When using a DMC-920R that the TX(transmit) is 1310µm
and the RX(receive) is 1550µm, then the other end need to
have a combination of DMC-920T that the TX(transmit) is
1310µm and the RX(receive) is 1550µm.
The TX needs to connect to the other end’s RX with the same
wavelength.
Media Converter # 1
Media Converter # 2
There is a two pin DIP switch on the module which define as
switch 1 and switch 2:
Switch 1: Fiber mode switch
When the switch was turned to “On”, it means that the fiber
was turned to forced mode, and “Off” for auto-negotiation
mode.
Note: Be sure the opposite end is using the same setting(forced or
Auto-negotiation). And when using two converters at the same
time, the two converters MUST set to forced mode.
Switch 2: LLR
When the switch was turned to “On”, it means that the
LLR was enabled and “Off” for disabled.
Note: When using two converters at the same time, then only one
converter need to enable the LLR function.
