Should ONLY be used on 10FL series RMC products.
The transparent mode can be utilized when BOTH the copper side and fiber side devices are capable of auto-
negotiating duplex mode and speed as per TIA/EIA-785. When both partners are capable of negotiation, the
RMC can support 100Base-TX to 100Base-SX, full duplex, copper-to-fiber media conversion on 10FL standard
electronics and fiber media. The TIA/EIA-785 standard allows for 10FL communication lines that are less than
300m in length to be upgraded to 100 Mb/s communication links.
The HDX and FDX modes exist to accommodate fiber link partners that are operating in the forced mode. Due
to the high number of forced full duplex fiber optical devices available, the factory default is the FDX, full duplex,
mode.
