CONFIGURATION SWITCH:
One switch has been provided to allow the fiber port to be
configured for half or full duplex. The default position is Full
Duplex. The 100Base-FX standard does not provide for fiber duplex
negotiation. Therefore, this switch provides the user with the
ability to control the Duplexing option as may be required in
certain network configurations.
NETWORKING ISSUES:
FULL DUPLEX -- Fiberdyne Labs, Inc. 10/100BASE-TX to 100BASE-FX
Two Port Switch can help solve your Fast Ethernet distance
problems. In a full duplex environment the standard multi-mode
product will support fiber segments up to 2km. (Your network
equipment must support full-duplex, non-shared operation. (i.e.
Full duplex network cards connected to switches or routers; not
hubs.) A single-mode variant supports distances up to 15km in a
full-duplex environment.
HALF DUPLEX -- Half-duplex, or Carrier Sense
Multiple Access / Collision Detection (CSMA/CD) network distances
are limited by the 512 bit time limit for the two most distant
nodes. As a consequence of this, the maximum fiber segment in a
half duplex network is only about 412 meters.
CROSSOVER CABLES -- CAT 5 crossover cables are
required when connecting the switch to another switch, or
hub.
