Re: [MB] fibre in Winnipeg? My brother had a 100/10 modem, mine are only 100/5... Had to try haha |

I guess it depends on what department you work in. Network Services considers DOCSIS = Internet and Phone/SDP=Telephony. Regardless, even w/ convergence, there is no Internet specific 256 QAM carriers on FTTP nodes; only TV (Broadcast), VOD (SOD) and Phone (SDP). DOCSIS Internet cable modems will NOT lock up on FTTP nodes, regardless of GPON or EPON as there is no RF carrier for them. |

said by S1L1K0N: For our GPON and EPON nodes there is no DOCSIS narrowcast services.
That isn't quite correct. DOCSIS is present for telephony and some set top signaling at this time.

Kevin, you are correct. The services that you mention (VOD and Telephony) are called 'narrowcast' because their signal origination is at the regional hubsite; the TV services we call 'broadcast' because we acquire and combine them at a primary hubsite where they get redistributed to the regional hubsites. For our GPON and EPON nodes there is no DOCSIS narrowcast services. |

Sending only what is required is more cost effective.  |

Would that then mean it isn't a complete copy of the RF system? Only parts of it? -6 or 8 downsteam QAMs left off and the 4 upload for the internet?
Not that it matters

Not on our system Kevin, since we're only doing TV and Phone on RFoG. But on a provider doing data via RFoG? It's possible. |

| reply to kevinds
The ONU is the device which converts the RFoG wavelength to RF and vice-versa. The ONT is the 'fiber' modem; it converts EPON to Ethernet and vice-versa.
The Fiber to the Premise (FTTP) nodes have a dedicated chassis for Internet services. There is no DOCSIS (Internet) signalling on the ONU as the EPON service runs over it's own wavelength (optical channel) through the ONU and drops out to the ONT. Each FTTP node has it's own GbE uplink to the Internet, where as the uBR DOCSIS Internet chassis are either fed with 2 or 4 GbEs, except in larger markets where they have a 10GbE uplink; but this bandwidth is shared accross the entire chassis. |

yyzlhr is correct. The RFoG ONU is used only for Phone and Television (in Shaw's implementation). The data comes off the EPON/GPON ONU.
Anonimuz is not quite correct. The DS/US signal space is still shared. |

Would it not have the same internet congestion issues?
Yes, a lot of cable providers like Rogers are using these to deploy fibre straight to the home in the interim. This type of deployment allows them to use the same DOCSIS CPE and provisioning equipment. This basically only allows them to offer the same services they would offer over a traditional HFC setup, but it saves the provider money. It also allows them to convert the setup into a true PON based setup when they need to.
Based on the pictures posted here it looks like shaw only uses the media converter for telephony and video. Internet traffic goes through an ONT. |

| reply to kevinds
It would be similar to having a node just for your house. Congestion occurs when too many subs are on one node. |

Absolutely correct. EPON(Ethernet Passive Optical Network) != AE(Active Ethernet). Connor M - EPON uses an optical splitter architecture. AE does NOT. thanks for clearing that up, i hope you are correct cause i guess ill just take your word for it

Re: [MB] fibre in Winnipeg? said by HeadSpinning:said by kevinds:I wonder if that "mini-node" can be changed to output the non-encrypted digital (HD) channels... Humm....
The "mini-node" simply converts the RFoG signal to RF. It has no "brains" at all. It simply outputs an RF copy of the signal sent in to it's counterpart at the head end. That's right. It converts an analog optical signal to an analog RF signal. It's a pure analog media-converter. |

that is cool, and i called shaw FTTP today and the guy barely knew what he was talking about but he did say he thought it was epon, i guess i the one shaw employee provided me with the wrong info, thats honestly amazing shaw has tech support people with such lack of understanding of the tech, owell

It will look the same, except the ONU is from Arris or Aurora. |

yes i am, thank you, now we just need to wait for the user who was posting about the fiber to post photo's, i wish there was already some photo's up of a shaw epon setup |

| reply to Connor M
I'll let Shaw_Alex know and he can likely ask that question.
Are you satisfied now though? |
|
| reply to corbin
? why do the fttp team say otherwise?
i guess ill call shaw again and see what they say |

Here is my profile there: »community.shaw.ca/people/corbin
Shaw_Alex can verify if you want to PM him.
I work for Shaw Engineering in the same group as the folks who do our PON services. My own speciality is CMTS.
Residential = EPON.
Shaw Business = GPON.
It's great to see so much excitement. Have a great day everyone!

lol im not even arguing anymore. i already called shaw fttp team and they said everything is and will be GPON but some people have decided to argue with that so i have been trying to get some legitimate evidence of why users thought shaw was using EPON for residential and thought that may have been shaws initial plan or idea, it is not anymore, simple as that, as far as im concerned EPON is active e, its the same thing, not gonna even bother arguing with u. and i dont get what ur trying to prove as i have already proven and stated shaw uses gpon like 10 times, i also said in an above post that i never said shaw does not use EPON, i said they are not using it for residential, and they arent, even tho they may have before.
