1000/2500BaseSFP (mini-GBIC) Fiber Port
The Gigabit Ethernet fiber ports on the switch are 1000/2500BaseSFP
fiber ports, which must use 1G or 2.5G mini-GBIC fiber transceivers to
work properly.
The concept behind the LC port and cable is quite straightforward.
Suppose that you are connecting devices I and II; contrary to electrical
signals, optical signals do not require a circuit in order to transmit data.
Consequently, one of the optical lines is used to transmit data from
device I to device II, and the other optical line is used transmit data
from device II to device I, for full-duplex transmission.
Remember to connect the Tx (transmit) port of device I to the Rx
(receive) port of device II, and the Rx (receive) port of device I to the
Tx (transmit) port of device II. If you make your own cable, we suggest
labeling the two sides of the same line with the same letter (A-to-A and
B-to-B, as shown below, or A1-to-A2 and B1-to-B2).
