7. Cable Connection Parameter
Fast Ethernet 100Base-FX networks allow 512bit time delay
between any two-node stations in a collision domain.
The overall bit time of Fiber wires and devices must be within
512bit time in segment. To extend the distance, you may use
switch to break up a collision domain and extend the distance.
The limitations are as below:
Duplex
Connection
Limitation (max.)
Multi-Mode
MM Half
Node to Node
Node to Switch
412 meters*
MM Full
Node to Node
Node to Switch
2 kilometers
Single-Mode
SM Half Node to Node
Node to Switch 412 meters*
SM Full
Node to Node
Node to Switch
Varies on model
Note:
n
In half-duplex mode, 412 meters is the maximum distance
between two devices. To force both devices to full-duplex
for optimal distance is strongly recommended.
