Installation
Connect the Twisted-Pair Copper Cable
1. Locate or build IEEE 803.2™ compliant 10Base-T or 100Base-TX cables
with RJ-45 connectors installed at both ends.
2. Connect the RJ-45 connector at one end of the cable to the RJ-45 port on
the SBFTF10xx-26x media converter.
3. Connect the RJ-45 connector at the other end of the cable to the RJ-45
port on the other device (switch, workstation, etc.).
NOTE: The AutoCross feature allows either MDI (straight-through) or MDI-X
(crossover) cable connections to be configured automatically, according to the
network conditions.

•Up (half-duplex) - The fiber cable distances are
constrained by the 512-Bit Rule (see page 8).
•Down (full-duplex) - The fiber cable distances are
constrained by the cable requirements (see pages
1 and 2).
Install the Fiber Cable
1. Locate or build IEEE 803.2™ compliant 100Base-FX fiber cable with
male, two-stranded TX to RX connectors installed at both ends.
2. Connect the fiber cables to the SBFTF10xx-26x as described:
• Connect the male TX cable connector to the female TX port.
• Connect the male RX cable connector to the female RX port.
3. Connect the fiber cables to the other device (another media converter,
hub, etc.) as described:
• Connect the male TX cable connector to the female RX port.
• Connect the male RX cable connector to the female TX port.
Power the Media Converter
NOTE: The external power supply provided with this product is UL listed by
the power supply’s manufacturer.
1. Connect the barrel connector on the power adapter to the media
converter’s power port (located on the back of the media converter).
2. Connect the power adapter plug to AC power.
3. Verify that the media converter is powered by observing the illuminated
LED power indicator light.
For DC power, consult the user’s guide for the Transition Networks SPS1872-
xx DC external power supply for powering the media converter.

Product Features
Rate Conversion
The SBFTF10xx-26x 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-26x 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.
Full-Duplex Network
In a full-duplex network, maximum cable lengths are determined by the type
of cables that are used. See pages 1 and 2 for the cable specifications for the
different SBFTF10xx-26x models.
The 512-Bit Rule does not apply in a full-duplex network.
Half-Duplex Network (512-Bit Rule)
In a half-duplex network, the maximum cable lengths are determined by the
round trip delay limitations of each Fast Ethernet collision domain. (A
collision domain is the longest path between any two terminal devices, e.g. a
terminal, switch, or router.)
The 512-Bit Rule determines the maximum length of cable permitted by
calculating the round-trip delay in bit-times (BT) of a particular collision
domain. If the result is less than or equal to 512 BT, the path is good.
For more information on the 512-Bit Rule, see the white paper titled
“Collision Domains” on the Transition Networks website at:
www.transition.com.

Operation -- Continued
Product Features -- Continued
Auto-Negotiation
The Auto-Negotiation feature allows the SBFTF10xx-26x 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, 100 Mb/s,
etc.) 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. No user
intervention is required to determine the best mode of operation.
AutoCross™
AutoCross feature allows either straight-through (MDI) or crossover (MDI-X)
copper cables to be used when connecting to 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.
Pause
The Pause feature is used to temporarily suspend data transmission in order to
relieve buffer congestion. If a media converter needs some time to clear
network congestion, it will send a pause signal to the media converter at the
other end, which will wait a predetermined amount of time before re-
transmitting the data. This feature reduces data bottlenecks, allows for a more
efficient use of the network devices, and prevents the loss of valuable data.
This feature reduces data bottlenecks, allows for a more efficient use of the
network devices, and prevents the loss of valuable data.
Far End Fault
When a fault occurs on an incoming fiber link (1), the media converter
transmits a Far-End Fault signal on the outgoing fiber link (2). In addition the
Far-End Fault signal also activates the Link Pass-Through, which, in turn,
disables the link on the copper portion of the network (3) and (4).
