WDM Single Fibre Model | Alloy Computer Products POE100 Series

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
1310nm Single Mode 20Km	TX (Transmit) 1310nm
	RX (Receive) 1550nm
1550nm Single Mode 20Km	TX (Transmit) 1550nm
	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.
