Ethernetový Media Konvertor ULTIMODE M-207G

Ethernetový media konvertor ULTIMODE M-207G L11525 umožňuje změnu elektrických signálů (Ethernetového toku dat) přijímaného přes klasický STP/UTP kabel do modulovaného světelného signálu přenášeného přes jednomódový optický kabel.

•maximální přenosová vzdálenost - 20 km
•přenos jedním jednomódovým vláknem (WDM)
•LED operační indikátory
•jednoduchá instalace (funkční po zapojení)
•set obsahuje 2 transceivery a 2 kabely pro napájení

ULTIMODE M-207G is reliable media converter set enabling the transmission of Ethernet data stream in two single-mode optical fibers at distances up to 20 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 L11525 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).

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 two single-mode fibers - transmission up to 40km - M-403M L11041
•with one single-mode (WDM) fiber - transmission up to 20km - M-207M L11521 and transmission up to 40km - M-407M L11541
