enabling an installer to see the LINK (or no-LINK) status of each port and each piece of
cable independently. This is ideal for the installer. But it introduces a discontinuity for
the managed network software which wants to “see through” the media converter and
wants to treat it as part of the cable attached to a particular port.
The Link-Pass-through model, TF14-LP, provides the LINK “see-through”
feature desired for managed networks. On these models, either both LINK LEDs are lit
or neither is lit. And, the TF14-LP operates in transparent half- and full-duplex mode.
The following diagram illustrates the standard condition, no Link Pass-through.
