The concept behind the LC port and cable is quit e st raightforw ard.
Suppose t hat you ar e connect ing devices I and I I ; contr ary t o elect r ical
signals, opt ical signals do not require a circuit in or der to t ransm it dat a.
Consequently, one of t he opt ical lines is u sed t o t ransm it dat a from
device I t o device I I , and t he ot her opt ical line is used t ransm it dat a
from device I I t o device I , for full- duplex t r ansm ission.
Rem em ber t o connect t he Tx ( t ransm it ) port of device I to t he Rx
(receive) port of device I I , and the Rx ( receive) port of device I to the
Tx ( t ransm it ) por t of device I I . I f you m ake y our ow n cable, we su ggest
labeling the t wo sides of t he sam e line with t he sam e let t er (A- to- A and
B- t o-B, as shown below , or A1- to- A2 and B1- t o- B2) .
