The length of the fiber-optic cables shall not exceed 2 km.
Make sure to use the appropriate optical fiber, considering its curvature radius.
For information about optical fiber types and link specifications, see Chapter 17:
Technical Specifications.
When more than one RA333 module is required, an internal module jumper must be
configured, according to the TW link position. The position of links does not have to
be consecutive, but module installation related to A to H position must match the
jumper identification. For example, ID 0 must be the first RA333 (TW) link, ID 1 must be
the second RA333 (TW) link, and so on.
In order to configure these jumpers, remove all connectors and cables which are
connected to the module and remove the back panel of the RA333 removing the 12
screws of the panel and the screw of the protective grounding, as shown in
113.
