G.fast technology is the next generation of broadband service delivered over traditional copper networks, widening the spectrum to 106MHz, and 212MHz. G.fast offers a more cost effective roll out option than fiber by allowing the service provider to re-use valuable existing copper plant.
The SP-809 is a splitter module that has been specifically designed to complement the functionality of G.fast over VDSL application at CPE side. It provides Line port, Phone port and Modem port.
Features unique to the G.fast Splitter include the addition of secondary surge protection. This protects against lightning strikes and power crosses, reducing weather related failures and service calls. Secondly, the splitter offers additional protection of the equipment in the house reducing equipment failure due to surges.
The circuit protection will be provided mostly by standard central office line protection means and additional protection measures built into pots splitter to protect against line overstress which could damage the splitter itself.
