My step son does this type of work in and around Atlanta. He's tried to explain to me how it's done, so thank you for showing this. love all of your vids.

Thank you for sharing your expertise and a piece of your work life. Regards, Dave

Lovely to watch an expert at work - thank you for this very careful and detailed demonstration of how to properly make a mechanical connection. Here in France where they are doing a mass deployment of fibre, some individuals have been complaining about poor or non-existent connectivity, and watching how you carefully perform each step, it will be easy to complain about possible errors in the set-up if necessary. Many thanks.

Very interesting. Friend of mine years ago (circa 1999) mentioned having to get certified for working with fiber optic. Lots of stuff about polishing the end of the cable and what not. Didn't go much into it only that it was pretty involved. Guessing things have evolved quite a bit since then. Thanks for sharing this with us, definitely was always curious about it.

Cleaving is what cuts the fiber at the correct angle to make the connection. It is all about cleaning the strand. Fusion splicers align the ends and use an electric arc to bond the pieces perfectly.

0:15 love bmw e36 :) I still have it. mine is form 1993 :) btw. thank you for this video. I didn't realise that fiber has such a complicated connections

Is nice to learn from people that know what they’re doing great video 👍

That's an interesting process, keeping the termination to a known and reliable quality. I've only seen the non glass fiber used in pretty lamps and very low speed data use. My connection is a coaxial cable type, not fast but good enough for my needs. Kevlar i've seen in drive belts for motorcycles, it's not cheap but long lasting and tough.

I saw your using SC ends. I noticed around here most stuff is coming with LC. the video display job we did in Tennessee at Jefferson high school we used a fiber patch panel and went to ST instead of SC or LC. And just used a simple off the shelf ST to LC for the SFP blades. the fiber we pulled was 6-strand, and I only needed a pair for the media converter so it left some spares in case something got damaged. Lucky because 1 of the fibers was dead, and a 2nd fiber was in a "degraded" state according to the tester. Neat stuff. We hired a company to come out and terminate/splice the fiber.

Man that looks easy. 20 years or so ago, after cleaving, you had to epoxy the fibre into the connector and then carefully polish the end of it; at least on the course that I went on in '96.

This is an optisnap system for end termination only. All the other strands are are fused with an electric arc that melts the strands together.

Very interesting video. I have seen Corning tools before but never seen how they work. I use a 3M system, and the crimping tool is way less impressive, but my Japanese cleaved looks more like a high precision mechanical assembly. When I was teached about fiber optics, we were given a good trick to limit the risk with shards of loose parts: we generally use some stickers like printers address forms to get a "receiving" surface to get rid of all loose parts and cleaved fiber parts: once the job is done, you have just to fold the sticker and dispose in a special container. Mono-mode fibers core diameter is only 9 um, Multi-Mode is generally 50 um, always finer than hairs and as you said, always a high risk to manage, as eye exposition to laser rays used as test tools.

Yes the guys that splice fiber all day stick some stickers out to grab all the shards of glass. In my line I am doing 3 tops per job. Termination at the demark and then sometimes a clear curve run. Many times I wll just use a pre-connector run as it comes in 10 20 and 30m (30 60 90 feet) lengths, and just run that into the house. Invisalight is also used in apartments, but I haven't been trained on that yet. That is a different crew that deals with that stuff. Those guys are the low paid crew that works in apartments and such.

In my part of the US we have had fiber to the home for around 12 years now through Verizon. Around here they don't even bother custom cutting the fiber drop from the pole they just use pre terminated lengths and coil up the excess cable in a purpose built cavity at the back of the ONT. The fiber drop from the pole goes directly into an Optical Network Terminal or ONT most are mounted outdoors and are powered by a Battery Backup Unit (to provide phone service in the event of a power outage) and a power adapter both mounted indoors on the opposite wall. The ONT provides TV (over coax), Phone (over copper), and Internet (to a router either over RG6 Coax using Moca or Cat 5 Ethernet). If you have an Internet package 75 Mbps or under they usually use coax (since I believe Moca only supports speeds up to 100 Mbps) if you have a faster package they are forced to install an ethernet cable from the ONT indoors to your router.

It is a new moca ont that feeds over coax to the gateway and is powered over coax. This isn't on the market yet as it was developed in house. Undergoing environmental testing and should be rolled out soon which will make these installs easier.

yes our isp sell optical fibre then the cable going into the router is coaxial, so there must be a converter somewhere, or its just cable and selling as optical fibre

Very interesting video, always nice to see how things are done before being connected to equipment. But I'm a little confused as there is only one fibre. We've got two fibre wires going into our fibre switch at home, one for TX and one for RX. How does it work with just one fibre?

Christian Kaderud Frequency multiplexing. One wavelength for the multiplexed down stream. All ont on the multiplex see all the data and pick off only what is addressed to the ont. The main fiber coming out of the olt at the central office is optically split 32 ways and feeds 32 customers. The ont then talks back on a different wavelength of light. If we were talking visible spectrum the downlink would be blue light the uplink red. Each ont in the customer premise only talks during its time slice. This is called time division multiplexing. Some systems use 2 fibers. One for each direction but newer systems do it with a single strand.

hi wish i had fibre to premises here in uk but still uses some copper up to house from box

Even though the piece of fiber, it sounds similar to the Cacti needle, whenever somebody got pricked the tiny little spike from the cactus, then it can get to the pores, tissue, or any kinds of veins that can travel to the body regions, and it can be dangerous.

You should look up Cleerline SSF. It puts the old Unicam connectors like that to shame. Can be re used over and over. If you mess up, no problem. Also their fiber is safe when cut and has an amazing bend radius. Also cheaper. We recently had a training on it and were pretty impressed.

I worked for lucent technologies a pretty long time ago and we learned how to splice fiber but back then we used a drop of some type of glue on the tip then we had to use this puck type thing to sand the tip and then we used a microscope to see if we damaged the tip😬

Hey Dave, Is there such a thing as a Fiber Optic splitter or are they all home runs only? Second question,why such a long piece of white fiber out of the sheath? Is it for easy connection to a device without the strain?

@12voltvids

6 жыл бұрын

Yes the fiber is split. The correct term is GPON. That is an acronym for "Gigabit Passive Optical Network" The OLT at the CO is running 32 gigabit per port. The fiber strand leaves the CO and heads to the FDH (Fiber distribution hub) where each strand hits an optical splitter. One fiber in, 32 out. These are the premise runs that run to each premise. Now 32 is not a hard standard. There are many flavours of PON. For gigabit 32 ports is pretty much the standard. but for lower service levels then more ports are possible up to 128. They typically come in 16, 32, 64, 96 and 128 port varieties but obviously the higher count will be slower speeds. The cellular nodes for example are direct fed 1 fiber per antenna with each one heading back to a port on a fiber switch. This is multi frequency fiber. There is a constant down stream channel, and a different wavelength used for the back channel which is TDMA access. I asked him why such a long fiber out of the sheath and his reply was they are told to leave 10 meters. I guess the idea being that they could technically run that into the garage directly to a termination block, and then a short patch cord to the ONT. I don't do that though, I run proper clearcurve to the ONT.

I've done Australian Government fibre-optic installs and they use pink ( salmon ) for there " secure communications " systems and the terminating box has to be see though at both ends, must have armour Conduit with metal nuts sealed with loctite, this is so all fibre runs are " Secure " and locked down with all ends that can be seen in box as not to of been compromise. I have some good pics but can't share.

We use fusion splicing on all outside plant. At the pole, or in the underground vault there is a NAP (network access portal) which has anywhere from 4 to 12 ports on it. (Each port has it's own fiber strand that is fusion spliced back to the distribution hub cabinet) A drop fiber is screwed into the port, and that extends to the house. At the house end, we cut excessive length (the drops come in 50 100 and 150 meter lengths with a connector on 1 end) and terminate with a connector. 2 types are used. My splice kit uses the corning optisnap connectors but there are other guys using a different type that do not require this crimp tool. They just cleave the end, stick the fiber into the end of the connector, and squeeze a couple of plastic tabs and the connector locks on to the end of the fiber. I prefer the system I use.

If you bend it too sharp then yes it will. I do this for a living every day. I have done literally thousands of splices using the Corning Optisnap, as well as fusion splicing. The biggest headaches for fiber, especially in underground installation is mice that crawl up the conduit. They love to snack on the fiber. We have a bunch oa very healthy mice all on high fiber diets out here.

This may seem like a stupid question, but why is fiber so much faster than copper communication? The idea of fiber is to use light as a way to transmit data over optic pipelines. But explain what makes this better than electrical signaling? Is it that light can carry more bandwidth? obviously we can use optics to carry large amounts of data over conduit for long distance, but at some point we must convert this signal to and from electric. We must use electrical signaling to modulate a laser to make fiber optic signal and again to convert it back to something our computers/ telephones etc can use. So what's the point?

@12voltvids

Fiber is faster only because it doesn't have attenuation like copper does. The longer the copper wire, the higher the resistance, and therefore the lower the signal at the other end. Glass is much more efficient in transferring the laser beam signal as it bounces down the light pipe. There is still attenuation, but over fiber the beam will travel over 25 KM without serious degradation. Copper on the other hand 1KM is about the physical limit before attenuation becomes a problem.

12voltvids this always confused me. DC is no good for distance because of attenuation/ loss. AC can travel farther but there are limits on frequency. Not to confuse power with telecoms but take mains voltage. At 60 Hz it can travel long distances without much resistance. Higher frequency systems like aircraft power which is 400 Hz range is good because of smaller transformers and wires however it's not good for distance because attenuation? RF same way. A 1 MHz signal can just about travel on open wire without loss but say, a microwave signal needs low loss coax

DSL comes in many flavors. The original DSL operated from about 200KHz to about 1.1 Mhz. This was known as DMT1. DMT2 followed and the bandwidth extended to about 2.2MHz. DMT2 had good reach, with a max speed of just under 10 megs. VDSL followed where the frequency was extended yet again. The first versions of VDSL supported a data bandwidth up to about 23 megs, and used frequencies going yo to around 4MHz. VDSL 2+ dramatically extended the carrier frequencies. 2 common modes were called 8B and 17A. 8B used froequencies from 200MHz up to 8MHz, and 17A extended this to 17MHz. 17A could suppprt 100 megabits if you were close enough. Of course as the frequency goes up, the distance drops. One way to increase the distance is to bond 2 ports over 2 lines (4 wires) On 17A profile this would allow well beyond 100 megs, and even on relatively long loops of 1Km or so, speeds of 75 megs were achievable. For people on really long loops up up to 1.5KM on a bonded loop they were able to get speeds close to 50 megs total, which is fast enough for multiple HD tv streams. Fiber ends all that distance crap though. Pretty much unlimited bandwidth on fiber.

How much time is that? I have hundreds of installs with them from 2013 until today that don't seem to have any issue. The Belden ones are a PITA and not many people have much success in getting them on right. Most people don't even get the Corning ones on right either. In the video he used the fiber handler with the cleaver. A lot of people don't do that and just use the universal insert. Also when placing the fiber into the connector, the fiber should be rotated between the fingers and with a bigger bend in the fiber while pushing in. That way you will see the VFL in the optisnap tool bleed out through the fiber letting you know you have great contact with the fiber stub, instead of relying on the gel to cover for mistakes. OP, you are supposed to give the red button on the cleaver a press before you press the cleave button to relieve any possible tension. I now just drop the fiber in the handler first and remove the cladding while in the handler. Less breakage, and saves even more time. Well, that is if I were to still be doing that job.
