Moxa IMC-21A industrial ethernet-to-fibre media converter

The Moxa IMC-21A industrial ethernet-to-fibre media converter converts from 10/100BaseTx to 100BaseFx and is designed to meet the needs 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) capability. 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.

The IMC-21A series is DIN rail mountable and operates on a 12 to 48 VDC supply. The TP port’s connection speed, half/full duplex mode and force/auto mode are all selectable by DIP switch, as is the fibre port’s half/full duplex mode. Multimode and singlemode models with SC or ST fibre connectors are available.
