Ethernet media converter ULTIMODE M-407M allows to change electrical signals (Ethernet data stream) coming via typical STP/UTP cable into modulated light signal transmitted via single-mode fiber cable.

Distinguishing features:

ULTIMODE M-407M is reliable media converter set enabling the transmission of Fast Ethernet data stream in two single-mode optical fibers at distances up to 40 km. The media converter has one SC connector used to transmit (Tx) or receive (Rx) the signal. It is possible due to use of wavelength-division multiplexing technology (WDM) - different wavelengths (colors) of laser light to carry different signals, over one strand of fiber. It significantly lowers installation costs. The L11541 set contains two transceivers and two power supplies (12VDC/2A).

One of the devices transmits optical signal in the III transmission window (1550 nm), whereas the second uses the II window (1310 nm). Sensitivity of the receiver and output power of the transmitter is adapted to transmit information up to 20 km. In the case of shorter distances (up to 2 km), it is required to use additional 2dB attenuators by the receivers. They will protect them against "burning".

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 100.000 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.
