June 17, 2011—Moxa unveiled the IMC-21A, a new series of industrial Ethernet-to-fiber media converters. The IMC-21A converts from 10/100BaseT(X) to 100BaseFX and is designed to meet the demanding requirements of critical applications: it can operate reliably and stably in a wide temperature range of -40 to 75°C and is housed in a rugged metal case.
To prevent data transmission failures, the IMC-21A series includes Link Fault Pass-through (LFP). Typically, when one side of a link fails, the other end of the link continues to transmit packets, waiting for a response that will never arrive. LFP forces the link to shut down as soon as it notices that the other link has gone down, giving the application software a chance to react.
