GPON OLT 4000N

4000n

19″ Optical Line Terminal Chassis


  • Optical Line Terminal Chassis

    The AOLT-4000N Optical Line Terminal family is an affordable, scalable, high-availability platform that provides carrier-class, reliable and secure services to over 5000 Optical Network Terminals, and thousands of users on 40 separate GPON access interfaces – all from a single, AOLT-4000N chassis.

    The AOLT-4000 family can be configured with single or 1+1 redundant controller cards, single or 1+1 redundant switch cards and up to ten 4-port GPON line cards. It also has redundant power, fan, alarm and timing interfaces for delivering true carrier-grade services.

    Up to four AOLT-4000 chassis can be configured in a single bay, and multiple bays can be managed from a single AEMS management workstation, providing services to even the largest GPON access network.

    The AOLT-4000 supports ring and star fiber architectures as well as fiber path protection. The system has been designed with sophisticated quality of service capabilities, the highest level of security, and the most advanced management capabilities for delivering Triple Play services.

    Applications
    The AOLT-4000N is designed for Carrier Central Office or MSO Hub environments for enabling costeffective FTTx services.

    Flexible Configuration
    Two control card slots for 1+1
    Control cards. Two switch slots for 1+1 Aggregation switch cards with redundant 1 O-GbE and 1-GbE Service Node Interfaces (SNI) uplinks. Ten line card slots.

    Data Plane Connectivity
    The AOLT-4000N's data plane consists of redundant 1 O-GbE connections to each card slot from the two dedicated double-width AOLT-4000-SWT slots in the shelf.

    Control Plane Connectivity
    The AOLT-4000N's control plane consists of redundant 1-GbE connections to each card slot from the two dedicated AOL T-4000-CTL slots.

    Synchronization Connections
    Inputs for redundant BITS/SSU timing for GPON and TDM synchronization and outputs for sourcing clocks for external synchronization use.

    Switch Capacity
    Dual star redundant architecture with
    20 Gb/s bandwidth to each card slot and 400 Gb/s bandwidth total capacity.

    High Availability
    High Availability architecture where removal or insertion of any single card does not affect existing connections on other cards. Even in a system with a single AOLT-4000-CTL card, a failure of the control card does not affect the working traffic. To increase control plane availability, a second mate AOLT-4000-CTL card can be inserted in the AOLT-4000N chassis, providing 1 1 redundancy for the control plane. Likewise to increase data plane availability, a second mate AOLT- 4000-SWT card can be inserted in the AOLT-4000N chassis, providing 1 1 redundancy for the data and signaling plane.

    AEMS or SNMP Managed
    With the AOLT-4000-CTL card insta lied the AOLT-4000N is either remotely or locally managed from either Alphion's Element Management System (AEMS) or with a 3rd party EMS using SNMP or a legacy NMS.

  • Capacity
    2 slots: redundant control cards (AOLT- 4000-CTL)
    2 slots (double-width): redundant switch and timing cards (AOLT-4000-SWT)
