INSTALLATION
NOTE: Channels A and B on the front of the 3505FR-BNC frame (Figure 2-5)
correspond to channels A and B on the rear of the frame.
2.6.2. Rear Panel DIN Connections
A group of 4 MiniDINs on the rear of the 3505FR-DIN are fixed and correspond to a particular SFP
module. These BNC MiniDINs are agile and are assigned as inputs or outputs depending on the type of
SFP inserted. For detailed input and output assignments, please see section 2.5.3.

NOTE: Channels A and B on the front of the 3505FR-DIN frame (Figure 2-5)
correspond to channels A and B on the rear of the frame.
2.6.3. Rear Panel XLINK Connections
The X-LINK IO’s on the rear of the 3505FR-XLINK are fixed and correspond to a particular SFP
module. This X-LINK connector is agile and thus configured as inputs or outputs. An X-LINK connector
will become an electrical input if its corresponding SFP spigot is an optical transmitter (Electrical to
Optical converter). Conversely the X-LINK connector will become an electrical output if its
corresponding SFP spigot is an optical receiver (Optical to Electrical converter).
