Multi Play - Band Width Bonanza for Telcos/MSOs on High Capacity High Speed Coaxial
CATV Access Network to Homes and SMBs
Summary
1. Telcos and MSOs in India are poised to exploit the band width bonanza of LCOs
last mile co-axial CATV network to homes and SMBs. 2. From the optical node of LCOs
HFC access network, on an average 300 homes are passed. In some cases, the number
of homes passed goes beyond 600. 3. As there is a very high penetration of CATV
in India, thus for 100 % homes connected to one optical node, both down stream and
upstream band width is really huge. This band width bonanza is very attractive for
telcos and MSOs to interconnect their networks to LCOs access network to offer multi
play to homes and SMBs.
Analysis
India follows CCIR CATV RF frequencies for channels allocation to provide PAL
TV services .
As digitization of TV has started gaining momentum, all three services like analog
TV, digital TV without CAS and digital TV with CAS are being provided in a product
mix to ward off the competition from DTH as also meet the increasing demand
for digital TV. However, IP over Ethernet over Cable (IPoEoC) is being tried out
but not yet commercially launched on large scale. Telcos and MSOs are pondering
as to what should be done to exploit the band width bonanza available with LCOs
last mile to homes and SMBs.
Just to get an idea of this band width, consider that only 13 RF channels are
available for digitization in the forward path. One RF channel of 7 MHz can yield
up to 40 mbps and thus 13 RF channels would provide 520 mbps to each 1 km coaxial
line passing minimum 150 homes. For the up stream, if only three RF channels are
digitized, the same 1 km coaxial line can get 120 mbps. This D/S band width of 520
mbps and U/S band width of 120 mbps passing 150 homes can provide true broad
band experience finally including the base level multi play services of voice,
broad band Internet, IP TV and FMC deploying IPoEoC technology from optical node
of LCOs right up to homes or SMBs.
The telcos have multiple points where their IP/MPLS BW can easily be aggregated
and back hauled like MSC/DLC/hub site/fiber site locations where LCOs optical
nodes get interconnected through telcos fiber. Thus, technically IPoEoC
can be deployed as an end-to-end network to offer multi play to millions of homes
and SMBs. The LCOs only need to convert their last mile co-axial network into
two way which does not cost more than USD 6 per point.
The above is a hot combination of telcos/MSOs and LCOs interconnected together
realizing a huge band width right up to homes to launch multi play in India without laying
time consuming and capex intensive own cables. FTTH can be started in all new colonies
in coordination with real estate companies but existing more than 100 million homes
can be served through such a band width bonanza already available to homes and SMBs.
