WISI 27-65V AC Remote Powered Fibre Optic Receiver High Output 109dBμV - 85-1218MHz

20MM-LR276612

Product Summary

The LR276612 is a high output (109dBuV) remote powered fibre optic receiver with a waterproof and RF-screened die-cast housing. The LR27 is perfect for use in harsh environments such as pedestals and other types of outdoor enclosures. Two way tapped or split output available by using XM25B0044 (4dB/4dB), XM25B0082 (8dB/2dB) and XM25B0131 (13dB/1dB) (sold separately). 14MM-ZG28 required to adapt to 'F' type outputs or 14MM-ZG01 for 5/8 output. Bluetooth control using Android devices for easy setup. (14MM-LB01 antenna required, sold separately.)

Features and Benefits

  • Remote powered by 27-65V AC for those pit and riser locations where 230V is not available
  • All settings (gain, slope etc.) via WISI Bluetooth app or by OH41 hand controller
  • Pluggable output splitters/taps for flexible configuration of the two RF outputs (sold separately)
  • Optical ALC for regulated output levels - high output level of 109dBuV for a full DOCSIS 3.1 load in FTTC or FTTB networks with built-in WDM for the upstream signal to allow use on a single fibre core.
  • DOCSIS-3.1-compliant frequency range: downstream up to 1.2 GHz, upstream up to 204 MHz (depending on diplexer)
  • IP66 rated with operating temperature range -20 to +55°C
