Installation -- Continued

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.

10Base-T / Ethernet collision domain

•If half-duplex cable is used, refer to the 5-Segment Rule (page 10) before installing the 10Base-T twisted-pair copper cable.

•If full-duplex cable is used, the 5-Segment Rule does not apply. The cable lengths are constrained by the cable requirements (see pages 1 and 2).

100Base-TX / fast Ethernet collision domain

•If half-duplex cable is used, refer to the 512-Bit Rule (page 10) before installing the 100Base-TX twisted-pair copper cable.

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.

Auto-Negotiation

The Auto-Negotiation feature allows the SBFTF10xx-10x 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.)

Link Pass-Through

The Link Pass-Through feature allows the media converter to monitor both the fiber and copper RX (receive) ports for loss of signal. In the event of a loss of an RX signal (1), the media converter will automatically disable the TX (transmit) signal (2), thus, “passing through” the link loss (3). The far-end device is automatically notified of the link loss (4), which prevents the loss of valuable data unknowingly transmitted over an invalid link.

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 (see page 10) or the 512-Bit Rule (see pages 9 and 10) applies separately to each collision domain.

In a full-duplex Ethernet or fast Ethernet environment, the SBFTF10xx-10x media converter extends network distances to the physical cable limitations imposed by the selected copper and fiber cables (see pages 1 and 2).

Congestion Reduction

The SBFTF10xx-10x 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.

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. (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.

To calculate the round-trip delay for a collision domain:

	1.	Find the collision domain, i.e. the longest
		path between any two terminal devices	Class I hub	140 BT
		(e.g., terminal, switch, and/or router).	Class II hub	92 BT
	2.	Calculate the round-trip delay in bit-	terminal/router	50 BT
		times for each length of cable.	1 meter TP cable	1.11 BT
			1 meter fiber cable	1 BT
	4.	Determine the bit-time values for each
			Fast Ethernet switch	50 BT
	3.	device (see table to the right).	SBFTF10xx-10x	50 BT
		Add the bit-time values for each length of

cable and the bit-times for each device.

NOTE: The 512-Bit Rule applies separately to each collision domain.

100Base-TX Twisted-Pair Example

In the example below, the SBFTF10xx-10x 2-Port bridging media converter acts as a switch. In this case, the collision domain bound by the media converter on one end and a terminal on the other.

		100 meters TP	10 meters TP			10 meters TP
		cross-over	cross over		straight-through
		= 111BT	= 11.1BT				= 11.1BT
			class II hub		class II hub
			= 92BT		= 92BT		terminal
							= 50 BT
media converter
	= 50BT

Since the total of the bit-times in this example is less than 512 (see chart below), the path is good.

Sum of the bit-times for the example collision domain:

Media converter		=	50.0	BT
100 m TP cable	(100m x 1.11 BT/m)	=	111.0	BT
Two Class II hubs	(2 x 92)	=	184.0	BT
Two 10 m TP cables (2 x 10m x 1.11 BT/m)		=	22.2	BT
Terminal		=	50.0	BT
Total		=	417.2	BT

Half-Duplex Network -- Continued

100Base-TX Fiber Example

The drawing to the right 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.

400 meters fiber cable = 400BT

media converter	media converter
= 50BT	= 50BT

5-Segment Rule - 10Base-T

Use the 5-Segment Rule to calculate the 10Base-T half-duplex collision domain.

The 5-Segment rule states that a transmission path of a collision domain can consist of no more than 5 segments. A “collision domain” and a “segment” are defined as follows:

A collision domain is the longest path in a 10Base-T network between any two terminal devices, e.g. a terminal, switch, or router. The SBFTF10xx-10x media converter is also a terminal device.

A segment is a cable connection between any two network interfaces within a collision domain.

10Base-T Twisted-Pair Example

The example to the right illustrates 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. Therefore, the network in this example complies with the 5-Segment Rule.

NOTE: The 5-Segment Rule must be applied separately to each 10Base-T collision domain.
