Functional Description
The Fiber Optic Node, FON, is a bi-directional electrical/optical signal converter and a
node in either a wire network or a fiber network. It has also functionality for:
– Electrical and optical signal supervision.
– Internal and external alarm handling.
– RS232 interface for local PC control via an O&M software (OM-Online).
– Remote control via an O&M software (OM-Online or OMS).
– Interface for RCC.
– Interface for WLI, wire network.
– Interface for FLI, fiber optic network.
– Battery backup with charger.
The FON unit can be installed in all Powerwave repeaters, remote hubs, and radio heads.
This section contains a description of the FON unit, including block diagram, RF paths,
IP path, R2R communication, FON as gateway node, alarm handling, power, and
backup power.
