Distinguishing features:

ULTIMODE M-023M is reliable media converter enabling the transmission of Fast Ethernet data signal in two multimode optical fibers at distances up to 2 km. The media converter has two SC connectors used to transmit (Tx) or receive (Rx) the signal. Optical signal is transmitted and received in the second transmission window of 1310 nm.

ULTIMODE devices have MDI/MDIX auto detection feature and automatically find and set the fastest connection speed and mode. "Store and forward" mechanism allows to verify the received data using checksum function.

ULTIMODE media converters are fully compatible with IEEE 802.3 and IEEE 802.3u standards. Their installation is very simple thanks to "Plug and Play" feature. The LED indicators show current operating status. Durable laser diode with Fabry-Perot resonator ensures the mean-time-between-failure (MTBF) at least of 100000 hours (more than 11 years).

ULTIMODE media converters are widely used for the transmission of Ethernet signals over long distances and in areas exposed to harsh weather conditions. Optical fibers provide full electrical insulation and resistance to electromagnetic interference. Media converters are primarily used to connect building LANs (e.g. of scattered buildings of one corporation). Below there is a sample application of ULTIMODE converters.
