xPON solutions
GEPON is a perfect combination of Ethernet technology and passive optical network technology. It eliminate the usage of active fiber optic components between OLT and ONU, this will greatly cut the cost and make the network easier to maintain. PON means passive optic network, EPON is integrated with Ethernet technologies, and GEPON is a Gigabit EPON. GEPON system is designed for telecommunication use. GEPON devices are fully compliant to IEEE802.3ah.This series products features high integration, flexible application, easy management, as well as providing QoS function. The fiber network speed can reach up to 1.25Gb/s and each EPON OLT (Optical Line Terminal) system can distribute into indicated number of ONU (Optical Network Unit) to build up the fiber passive network with the advantage of big capacity of data transmission, high security, flexibility of buildup network, mainly applies for FTTH (Fiber To The Home) projects, which can access to IP telephone, Broadband data and IPTV.
JSC "Dicto Citius" deliver solution and equipment for ISP of high-speed voice, data and video GEPON solutions dedicated to residential and business subscribers. FTTx, or GEPON in particular, supports multiple applications and services including VoIP, enterprise focused services, "Triple Play" services and RF Overlay, among others.
