INSTALLATION
Installing the Cable
FIBER
1.
Locate or build fiber cable with male, two-stranded TX to RX connectors
installed at both ends.
2.
Connect the fiber cables to F-SM-MM-04 Media Converter as described:
•
Connect the male TX cable connector 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 the female RX port.
•
Connect the male RX cable connector to the female TX port.
Connect the fiber cable
to the Media Converter
as shown.

Full-Duplex Network
In a full-duplex network, maximum cable lengths are determined by the type
of cables that are used. See page 4 for the cable specifications for the
different F-SM-MM-04 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:
