ABN should be able to broadcast OTT on the Unifi fiber back bone. Basically they use the TM fiber to send IP encapsulated DVB-C signal until to the junction outside your house, then from there it is converted back to cable signal.
Good point and suggestion. You are correct to say... "
send IP encapsulated DVB-C signal until to the junction...". The underground fibre cables are connected to "distribution ports" and then from there, different type of cables are used to the homes. Mmm.. I forgot the actual name for such "distribution port".
As info for others here, the fibre cables (UniFi) used for transmission refers to the cables laid (buried) underground outside the homes/condos/apartments. Different types of fibre cables have different specifications. The cables used for connection to the homes are different. I do not want to go technical on this but only in layman explanations. Each fibre cable used have a huge bandwidth capacity which is enough to carry digital signals for TV SD/HD channels, Internet packets, phone, etc. BUT
each fibre cable does have limits. I don't know the cable specifications used by UniFi so I can only estimate for how many UniFi users that each cable can support.
Ok... basically TM will not just simply allow any other competitor to use its own fibre cables because they have laid underground cables for a limited number of users. If TM allowed it, then they will not have enough for its own use when their own UniFi customers increased. For example only, when TM laid 10 fibre-optic underground cables for allocation to one or two condo buildings, its sufficient for only 500 UniFi users.
Without info on the cable specs, I don't know the maximum capacity of each cable. Ah... when the demand increased to more than 500, TM will literally and actually start "digging" again to put in more cables. Of course TM will install much more underground cables than needed, maybe 20 cables for 1000 users eventhough there are only a maximum of 500 homes. TM will then be prepared for future demands.
I am quite certain that ABN will NOT use the UniFi cable system. I don't have ABN inside news so I am not sure that this will change in the near future... maybe new joint-ventures with UniFi, agreements on temporary and limited use of some UniFi cable system in some areas, etc.
EDIT: Hehe... I better use "am quite certain" and replaced "can confirm" because I could not get 100% proof of my confirmation so there is a chance that I can be wrong.
Details obtained from ABN official website, (at the right of main page and posted by "starintech" about 58 days ago) http://www.abnxcess.com/index.html... "KL: Asian Broadcasting Network to launch Hybrid Fibre-Coax (HFC) network in Q2, 2012 using Motorola Mobility equipment and services."These are the reasons why ABN did not use shared UniFi cables...
1) Laying of fibre cables, router ports, jumpers, distribution servers, bridging connectivity and other system infrastructure costs LOTS of money and is limited to a maximum depending on how many underground cables have been laid. I don't think TM will be foolish enough to allow ABN to use its limited resources. Well... TM can always charge costs + BIG profits to ABN for increasing the number of underground cables but will ABN want to pay it ? Mmm... its very costly and I don't think ABN wants it because ABN will then add this extra costs to their Cable TV subscriptions and may make them not being able to compete with UniFi with lower subscription rates. In the long run, if I am ABN, I will choose to use my own cable system from another independent systems supplier.
2) I have earlier posted much info on ABN so please read it here...http://forum.lowyat.net/topic/2114557/+920# . They have already signed agreement with Motorola Mobility to use their cable system network infrastructure. Motorola Mobility IS in the process of finishing the system cabling and other necessary work. When completed, this will allow ABN Xcess Cable IPTV targeted to be launched in April/May 2012 in selected areas in Klang Valley. ABN nerve centre is at the ABN Puchong Gateway Broadcast Centre. Mmm... is it possible for more delays ? Did not find any news... available in which Klang Valley locations and what are the package subscriptions ?
ABN is a very new company so very little info at their website. I believe ABN Xcess is only for some areas in Klang Valley, NOT nationwide. Using fibre cables to go nationwide ?? ..mmm.. I can go on DREAMING FOREVER because of so many reasons which makes it almost impossible.Its not a question of the technical specifications of signal transmissions or fibre cables because all of the present and future TV broadcasters already knew about the potential of cable systems using hybrid-fibre-coaxial (HFC).
Scientists have already begun testing blue-light spectrum as a potential replacement for the present red-light spectrum because of the much much much bigger bandwidth that blue-light spectrum can carry. Is it possible to use long distance
fully fibre-optic, not HFC, underground cables ? At the present time, is fully fibre-optic used ? I don't know and what are the limitations that caused it not being used. Blue-light spectrum is applicable for equipment such as blu-ray players, medical equipment, etc.
Note : I changed the wrong word used, "fibre-optic" to the correct "fibre" word. My thanks to my many online friends for correcting me, hehe.This post has been edited by jamesleetech: Mar 16 2012, 06:08 PM
