5. WDM Single Fibre Model
The POE100 Series media converter has an optional Wavelength Division
Multiplexing (WDM) Model that can transport bi-directional full duplex signals
over a single fibre simultaneously.
Single Fibre Model TX, RX Wavelength
TX (Transmit) 1310nm 1310nm Single Mode 20Km
RX (Receive) 1550nm
TX (Transmit) 1550nm
1550nm Single Mode 20Km
RX (Receive) 1310nm
Note:
The 1310nm and 1550nm models must be installed in pairs,
i.e., install 1310nm model at one end and the 1550nm model at the other end.
6. Link Failure Propagation
The POE100 Series media converters support Link Failure Propagation (LFP).
If the Copper port is unplugged, the converter stops transmission on the fibre
port. This causes the remote fibre node link to fail as well. The LED’s on the
converter will now show link failure on both the copper and fibre ports. If the
fibre link fails, the converter restarts auto-negotiation on the copper port but
always stays in the link failure state. This causes the remote copper node link
to fail as well. The LED’s on the converter will now show link failure on both
the copper and fibre ports.
Refer to Fig. 7 shown below for the normal status when link is active. Also
refer to Fig. 8 and Fig. 9 for the LED status when copper Cable A, Fibre Cable
B or Fibre Cable C fails.
Note:
The Link Failure Propagation (LFP) function only take effect when S1-Bit4
(see Fig. 10) is enabled. When S1-Bit4 is disabled the media converter will
function normally.
