What is GE-PON?
GE-PON
(Gigabit Ethernet-Passive Optical Network)

GE-PON is a transmission technology that utilizes fiber optics and shares multiple lines to realize data transfer rate of 1Gbps. This technology is attracting attention as it enhances the transfer rates of high-speed Internet connection services by fiber optics while reducing the cost by sharing multiple lines.
GE-PON is standardized as IEEE802.3ah standard and is expected to be adopted by virtually all carriers who provide optical Internet services by 2005.

Features
    I. Security functions
    * Equipped with the function to encrypt the communication data between the center device(OLT:Optical Line Terminal) and the subscribers' terminals(ONU:Optical Network Unit).
    * Equipped with the function to authenticate ONU.

    II. Advanced bandwidth control capability
    * Equipped with DBA (Dynamic Bandwidth Allocation) function that efficiently control the bandwidth with low delay.

    III. Basic design that allows to add 1550nm band signals
    * 1550nm band signals that are used for CATV can be added to the same fiber optics.

    IV. Highly reliable optic devices adopted
    * DFB-LD (Distributed Feedback - Laser Diode) by Sumitomo Electric Industries, Ltd is improved to have higher output for this device to realize stable communication.

    V. Excellent maintenance and operation performance and technical supports
    * Equipped with an authentication server connection port and outbound management ports.
    *

    Web browsers, SNMP, IGMP Snooping, etc are supported.

    * Manager/F, a GE-PON management software that has past field records in ADSL, is also available.
