E8 Node

The E8 is a compact optical node, but there is much more than a neat appearance behind the simplified white finish. True excellence lies beneath the cover. These capable optical nodes combine outstanding performance and practical functionalities.

The E8 is a compact optical node with one active output. Based on the latest GaN amplifier technology, the E8 offers a high output level (CTB/CSO 116.5/116.5 dBμV) and supports 1.2 GHz/204 MHz bandwidth.

Features at a glance:

  • 1.2 GHz 2nd generation GaN technology
  • Return path supports 204 MHz bandwidth
  • Optical AGC (OLC)
  • Electrical adjustments with pushbuttons and display
  • Selectable burst mode (RFoG)
  • Automatic laser clipping mitigation
  • Internal WDM filter option
  • Power saving mode
  • Excellent ESD and surge protection
  • Optional PC, tablet or smartphone control via wireless BT or USB (E61 & E62)
  • Optional RIS receiver for remote ingress switch control (E61 & E62)
  • Optional lid sensor and monitoring transmitter (E62)
  • Optional RF power measurement with automatic power save control and automatic alignment (E62)
