  • Maintain clear and constant-level signals with minimal Far-End/Near-Far effects
  • Mitigate uplink noise
  • Wide spurious-free dynamic range
  • Low noise & minimal signal distortion


  • Ready to support all public safety and land mobile communications
  • Resiliency with redundancy
  • Harden for commercial and industrial environments
  • Full visibility and monitoring with NMS ready for NOC
  • Proven saving in costs, time, labor, space, and energy
  • Platform adaptable to changing needs via software configuration

FTAS Headend

Simplicity ● Performance ● Confidence

FTAS Headend connects the RF resource and Remote Active units via fiber to extend wireless coverage.  Designed with manageability and resiliency, the Headend is equipped with embedded element management for remote control.

Fiber Transceiver Module

The Fiber Transceiver Module (FTAS-HE-FTM) converts between optical and RF signals while minimizing loss caused by varying fiber lengths and temperature fluctuations.

Each module supports Fiber Optics Receiver, Transmitter, or Transceiver components, where each can connect up to 4 Remote Actives.  It supports uplink, downlink, and duplex as well as up to four frequency bands.  Each module is equipped with dual element management components for resiliency, and can house up to 10 FOTR, FOTX, or FOTR per module chassis.

Active Multiplexer Module

The Active Multiplexer Module (FTAS-HE-AMUX) filters and amplifies signals by band.  It supports downlink or uplink, with the option to support single, dual, triple, or quadruple bands.

Digital Signal Processing Module

The Digital Signaling Processing Module (FTAS-HE-DSP) sets the signal output regardless of the received signal power via Automatic Level Control (ALC) on the downlink path and Automatic Gain Control (AGC) on the uplink path.  As a channelizer, the DSP provides narrowband filtering to mitigate excessive noise and improve adjacent channel rejection and the dynamic range supported

FTAS Central Power Supply

The Headend Power Supply (FTAS-HE-PWR) is an internally hardware redundant 48-volt 600-watt switching power supply.  This module powers all connected Remote Actives centrally.

FTAS Network Management System

FTAS Network Management System (FTAS-NMS) is the command center for the entire DAS network.  With a full view of the DAS network and its components, FTAS NMS provides at a glance the current health status of the network, notifies staff when attention is needed before impacting users, and makes adjustments to individual elements to optimize performance. 

Authorized users can access NMS data and received notifications over mobile devices additional to NOC terminals.

As the network expands or changes, FTAS-NMS can remotely reconfigure the network and elements to add/change supported frequencies and upgrade network software.

All FTAS active products and components are equipped with element management capabilities, controlled via FTAS NMS centrally (preferred), via web interface for individual element, or directly.
