Project Description

Vnet 2508E


A lot of ISP want to use FTTH network to deliver high speed broadband to more customer.
But some locations are hard to reach with fiber. The effort required to trench cable, dig up yards and rewire households varies widely, adding complexity and cost.
NITUS’s G.fast solutions breaks down barriers to fiber deployment and clears the path to high speed broadband. The right G.fast solutions will help you.

  • Deliver fiber-like speeds over the last mile of existing copper infrastructure
  • Reduce CAPEX by deferring the cost of extending fiber to every building and home
  • Extend high speed broadband to locations where fiber deployment is difficu


  • 32Gbps Switch Capacity
  • 8 x 1Gbps G.FAST ports
  • 8 x POTS ports
  • Up to 2 x 10GbE uplink connections
  • No speed degradation by packet size
  • L2/L3/L4 Traffic classification/Priority management
  • Diverse QoS mechanisms (SP/WRR)
  • Multicast Support for IP-TV : IGMP v2/v3
  • IPv6 Hardware Ready Platform
  • SNMPv2/v3 with RMON, Alarms
  • DoS resilient platform: Broadcast/Multicast storm control
  • Authentication by RADIUS, 802.1x
