3405 Frame Manual
3405FR Series Fiber Optic SFP Frame
3405FR Series - 20
Revision 2.3
NOTE: Channels A and B on the front of the 3405FR-BNC frame (Figure 2-14)
correspond to channels A and B on the rear of the frame.
2.7.2. Rear Panel DIN Connections
A group of 4 MiniDINs on the rear of the 3405FR-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 2.6.3.

NOTE: Channels A and B on the front of the 3405FR-DIN frame (Figure 2-14)
correspond to channels A and B on the rear of the frame.
2.7.3. Rear Panel XLINK Connections
The X-LINK IO’s on the rear of the 3405FR-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).

location:
