FV-NS253 is an Industrial XGS-PON ONU. This ONU is fully developed based on the standard IEEE 802.3av(10G EPON) and ITU-T G.9807.x(XGS-PON) and belongs to a 10G symmetric PON, with an uplink and downlink rate of 9.953Gbps. It aims to meet the FTTH ultra wideband access requirements of home and SOHO users. It supports NAT/firewall and other functions.
The FV-NS253 ONU provides industrial-grade high-reliability ONU. It supports lightning protection of up to 6 kV and high temperature resistance of up to 65 degrees, and is compatible with OLT of various manufacturers. What’s more, it supports the selection of POE power supply function, facilitates the deployment of POE monitoring probes, supports Gigabit ports, and ensures smooth transmission under large burst video traffic. The metal shell has good field adaptability while ensuring heat dissipation.
