Full screen XTREME 256

General Description:

The XTREME 256 next generation L-band matrix switch features 256 ports in a compact 12 RU chassis. The XTREME 256 is a full fan-out (distributive), non-blocking switch where an input can be routed to any or all outputs. The XTREME 256 features an industry exclusive flexible matrix architecture (patent pending) that supports both symmetric and asymmetric configurations of 256 combined inputs and outputs in a single chassis. Asymmetric configurations such as 64x192, 96x160, and more can be implemented as well as the standard 128x128 configuration. It is designed for maximum reliability with redundant power, fans trays, and control cards plus RF redundancy. It is also designed for ease of maintenance with built-in self-test (BIST) capability and the ability to hot-swap all active components from the front of the unit. The XTREME 256 is highly scalable and can easily be expanded up to 2048x2048 using multiple XTREME 256 modules. Optional integrated expansion ports allow for large systems without using external expansion modules, significantly reducing system size and the number of cables.

Features & Benefits:

  • Compact modular design, 256 ports in 12 RU, easily expandable to 2048x2048
  • Asymmetrical configurations up to 248 outputs in a single chassis
  • Adjustable gain on inputs and outputs to allow RF performance optimization
  • Touchscreen local control and embedded web GUI interface
  • Easy hot-swap of all active cards, power supplies, and fan trays from the front
  • Redundant hot-swap control cards plus independent GUI control system
  • Remotely controlled via web browser GUI interface, SNMP, TELNET or TCP/IP via customer supplied PC
