The Optospider™ DMMC 520nm duplex 10Mbps media converter was developed for long distance data links with a link length of 80m to 250m. The typical handling and installation advantages of polymer optical fiber (POF) cables are applicable now for transmission distances that are considerably longer than available POF systems.

Today's 100Mbps POF systems use 650nm red LED and socalled 4B5B coding scheme. These systems are distance limited to about 120m due to signal dispersion on the POF cable. A further distance limit is the rather high POF attenuation of 16.5dB/100m in the red window at 650nm.

The new developed Optospider™ DMMC 520nm duplex 10Mbps system overcomes these limitations by:

• the data rate reduction from 100Mbps to 10Mbps removes the signal dispersion problem for distances up to 250m, because the signal pulse length is increased from 8ns to 50ns (Manchester coding),
• the low data rate allows the use of green LED with a wavelength of 520nm instead of 650nm and reduces thus the signal attenuation from 16.5dB/100m to 8dB/100m at 520nm.
