Wiring the Fiber Ports ( JetNet 3705f series)
The automatic MDI/MDI-X crossover function does not apply to fiber connections, as these must
be crossed over manually. To connect the fiber port on one switch to the fiber port of another
switch, simply cross-connect the transmit channel at each end to the receive channel at the
opposite end as illustrated in the figure below.
JetNet 3705f Series have one 100Base-FX port with SC type
connector (in multi-mode and single mode versions). Single-mode
types have greater distance capability than multi-mode types, but
single mode cable is generally more expensive.
A fiber segment using single-mode cable must use 9/125 or 10/125
micrometer single-mode fiber cables. For single-mode, the
connection distance can be up to 30 km.
A fiber segment using multi-mode must use 50 or 62.5/125
micrometer multi-mode fiber cables. For multi-mode, the connection
distance can be up to 2 km.
