Multi-Modular I/O System
A-Net Via Fiber
When an optional single- or multi-mode fiber optic SFP (Small Form-factor Pluggable ) transceiver is installed in
either the A or B fiber port, the matching RJ45 Cat-5e port is disabled. When both fiber ports are in use, A-Net
data to both Cat-5e ports is disabled but the Power Over A-Net (PoA) feature is still usable as a means of powering
the F6 Modular I/O Frame.

Always power down the F6 Modular I/O Frame before installing or removing SFP fiber optic transceivers
to avoid damaging the SFP transceiver and/or F6 electronics.

Each pair of Cat-5e and Fiber ports (A and B) are linked.
Using fiber connectivity increases the usable maximum distance between Pro64 devices in a network beyond
what standard Cat-5e cabling can provide. The actual distances that can be achieved are dependent upon the
type of fiber cabling used (single- or multi-mode), the number of junctions, patch points and connections made
in the fiber run itself, plus the power budget and light handling specifications of the SFP transceivers used.
SFP transceivers used with Pro64 devices should be capable of working with Fast Ethernet data rates (up to 155
Mbps); many Gigabit Ethernet SFP transceivers (up to 1.25 Gbps) are capable of working with Fast Ethernet data
rates as well.
Consult the SFP transceiver manufacturer’s product specifications to determine if a particular SFP transceiver is
appropriate for the application.

When fiber connectivity is not required for an application, the SFP transceivers should be removed from
the F6 to enable the Cat-5e ports.
Optical Transceiver Safety
Observe the following guidelines when using SFP transceivers with your Aviom product.
An SFP is a Class 1 laser product. Avoid exposure to laser radiation and do not stare into open fiber apertures
when no fiber cable is connected.
SFP transceivers are sensitive to ESD (Electrostatic Discharge). Wear an ESD-preventive wrist strap that is connected
