The integrated Optical Distribution Unit (iODU) receives downlink RF signals from the integrated BTS Interface Unit (iBIU), converts the RF signals to optical, then sends the signal to the remote optic units (ROUs) or to the Optic Expansion Unit (OEU or iOEU) via fiber optic cabling. This process is reversed for the uplink path. The iODU is typically co-located with the BTS Interface Unit (iBIU) from which it receives power and RF communication via two coax cables and a power cable. The iODU is equipped with a fan unit for improved heat dissipation. This design feature allows the operator to stack multiple iODUs to conserve rack space. • RF to optical / optical to RF conversion • Single strand per ROU or OEU • Modular design - up to 8 optical ports • Single mode SC-APC c°nnecti°n • 5 or 10 dBo link budget to ROU or OEU • Compact form factor (1RU) - 19” rack mount Version 1.4 - April 2023 ©SOLiD.
