Distance Extension
The SBFTF10xx-14x 6-point bridging media converter segments up to four (4)
10Base-T copper Ethernet and/or 100Base-TX copper Fast Ethernet and up to
two (2) 100Base-FX fiber Fast Ethernet collision domains.
In a
half-duplex
Ethernet or Fast Ethernet environment, the SBFTF10xx-14x
media converter extends network distances by
segmenting collision domains
so that the 512-Bit Rule applies separately to each collision domain (see page
9).
In a
full-duplex
Ethernet or Fast Ethernet environment, the SBFTF10xx-14x
media converter extends network distances to the
physical cable limitations
imposed by the selected twisted-pair copper fiber cables (see pages 1 and 2).
Rate Conversion
The SBFTF10xx-14x media converter allows connection of
10Mb/s
terminal
devices on a 10Base-T legacy Ethernet copper network to
100Mb/s
terminal
devices on a 100Base-TX Fast Ethernet copper network and/or to
100Mb/s
terminal devices on a 100Base-FX Fast Ethernet fiber network.
Congestion Reduction
The SBFTF10xx-14x media converter does not forward collision signals or
error packets from one collision domain to another, improving baseline
network performance. In addition, the media converter filters packets
destined for local devices, also reducing network congestion.
Auto-Negotiation
The Auto-Negotiation feature allows the SBFTF10xx-14x media converter to
automatically configure itself to achieve the best possible mode of operation
over a link. The media converter broadcasts its speed (10 Mb/s or 100 Mb/s)
and duplex capabilities (full or half) to the other devices and negotiates the
best mode of operation. Auto-Negotiation allows quick and easy installation
because the optimal link is established automatically.
A scenario where the media converter is linked to a non-negotiating device is
a case where the user may want to
disable
Auto-Negotiation. In this instance,
the mode of operation will drop to the least common denominator between
the two devices (e.g.: 10 Mb/s, half-duplex). Disabling this feature gives the
user the ability to force the connection to the desired speed and duplex mode
of operation.

AutoCross™
When the AutoCross feature is activated, it allows either straight-through
(MDI) or crossover (MDI-X) copper cables to be used when connecting to
10Base-T or 100Base-TX devices. AutoCross determines the characteristics of
the connection and automatically configures the unit to link up, regardless if
the copper cable is MDI or MDI-X configuration. (Transition networks
recommends leaving the device in the default “enable” mode.)
Fiber Redundancy
The SBFTF10xx-14x media converter provides stable and affordable Fiber
Redundancy in highly critical Ethernet and Fast Ethernet segments.
When the Fiber Redundancy feature is enabled, only one fiber connection
(primary) is active at a time. This primary connection is in the forwarding
stage while the other fiber connection (secondary) is put in the disabled state.
When failure on the primary fiber connection occurs, it is detected by a
converter. The secondary connection is activated and becomes the primary
link. The original fiber link is put in the disabled state and becomes
secondary until the failure on primary fiber connection occurs.
