Connecting Fiber Ports (only for models with fiber port)
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.
These models have two 100Base-FX ports with SC type connectors (in multi-mode and
single mode versions).
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.
