This concentrator along with UTSTARCOM optical network units is a final decision of arrangement of access networks for private and corporate users with gigabit bandwidth at passage of last mile.

Low-budget concentrator BBS 1000+ performed in case 1U is a chassis of 280 mm high with six slots that subject to the customer’s needs can be completed with the following functional modules:

  • 1 slot for GSM module (contains 4 ports of 1000-X SFP Gigabit Ethernet and control ports); - 2 slots for two 4 port EPON modules;
  • 1 slot for ventilation module;
  • 2 slots for one ac power module or for two backup dc power modules.

That allows growing possibilities of the network being built stage-by-stage.
    All the modules have “hot” replacement function that reduces considerably time of recovering of system operability.
    BBS 1000+ has high-speed non-locked interconnect matrix.
