In Real Life - GPON Fibre To The Home

[@shriramvenu]

very nice and informative video with actual use case examples. Its rare to get real equipment demos as typically these PON videos only explain things conceptually

[@fibconetfttxsupplier2424]

Thank you for the informative introduction to Huawei GPON technology! It was conducive. Looking forward to more educational videos about optical communication products.🥰

You should do a video on different between GPON & XGS-PON and possibly a separate video on the next gens like 25G and 50G Pon technologies.

[@lemagreengreen]

As I was watching them build out the GPON network in my area I researched all of this. I was struck by how complicated the actual network must look in a rural area, I know where the splitters are but properties are spread very thin so if you look at the telephone (now fibre, I guess) poles you can see all the individual cables, some travelling quite some distance from the splitters. From there there are occasional port blocks on poles particularly where there's a cluster of properties, they seem to use 4 port versions here but I assume in urban areas they are larger but each port is fed by an individual cable from the splitter, in some parts the cable strung between poles appears thicker so I assume they bundle multiple fibres? not sure. I'm not sure where the OLT is but I assume it is in the old telephone exchange buildings, many miles away in the case of rural fibre. It works beautifully though, a gigabit to a farm is pretty impressive and super reliable.

[@deepspacecow2644]

An ISP near me has a closure per customer. They use spliced cables, not connectorized ones.

[@Todd.T]

Depends. If there was a CO close by, the OLT could be inside in an environment proof cabinet. Outside, you don't have to pay for cooling. The max distance is 17km or 10miles. The more you split, the less the distance. Some of the splits are in line and unbalanced. So I can have a 1:2 split feeding a 1:8 split. The one side continues down the street and the 1:8 split feeds businesses with more splits on the end. Cable providers use the exact same large OLTs but they can also use OLCs which are mini clamshells that look like regular cable amps with fibre in and fibre out. The OLC can run on the same power the coaxial has on it, allowing for using an existng network with backup power. Everything is spliced and the splitters are the size of cigarettes or a few stacked credit cards depending on where they are.

[@markarca6360]

I am watching this video over a FTTH Internet connection.

[@CPD-KD6-3.7]

This was really cool! I was just wondering if I could use two fiber optic terminals as simple media converters to convert copper to fiber. I'm trying to network a barn that's a couple of kilometers away, and a wireless link isn't optimal due to the terrain, however there's a dark fiber that the builders installed before completing the structure. I know I should use an SFP module and a dedicated media converter, but the optical terminals are so much cheaper. Thanks in advance!

[@TheOpticalNetworker]

You would use media converters. It depends on what fibre you are using (Single or Multi Mode), the distance and the connectors on each cable.

[@schulteheimhotel7165]

[@Theggamer]

Thanks for the clear explanation. I reallywant to see how the network works outside this at the exchange level. Your videos seam to be the only with clear explanations. And show the physical hardware rather than just diagrams.

[@TheOpticalNetworker]

Glad it was helpful! It's based on my experience working on GPON networks.

[@Trident_Euclid]

This is the same way the new FTTH works in Oman. ISP's use TR069 for ACS and they require the serial number of the ONT too.

[@TheOpticalNetworker]

Good to know.

[@praveendissanayake2509]

Thanks a lot for this really informative video. I have a ftth pon connection here in Sri Lanka and my ISP has given me a Huawei ont router which also has wireless function. I've been wondering if I could use a third party router with this ont box since it only supports antiquated wireless n.

[@StashMc]

yes

[@akshaynarshi827]

Great video, hoping you make videos on different ISP’s and their service

[@TheOpticalNetworker]

What do you mean? The physical topology of these networks remains mostly the same.

[@akshaynarshi827]

TheOpticalNetworker for example what makes company X better then company Z, in terms of speed and connection stability.

[@johnnyvandenelzen2250]

The OLT shown in this video is a Huawei MA5800 X17 series? This would mean that the line cards can be either 1Gig or 10Gig ports interchangeably. Setting up your fiber network with GPON is only one of the options on how to form the (telecom)network. I work with the same OLT's but we simply use Point-to-Point connectivity between OLT's and home addresses. Each (duplex) optic provisions 2 separate addresses in our design. Btw, the required dBm values might differ with the use of different SFP's. Just thought it would be interesting to add this comment to your well-explained video. Oh and one more thing, the line cards are the second most expensive thing in the chassis, the supervisor cards are even worse when it comes down to economics. :) Just wanted to mention that.

[@ShOtZzFiNeSt]

Are you able to run combopon with the MA5800?

[@nabbe63o]

[@Hypocrisy.Allergic]

[@montatharhayder]

Thank you brother for this amazing explanation 🌹

[@stuartmulvaney]

You know your stuff make more videos on the fiber. big gap 2 years ago since last video

[@TheOpticalNetworker]

I have other obligations;)

[@csabasipos6525]

Well, your attenuation figures are a bit off: On the ONT side, you need to be between -8dBm and -28dBm (Class B+ ONT, 99% falls in this category). On the OLT side, there are a lot of Class C+ optics already, in this case you need to be between -12dBm and 32dBm. By using Class C+ modules at least on the OLT side, you can get 2-3dBm better performance even if your ONTs are Class B+ only, due to higher transmit power, and better receive sensitivity. Of course, even for your farthest customer, its better to take a 2-3dB margin, keep in mind that the fiber will age, so I would not plan for any endpoint below -25dBm.

[@TheOpticalNetworker]

I worked on GPON networks and those were the losses we worked with.

[@DowaneCharles]

Like me he works in the field...I was coming to show my expertise but you said I

[@Hypocrisy.Allergic]

from what i ve seen over -18 it goes downhill for ont and for OLT it s around -14

[@Theggamer]

If the connection is going to a splitter how is the speed set ? Is that on the customers side or is that via an assigned ip. I just thought each splitter had a address making it impossible to set the speed for the individual customer.

[@TheOpticalNetworker]

Both it will be done on the ONT and by the ISP. The speed is more of "software" thing - the hardware is capable in most instances of running higher speeds. That's where the VLANS come in.

[@FirstLast-qy7hf]

@@TheOpticalNetworker could you do a video explaining VLANs?

[@TheOpticalNetworker]

You can just search for VLANS on youtube there's nothing specific about them in the case of GPON.

[@garnerlegar]

Hi mate. I have been enjoying your chanel. Pleeas I want to get into fibre optic as change of career. What sort direction would you give me, training courses and centre and cost ? I live in North West of England. Thanks

[@TheOpticalNetworker]

Hi I trained with the Fiber Optic assoication and that's how I got into fibre. They have school worldwide and it looks like they have schools (not sure about the North West) here's the map foa-approved.org/map.htm. Try doing the CFOT course and taking it from there. They have free resources on their website: www.thefoa.org/tech/ref/contents.html#Understanding Your best bet is getting practical experience. Try phoning a company like Gigaclear and find out what they are looking for. I'd only take this job if you like hands on work and getting dirty. It can be messy tough job at times but I loved it. It's nice not being in an office.

[@garnerlegar]

[@menedenz8774]

Hi, Have you landed a job in this field, yet? I'm an Electronics and communication engineer, And just graduated, I want to get a job as an engineer in this field. I have good knowledge in networking, I took fiber optics at university and it was all theory so when I graduated I decided to study about CFOT (I'm halfway in) because I want to be as familiar as possible with technician work. like cables and splicing and instruments I'm a bit lost Could you advise me on what to focus on so I can go and earn the job from the first interview.

[@Mi_Fa_Volare]

Is GPON somehow unattractive or is it superior to cable's distribution concept?

[@wiziek]

By cable you mean coax? You can run only fiber from centrall office or street cabinet, no power inbetween only optical signal and splitters and spliced cables.

[@Mi_Fa_Volare]

@@wiziek What do you mean? Ever heard of FTTH? With cable I meant coax. What cable service and GPON have in common they're split. Cable doesn't seem to have a good reputation. So is it also a big deal with fiber? How bad of a choice would GPON be when comparing GPON with AON?

[@TheOpticalNetworker]

GPON will perform better than DOCSIS

[@Mi_Fa_Volare]

@@TheOpticalNetworker Oh, that was the word I couldn't remember. That was the answer I hoped for. I trust you for this answer to be substantial. How much is GPON better than DOCSIS? Also, can a GPON subscriber have a VLAN ID with tag, so I can use the fiber as a trunkport to connect to a tagged SFP port to eliminate the need for a converter/sort of modem? My idea is to split private internate gateway and business internet gateway (seperate internet subscriptions).

[@TheOpticalNetworker]

​@@Mi_Fa_Volare Okay your english is difficult to understand. If you want more detail on the advantages of FTTH over DOCSIS you can google that. As I understand you want to connect your directly to a switch or some other device to avoid your ISP router. You would need to speak to your ISP about that.

[@bohlokwamokabo7390]

Hi are you working at huawei SA?

[@AceCobra1]

I just had a home broadband installed which the guy showed me as tested at 956 MBps before he left. However, when I tested it myself, I can't seem to get it downloading/ uploading more than about 95 MBps. Do you know if it is possible for him to have programmed the GPON router thing is limiting the speed? I am thinking of purchasing a new GPON unit from Aliexpress to see if it improves the speed in case it is something inside the router unit that is limiting my max speed

[@TheOpticalNetworker]

There can be initial configuration issues. The speed is set both by the ISP and the fibre provider via the VLANS. I have had issues when I initially got my fibre and the speed was set to 10mb/s. I'd suggest you speak to the support staff for you fibre.

[@braamsnyman]

It sounds like your equipment is on a 100 Mbps port. Do you have a Gigabit switch? Everything in your network needs to be at least 1 Gbps equipment for you to achieve 956 Mbps.

[@ricmacas]

There is another possibility, that you are confusing Mbps with MB/s. They are not the same, in fact the values in MB/s are exactly 8x smaller than Mbps. You should expect 119 MB/s in download speed reported by most apps. If you need to know the connection speed in Mbps most Speedtest places will tell you in the correct unit.
