Fiber Faults to Fixes: An IT Admin's Guide

- Fiber optics in the LAN, server room, and Data Center. We will explore single-mode and multimode
fiber cables and their types. A look at the revolution with MPO/MTP cables, connectors, and
transceivers.
We look at connectors, cables, and polish types typically found in LANs, server rooms and
Data Centers. Why polarity in fiber patch cables is so critical; the opposite of twisted-pair
copper patch cables. I will demonstrate why MPO connectors, cables, and transceivers bring a low-cost, high-fiber density revolution to LANs, server rooms, and Data Centers.

We need more of these episodes!! Can't wait Sir!!!
Thanks for the comments and come back for more!
Great video, and very educative.
Thanks for watching!
This is just amazing, I love your videos. I learn so much by watching them.
Thanks for watching and taking the time to comment!
Awesome information I love it! Thank you!
Glad it was helpful!
That was a real interesting video Mr V !
Thank you!
Thanks for comprehensive video. I really needed this info badly.
Glad it was helpful!
We need more and more ❤️❤️❤️
Lecture about optical fiber. #tnx sir ❤️❤️
Keep watching
Great Video like always
Glad you enjoyed
Across where from I live their a commercial building with a lot of office space. I walked around the building and notice a new installed ATT fiber box on the outside wall. So I just had to open it up , because that curiosity got the best of me . They had a new fiber line going under ground , so I followed it and it went up a pole about 400 feet away. Inside the box was a junction of 12 fiber wires going into a patch bay where it existed out around the building into a office space . Oh I was in heaven , when I saw the inside of this box
FTTH and coming slowly. Businesses have been getting fiber to their Demarc zone in their MDFs for years.
Thank you 😍
You're welcome 😊
These videos are really wonderful - educational and well presented.
Are there any optical tranceivers that operate in full-duplex mode over a single strand?
Yes: www.fiber-optic-transceiver-module.com/common-fiber-optic-transceiver-vs-bidi-fiber-optic-transceiver.html
I am right now troubleshooting a CNC machine (machining center) and the controller with components in electrical panel are talking with each other with fiber optic and right now data isn't seeing on the control when limit switches are triggered. However, haven't seen the same connector or cable like those shown in the video, it is way different. I assume the IT comm and industrial isn't the same at all. Too bad... 😔
Hopefully I can find some affordable equipment to see what's wrong
Industrial beats to it's own drum, they have many different standards than IT.
@@TechsavvyProductions here's the datasheet I found of the connector where the fiber is connected but not sure the part # of the cable itself. I wish to get a good tester and light source but I don't even know the type/name of the fiber cable end

Does fiber networks use modems like coax does ?
Great question! Fiber to the home FTTH, can use a type of "modem" (taking light and converting to video/ethernet), a better term would be a media converter. LAN to Data Center/ISP fiber uses a media converter taking ethernet to fiber, this is simplistic answer, it can be much more complex.
@@TechsavvyProductions when do you think most of the nation will switch to fiber networks ? Because i think its taking too long
Getting Local-City-State permits to dig or hang cable as well as the cost in man power to to rollout make it difficult and slow.
Wait a minute. If your school used OS1 -- _single-mode_ cable, there's no reason for it to have been obsolete in 15 years. The ST connectors would've fallen out of favor, but the fiber itself would be fine. If you _meant_ OM1 -- _multi-mode_ cable, then yeah, I'm surprised you got 15yrs out of it. (10G over that isn't going to do very well. For ~15m point-to-point, it's fine, but you'd be better off buying a newer OM3/4/5 cable instead. I say that looking at my bucket of 20yo OM1 cables -- some are more white/yellow as they've been bleached by years under florescent lights.)
jfbeam: you are sharper than a tack! It was OM1 not OS1 and yes we had ST connectors. They had to pull new fiber for our uplinks going from IDFs to MDFs. Thanks for the correction.... again!!!
How is it possible for multiple customers to share 1 line of fiber to the ISP?
One IP address has 32 bits (that's 32 possible 1 or 0 - Or 1 flash of light or none)...Inside the IP has data (thats more flashes of light)..There are other stuff too....this is just for one customer....for every customer to share one line to the ISP, thats like 1 million flashes of light in 1 second in one line. That's impossible. I can't fine an answer to this question anywhere.
Great Question: DOCSIS is the answer: see my video on ua-cam.com/video/FQAdGtMSf9U/v-deo.html
DOCSIS (Data Over Cable Service Interface Specification) enables multiple users to share a single coaxial or fiber-optic cable run for internet access. It does this through a combination of techniques:
Frequency Division Multiplexing (FDM): This is the most fundamental aspect of DOCSIS. Different channels on the cable are allocated for different purposes (e.g., one for downstream data, another for upstream data, and others for traditional TV services). Each channel operates at a different frequency, allowing multiple types of data to coexist on the same cable.
Time Division Multiple Access (TDMA) and/or Orthogonal Frequency-Division Multiple Access (OFDMA): For the upstream, DOCSIS typically uses TDMA, where different time slots are allocated to different users, effectively allowing them to take turns in sending data. This is common in earlier versions of DOCSIS (up to 3.0). DOCSIS 3.1 introduced OFDMA, which is more efficient as it allows simultaneous data transmission from multiple users by dividing the spectrum into smaller frequency blocks.
Dynamic Allocation of Bandwidth: The Cable Modem Termination System (CMTS) at the service provider's end can dynamically allocate bandwidth to different users based on demand. This is crucial for managing network congestion and ensuring fair access to resources.
Quality of Service (QoS) Management: DOCSIS can prioritize certain types of traffic (like VoIP or video streaming) to ensure a smooth user experience, even when the network is busy.
Encryption and Privacy: To ensure that users cannot access each other's data, DOCSIS includes encryption protocols (like BPI+ in DOCSIS 3.0).
These technologies collectively enable high-speed data transmission over the shared medium of coaxial or fiber-optic cables, accommodating many users with varying bandwidth needs while maintaining network stability and efficiency.
I'm NOT a fiber expert -- this is just an observation: At 12:33 you show a male and female "MPO connector". In life, mostly, a "male" plugs into a "female". This example does not appear to have the ability, nor any reason, to inter-connect as that is specifically designed for transceivers. Question: Are there male and female MPO transceivers? If so, why?
Craig, all transceivers that support MPO/MTP connectors are female. Patch cables are male to male and patch bays are female. This video did not cover the extensive topic of MPO/MTP but keep an eye on the channel as I am working on a future video on just this very comprehensive subject. I hope that will answer you great questions! Thanks for watching and for the comments.
