Multi-Modular I/O System
Installing SFP Fiber Transceivers
There are two sets of A-Net ports on the top face of the F6—two copper (Cat-5e, Cat-6) ports and two 100 Mbps
fiber optic ports (requires optional SFP transceivers not included with the F6). Only two A-Net ports can be active
at a time; these can be mixed and matched in any of the four combinations shown below:
A-Net Port A A-Net Port B
Cat-5e Cat-5e
Cat-5e Fiber
Fiber Cat-5e

: Always power down the F6 Modular I/O Frame before installing or removing SFP transceivers.
The F6 only checks for installed SFP transceivers at power-up. Any A-Net port (A or B) with an SFP installed will
have its corresponding copper Cat-5 port disabled. When the F6 Modular I/O Frame detects an installed SFP
transceiver at power-up, it places the corresponding copper port and its PHY chip in a lower power state, even if
no fiber cables are connected.
Though it can’t be used for a Pro64 network connection, the AllFrame can be powered through A-Net port B
when an SFP transceiver is installed in port B.
SFP Transceivers
Small form-factor pluggable (SFP) is a specification for a series of modular, physically compact optical transceivers.
The two 100 Mbps SFP format fiber optic ports on the F6 Modular I/O Frame allow the user to connect optional
single-mode or multi-mode fiber optic transceivers that can transmit Pro64 A-Net data over longer distances
than Cat-5 based cabling can provide.
The SFP fiber optic transceiver is shown with its dust cap on (left) and from the front (right) with its transmit and receive
connectors exposed.
When connecting Pro64 devices via fiber, always use the same type of SFP transceiver in each unit—for example,
use a 100 Mbps single-mode SFP transceiver with the same light wavelength specifications in each device. You
cannot connect a multi-mode fiber transceiver to a single-mode transceiver.
Always leave the optical transceiver’s dust cap on when the SFP transceiver is not in use to avoid damage to the
internal optical connections.
