4.8.3: MACRO Port (J7-XML/J8-800-1808) 
The XML/800-1808’s duplex SC sockets, shown below, accept standard optical fiber.  
The IN port connects to a master or to the OUT port of a device that is “upstream,” between the 
XML/800-1808 and the master. The OUT port connects to “downstream” nodes. If XML/800-1808 
is the last node on a network, only the IN port is used. No terminator is required on the OUT port.
