Teleste and Iskratel develop hybrid GPON/DOCSIS platform

Broadband and video systems specialist Teleste has worked with Iskratel to develop a proof of concept solution for the delivery of triple-play services that combines Iskratel’s GPON hardware with Teleste’s DOCSIS-based mini-CMTS (cable modem termination system), called the DOCSIS Access Hub (DAH).

The new technology enables operators to use existing last-mile coaxial cabling as an extension of their fibre-optic access networks. This significantly reduces the time and costs of deploying faster broadband networks. The solution also fits into locations where it is not possible to pull new cables, which is often the case in European historical buildings and city centres.

The combination includes Iskratel SI3000 Lumia aggregation node as GPON optical line terminal (OLT) and Teleste’s DAH as GPON optical networking unit (ONU). One DAH can bring the IP network to every apartment in a building using the existing coaxial cabling, and once a DOCSIS cable modem has been connected to the network, the services start running immediately.

A major benefit of combining GPON and DOCSIS technologies in this way is that it provides an economical way to deliver broadband connections inside buildings with a level of service equivalent to using fibre all the way, the companies claim.

“Teleste recognises the potential of DOCSIS used together with GPON in providing operators with a way to connect new customers to their high-speed networks,” said Olli Leppänen, vice president of distributed access for Teleste. “The last mile fibre is typically expensive and time-consuming to build, especially in brownfield areas. Where coaxial cabling is available, utilising the hybrid fibre-coax infrastructure provides operators with a means to optimise the costs and time to market when expanding the multi-gigabit networks.”
