Introduction
ADAM-6541 is designed to convert Ethernet networks to fiber networks. It does so by transparently converting Ethernet signals to optic signals. The advantages of fiber optics are wide bandwidth,
EMI immunity and long-distance transmission capability. Therefore, ADAM-6541 is an ideal solution for “fiber to building” applications at central offices or local sites.
ADAM-6541 supports MDI/MDIX auto detection, so you don’t need to use crossover wires. It also includes a switch controller that can sense the transmission speed (10/100 Mbps) automatically.
Both the Ethernet port and the fiber port have memory buffers that support store-and-forward mechanisms. This assures data can be transmitted properly.
ADAM-6541 is extremely compact and can be mounted in three different ways: DIN-rail, Wall and Stack. ADAM-6541 can work normally from 0 ~ 60 °C and accepts a wide voltage range from
+10 ~ 30 V
DC
. Besides, it also provides 3,000 V
DC
surge (EFT) protection against over-voltage, so it is suitable for harsh operating environments.
Link Fault Pass-Through (LFP)
ADAM-6541P/6541S is an enhanced Ethernet to fiber-optic converter. Aside from its standard features, the versatile ADAM-6541P/6541S also has the LFP (Link Fault Pass-through) feature.
When one side of the link fails, the other side continues transmitting packets, and waiting for a response that never arrives from the disconnected side. Use the internal jumper to enable the LFP
function, then ADAM-6541P/6541S will force the link to shut down as soon as noticed that the other link has failed, giving the application software a chance to react to the situation.
