbeam: love the comment and your point on FEC, we welcome feedback and correction on any topic or concept we produce. We appreciate you on the channel!
Where must the cross over (TX-RX and RX-TX) be done in a fiber optic installation? Is it in the patch cords or behind the parch panels?
Most cables by default are cross-over.
Can i ask,how to deploy ftth internet together with cable television in one network using using diff.equipment ex. is olt,mikrotik???do you have a tutorial video for basic,or anybody help me to know my needs..,
Interesting question, I am not sure but I will take a look and if I find some information I will post.
In Daytona Beach, the cell towers are connected by underground fiber cables
John, thanks for watching and your comment!
Why should we use 1310 and 1510 and not 1490 for testing?
Ideally you would test single mode links at both 1310 and 1550 nm wavelengths. Generally speaking, the 1310 nm wavelength is more sensitive to alignment problems (i.e. loss events), and the 1550 nm wavelength is more sensitive to issues caused by bends and cracks in the fiber link under test. Comparing the 1310 nm wavelength loss with the 1550 nm wavelength loss can indicate a bend or crack is present if there is more loss at the 1550 nm wavelength than the 1310 nm wavelength.

yes!
What lvl is this corse. Btec 3.. or 4..
I am not sure if you are referring to Pearson BTEC International Levels. Thanks for watching!
16:07 -30dBm = 10µW, 0dBm = 1000µW = 1mW
16:19 +20dBm = 100mW (don't look into laser with remaining eye!)
