Teleste and Iskratel have teamed up on a proof of concept (PoC) that combines DOCSIS and GPON technologies. It's intended to enable operators to use existing last-mile coaxial cabling as an extension of their fiber networks. The joint solution combines Iskratel's GPON technology with Teleste's DOCSIS-based mini-CMTS, the DAH (DOCSIS Access Hub).
"Teleste recognizes the potential of DOCSIS used together with GPON in providing operators with a way to connect new customers to their high-speed networks. The last-mile fiber is typically expensive and time-consuming to build, especially in brownfield areas. Where coax cabling is available, utilizing the hybrid fiber/coax infrastucture provides operators with a means to optimize the costs and time to market when expanding the multi-gigabit networks," said Olli Leppanen, vice president of distributed access for Teleste.
The combination of GPON and DOCSIS technologies is intended to allow a fast and economical way to deliver fiber-level broadband connections inside buildings with a level of service that equals using fiber all the way.
Operators can now use the Iskratel SI3000 Lumia as a GPON OLT and Teleste's DAH as a GPON ONU to deploy triple-play services. One DAH makes it possible to bring the IP network to every apartment in a building using the existing coax cabling, and once a DOCSIS cable modem has been connected to the network, the services start running immediately.
The solution also fits into locations where drawing new cables is not possible, as in many European historical buildings and city centers.
