I purchased 2 1000Mbps TX to 1000Base-SX Fiber Converters, TFC-1000MSC. Our fiber line has the old ST connections. So i purchased 2 1m Multimode ST/SC Patch Cable for each end. I plugged both network cables into 1000Mbps switches and i get nothing. the Link/Act is not lit up at all. I made sure i reversed th TX & RX cables like the installation guide says, i reversed them where they plug into the fiber connecters, hope thats right. please help! thanks!
