Ethernet Media Converter ULTIMODE M-403M

Ethernet media converter ULTIMODE M-403M 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:

•1 x Ethernet 10/100 Mb/s port (RJ-45)
•maximum transmission distance - 40 km
•transmission via two single-mode fibers
•LED indicators showing operating status
•easy installation (plug and play)
•power supply included

ULTIMODE M-403M is reliable media converter enabling the transmission of Fast Ethernet data stream in two single-mode optical fibers at distances up to 40 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.
Sensitivity of the receiver and output power of the transmitter is adapted to transmit information up to 40 km. In the case of shorter distances (up to 4 km), it is required to use additional 2dB attenuators by the receivers. They will protect them against "burning".

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).

NOTICE!! It is not allowed to look directly at the fiber port when the device is plugged. The radiation invisible for the human eye can damage the retina!

Why to choose fiber optics:

•possibility of sending signal over long distances (low attenuation of optical fibers - e.g. for the wavelength of 1550 nm the attenuation is about 0.2 dB per kilometer, which means that the signal can be sent at a distance of 200km - without regeneration)
•high-volume information transfer via single fiber
•resistance to electromagnetic interference
•resistance to weather conditions (humidity, electrostatic discharges and others)
•no tapping possibility
•low weight and small dimensions

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.

The devices are designed for indoor operation. The ULTIMODE series includes a number of types:

•with two multimode fibers - transmission up to 2km - M-023M L10021
•with one single-mode (WDM) fiber - transmission up to 20km - M-207M L11521, M-207G L11525 and transmission up to 40km - M-407M L11541
