TP Connection When using the FC Outlet RJ-45, the
following cable lengths are permitted:
100 m for standard cable
85 m for trailing cable
85 m for marine cable
Note
The number of ELS switches connected influences the frame propagation time.
When a frame passes through the ELS, it is delayed by the Store&Forward func-
tion of the switch.
-
with a frame length of 64 bytes by approximately 10 µs
- with a frame length of 1500 bytes by approximately 130 µs
This means that the more ELS switches the frame passes through, the longer the
propagation time.
