WISI DOCSIS 3.1 Inverted Node 8 Port LC-APC - 230VAC

20MM-LR44L8102

Product Summary

The LR44 inverted node is used for FTTX deployments to accommodate existing HFC plants. The highly integrated optical components allow the smallest footprint for OBI-free RFoG deployments, including optical amplification and high splitting ratios to connect up to 32 ports with options for further internal splits. In addition, this ruggedized housing supports installation in harsh environments like mining camps. With 1.2GHz in the downstream direction and up to 204MHz (electronic switchable diplexer) in the upstream direction providing flexibility, the LR44 is the first choice for innovative forerunners and established operators.
