Connecting the Optical Fiber
The Fiber Optical link architecture supports PTP and SFR
mode for different purposes.
1. PTP Mode (Peer to Peer)
The PTP (Peer to Peer) mode provides connection between
2 nodes. When working on this mode, JetCon 2401
can transmit data and receive it at same time, which
means JetCon 2401 is working at full duplex mode.
2. SFR Mode (Serial Fiber Ring)
To extend the transmission distance and to save
the fiber cable cost, JetCon 2401 can link to each
other as a ring architecture, in this mode
JetCon 2401 only provides half duplex
transmission and all of data communication is
controlled by the host device. The maximum of
communication nodes can up to 20.

Note: To ensure your fiber converter transmission/receiving of data between the 2 nodes, the
attenuation of the optical fiber cable should be smaller than the fiber converter's Link Budget.
