COMNET FDXT1/E1S1(A) Overview

The A-End T1/E1 Point-to-Point Single-mode Transceiver from ComNet transmits AMI and B8ZS data signals over a single-mode optical fiber when paired with the A-End unit. The transceiver synchronizes and regenerates data to eliminate jitter accumulated through the link. It can be used with a single-mode optical fiber. The plug-and-play design ensures ease of installation requiring no electrical or optical adjustments. The transceiver incorporates a bi-color (red/green) indicating LED for monitoring proper system operation. The FDXT1/ E1 standard size unit can be either wall or rack-mounted in a ComNet card cage.

  • Robust design assures reliability in unconditioned out-of-plant/roadside environments
  • LED status indicators confirm operating status
  • Designed for installation in harsh out-of-plant/unconditioned industrial or roadside operating environments (-40 to 158°F ambient)
  • Fully compliant with the environmental requirements of NEMA TS-1/TS-2 for Traffic Signal Control Equipment
  • Remote Fault Indication allows the user to determine when a fiber break or loss of prime operating power has occurred, or a transceiver in the field has failed
  • Voltage transient protection on all power and signal input/output lines
  • Optical attenuators are never required thanks to the Wide Optical Dynamic Range
  • Hot-swappable rack modules
  • Interchangeable between stand-alone or rack mount use  
  • Single fiber design
  • Can be used in T1/Ds-1 and E1 telephony networks, ITS / traffic signal control equipment, building automation and environmental control systems, and computer/data equipment
