TP-LINK MC111CS is reliable media converter enabling the transmission of Fast Ethernet data stream in one single-mode optical fiber over distances up to 20 km. The media converter has one SC connector used to transmit and receive optical signals. It is possible due to the use of wavelength-division multiplexing technology (WDM) - different wavelengths of laser light carry different signals, over one strand of fiber. It significantly lowers installation costs.
The device transmits optical signal in the III transmission window (1550 nm) and receives optical signal in the II window (1310 nm). Sensitivity of the receiver and output power of the transmitter are adapted to transmit optical information up to 20 km.
TP-LINK 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.
TP-LINK media converters are fully compatible with IEEE 802.3, IEEE 802.3u, IEEE 802.3x standards. Their installation is very simple thanks to "Plug and Play" feature. The LED indicators show current operating status.

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 200 km - 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
TP-LINK 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. TP-LINK Ethernet media converters are primarily used to connect building LANs (e.g. of scattered buildings of one corporation). Below there is a sample application of that converters.
