RF over Glass:

Fiber-to-the-Home with DOCSIS and DVB.

As the merging of TV and Internet gains momentum bandwidth requirements are increasing. TV services in HD format - and soon ultra HD - are the main driving forces. In this context the cost-intensive expansion of optical fiber networks has become a hot topic for debate. Cable providers and city carriers are looking for cost-efficient solutions to upgrade their existing network infrastructures to the level of FTTB (Fiber to the Building) or even FTTH (Fiber to the Home).

The use of the RFoG technology (Radio Frequency over Glass) is considered a high-performance option. RFoG is a passive optical network that transmits HF signals via fiber to the subscriber. In a downstream direction it works similarly to a HFC network. With Optopus, WISI offers an optical platform that is exceptionally powerful for this application. The modular system is particularly flexible, displays high density, is very reliable and is usable in FTTx networks for RF over Glass, RF Overlay and HFC applications. Optopus and the RFoG technology offer network providers a further advantage. They can continue to use previous investments, such as provisioning and billing systems, CMTS platforms, headend equipment, set-top boxes, conditional access technologies and cable modems.
