PON Physical Layer Security
Is a PON network secure?
In some of our earlier videos we described the security risks in PON networks and the mechanisms that are used to address them.
However, some of our customers still had some doubts about the security of the fiber media itself, so we created this video to dive into this subject.

Introduction to NG-PON2
Просмотров 5 тыс.4 года назад
NG-PON2 is the most advanced PON technology available today, with line rates of up to 40 Gb/s in every direction. In spite of this it has limited adoption among service providers, mainly due to its costs and technical complexity. This video explains what NG-PON2 is and how it works, and describes its main benefits as well as its challenges. To learn more you may watch the webinars on our websit...

IPTV is a major opportunity for service providers to expand their business offering, and GPON is the ideal technology for delivery of IPTV services. On the other hand, IPTV is one of the services in which customers are less tolerant to service and quality issues, and thus troubleshooting such issues when they occur is critical. This video gives you guidelines how. Before watching this video we ...

Such a life saving video, thank you so much.
Hi.. I'm having a weird issue where my ONT refuses to push upload throughput unless I run a speed test from the unit itself.. Is this a configuration/QoS issue?
Tom Paris and Harry Kim?
Hi.. I have an issue where Im getting low throughput unless I reseat GPON connector. Any idea?
very good and straight fwd
You mention at 0:23 that Harry can't 'talk' to Tom due to physics, what are these physics and could Harry talk to Tom on a different wavelengths ?. What I thought was you could have your 'own' local network with a neighbour over the branch PON network. Alternatively, if only one person has a registered internet access and share it over the PON on another wavelengths :). Another 'problem' could be a nefarious person could 'shine' light on 1490 and 1310 wavelengths and disrupt that PON segment ! would this be an issue ?
These physics refer to the characteristics of the PON splitter, specifically a parameter called directivity. When light is injected into one of the output ports of the splitter, some of the light propagates back through the other output ports. Directivity is defined as the fraction of power transferred from one output port to another output port, and in PON splitters it is typically higher than 50 dB. The difference between the maximum transmit power of the optical transmitter and the minimum sensitivity level of the optical receiver is less than 40 dB, so directivity of 50 dB means there is no way for one customer to receive the transmissions of another customer. This applies to any wavelength. Regarding the question of a person who could 'shine' light and disrupt that PON segment, if the light is at the 1310 nm wavelength it would definitely disrupt the PON, so yes - it’s a potential issue. It is similar to a rogue ONU, and you can learn more about it in our video “Detecting and Identifying a Rogue ONU/ONT on GPON”, ruclips.net/video/9zPcbumcKzA/видео.html.
@@tracespancommunications6556 Thank you for your prompt and concise reply ! I thought afterwards about prisms and light isolation. Another thing that intrigues me is bandwidth on a PON segment and splitter ratios. If the PON speed is at say 1G each split would halve the throughput but not the speed of each packet ?. So each customer would get 1G but in 'small' bursts to the split ratio ? - I think of cars on a single track road being 'split' off each car to side roads, say each 32nd car in a 1:32 splitter ratio down a specific road - I hope that makes sense !
@@SolarPV. In general, the total available bandwidth of the PON is divided among the different customers, but there are some other points to consider: 1. A customer doesn’t use all his available bandwidth all the time, and as a matter of fact, most of the time he/she will use only a portion of it. Based on this, service providers can offer service packages based on oversubscription. As an example, they offer a “1 Gig” service, even though if 3 customers make an attempt to consume 1 Gb/s simultaneously, they will exceed the total available throughput of GPON. 2. For some types services the same downstream traffic is broadcast simultaneously to multiple customers. The classical example is IPTV, in which each TV channel is transmitted only once on a multicast port, and multiple customers connected to different ONUs on the PON can watch it simultaneously.
@@tracespancommunications6556 Thanks again !, Most users as you say only use bursts of data. But overall I feel it has the possibility of being a big bottleneck - I'm a frequent bittorrent user for example ... :-)
8:45 What application should I use to get this message?
Thanks a million for your videos
mira este nuevo pon con varias landas sobre la misma fibra , da mucho juego
great video thank you!
Love from Pakistan
vado.
vorrei una identità, vorrei essere riconosciuta in quanto tale , vorrei riconosciuti i miei diritti. vorrei sapere da dove vengo, e finire vicino al mare con la pace nel cuore. perchè è così difficile? voglio attaccare tutti e 4 i miei dispositivi. e fare le mie ricerche.del resto se nessuno mi aiuta che altro posso fare?
perchè non mi avete fatto lezione così finoadesso? io deo fare molte domande. ho bisogno di interagire con una persona reale. io nn ho molto tempo.scusate la mia insistenza grazie.
protocolli grazie, automazione, network as a code
no non è ok, se parla con me.mi dia il tempo di riascoltare il video da capo prima di passare al successivo.grazie
quindi se è un collegamento stella dove sta la collisione mi scusi?
grazie infinite.thanks a lot
ma come prima ero il EDGE più performante e adesso devo stare attenta a due IPv4? perfavore....
perchè allora Gpon ad esempio ha 4 ethernet? che significa? non posso uscire? allora gli switch e router a che servirebbero?quali collisioni? ma se con la virtualizzazione ne ho 6 su una sola macchina... c' è qualcosa che nn mi torna...o meglio.io ho capito.quando ne parlerete al pubblico?
mi può aiutare a progettare una distribuzione con 4 server perfavore?
ho la fibra in casa
il mio caso è diverso.non è quest la ragione, il mio GPON ha altri parametri. in ogni caso è "qualcuno" che decide quanti server posso montare. i conti li so fare. certo che se ho 1000 IPv6 assegnati...ritengo che tali scelte spettino al consumatore, che peraltro PAGA la connessione. Altrimenti dovremmo essere pagati (molti di noi)! vedi ROI (non mio).Grazie
How many cards does it have OLT , each port how many subscribers can each port accommodates !
Great job Oded! Nice to hear you virtually here in RUclips!
Good explanation, yet my question wasn't answered: what makes different GPON from PON? Is PON just a general term to refer to passive optical networking and GPON a more specific concept?
GPON is a PON network with capability of transmitting data at Gigabit speed. The same with XGPON a PON network with 10G data transmitting capabilities.
PON Means Passive Optical Network. It Means the cabling between the Provider (OLT) and Customer (ONU) is a Fiber Optic Network that does not have Electronic Power equipment but Just passive Splitters like your TV splitters only that this one splits the incoming fiber into several fibers 32/64/128
how did you do it can you share with me , thank you
