OLT4200

Compact 8-port GPON Optical Line Terminal


  • Compact 8-port GPON Optical Line Terminal

    The latest advancement from Alphion Corporation is the 1 RU OlT. This
    innovative OlT unit gives unmatched performance through 4 x 1 GbE
    (SFP) and 2 x 10GbE (XFP) uplink ports in a space and power conscious
    design. The AOlT-4200 mountable on the standard 19 inch rack feature
    compact design requiring only 1 Rack Unit of space saves valuable rack
    space. One of the industry's highest port density OlTs, easy installation
    and seamless configuration capability are just some of the innovations of
    this unit.

    Servicing many markets such as Telecom, CATV, Enterprise providers
    Alphion saw a need for a more versatile OlT unit that would benefit
    customers not only through more efficient power utilization but
    wouldn't diminish in performance as well. The built-in high performance
    switch of the AOlT-4200 supports Ethernet base layer 2 switching
    function, and provides up to 512 GPON subscribers.

    The advanced design of the AOlT-4200 offers the same functionality of
    the AOlT-4000 chassis family, supporting layer 2 functions as STP
    (Spanning Tree Protocol), Link aggregation, port-based VlAN, 802.1 Q,
    mirroring and DHCP relay and IGMP snooping/proxy for efficient
    transmission of multicast traffic.

    This original design also supports the IEEE1588v2 PTP and distributes
    ToD over GPON framing which is suitable for 2G/3G and lTE mobile
    backhaul applications.
