Introduction
Transition Networks SBFTF10xx-10x 2-port Ethernet/Fast Ethernet bridging media converter connects
10Base-T Ethernet or 100Base-TX Fast Ethernet twisted-pair copper network devices to network devices
on a 100Base-FX Fast Ethernet fiber network.
The SBFTF10xx-105 provides an interface between 10/100Base-TX ports and 100Base-FX ports, allowing
users to integrate fiber optic cabling into 10/100Base-TX copper environments. Operating at Layer 2,
this converter not only converts copper to fiber, but it also does Rate Conversion, converting 10/100
copper to 100Base fiber.

Page 3: Installation
Transition Networks SBFTF10xx-10x User Guide Installation CAUTION: Wear a grounding device and observe electrostatic discharge precautions when setting the 6-position DIP switch. Failure to observe this caution could result in damage to the media converter. Set the 6-position DIP Switch The 6-position switch is located located on the side of the media converter. -
Page 4: Connect The Twisted-Pair Copper Cable
Transition Networks SBFTF10xx-10x User Guide Connect the Twisted-Pair Copper Cable Ensure that the correct cable type is installed to support the highest speed and mode of operation to be selected. Although Category 3 cable is adequate for the 10Base-T installation, Category 5 cable is strongly recommended, since Category 3 cable can not be used for 100Base-TX installation. -

Transition Networks SBFTF10xx-10x User Guide Product Features Rate Conversion The 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. - Page 7 Transition Networks SBFTF10xx-10x User Guide Distance Extension The SBFTF10xx-10x media converter segments 10Base-T copper Ethernet and/or 100Base-TX copper Fast Ethernet and 100Base-FX fiber Fast Ethernet collision domains. In a half-duplex Ethernet or Fast Ethernet environment, the SBFTF10xx-10x media converter extends network distances by segmenting collision domains so that the 5-Segment Rule or the 512-Bit Rule applies separately to each collision domain.

Page 9: Half-Duplex Network
Transition Networks SBFTF10xx-10x User Guide Half-Duplex Network 512-Bit Rule – 100Base-TX or 100Base-FX Use the 512-Bit Rule to calculate the 100Base-TX or 100Base-FX half-duplex collision domain. In a half-duplex network, the maximum cable lengths are determined by the round trip delay limitations of each Fast Ethernet collision domain. - Page 10 Transition Networks SBFTF10xx-10x User Guide 100Base-TX fiber Example The drawing below illustrates a collision domain where two media converters are connected via fiber cable. Since the total of the bit-times in this example is less than 512 (50BT + 400BT + 50BT = 500BT) the path is good.
- Page 11 Transition Networks SBFTF10xx-10x User Guide 10Base-T Twisted-pair Example The example below illustrates below applying the 5-Segment Rule. The cable between each network device (media converter, Hub, or Terminal) is numbered as a “segment”. Note that the longest transmission path (from the media converter at the top to the terminal at the bottom) is 5 segments.
