2.1.2.3 OIX (Optical Expander Module)
Each OIX Expander module provides the RF interface to up to two HEU units via two 9-pin connectors. Two OIX Expander
modules are installed in each OIU chassis. Up to four OIU units can be hosted by an HEU.
Note: The OIU Expander Modules are similar in appearance to the HEU Expander modules but are NOT
INTERCHANGEABLE. Each Expander module is indicated as RIX or OIX on the bottom of the module.
