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 Section 2.7 of the Specifications Chapter
17.
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 Figure 112.
