I just bought a TP-Link MC200CM GBit Ethernet (1000-T) to Fiber (1000-SX) media converter.
The device works but I'm unhappy with the performance: When connecting my computer over 1000-T (twisted pair, Cat 6, 18meters) with my server, I get a throughput of about 610MBit/s. If I replace the cable with two media converters, I'm left with about 310-315MBit/s (i.e. half the performance).
My setup is like this:
Computer <-> GBit switch <-> long cable <-> GBit switch <-> server
Computer <-> GBit switch <-> MC200CM <-> 30m fiber <-> MC200CM <-> GBit switch <-> server
Is there a way to improve the performance? Will another MC be faster? Or is that about as much as I can expect with the additional 2 converters?
