Fiber Mode
When the IXF1104 MAC is configured for fiber mode, the TX Data path from the MAC is an
internal
10-bit interface as described in the IEEE 802.3z specification. It is connected directly to an
internal SerDes block for serialization/deserialization and transmission/reception on the
fiber medium to and from the link partner.
The MAC contains all of the PCS (8B/10B encoding and 10B/8B decoding) required to
encode and decode the data. The MAC also supports auto-negotiation per the IEEE 802.3z
specification via access to the

When configured for fiber mode, the full set of Optical Module interface control and status
signals is presented through re-use of GMII signals on a per-port basis (see

While the MAC supports auto-negotiation functions, the IXF1104 MAC does not
automatically configure the MAC or other device blocks to be consistent with the auto-
negotiation results. This configuration is done by the user and system software.
