Product Description

Multimode Converter

The following fiber optic converters have been designed for the distribution of electrical signals over distances of up to 2,000 mtrs. The optical ST connectors are linked via an optical GI50/125 µm or GI62.5/125 µm multimode fiber (wave lenght: 850 nm). The launchable optical output power is typ. 20 µW per output, the minimum optical input level is 3 µW. The elecrical inputs and outputs are provided via female BNC connectors or 9pin SubD connectors. If necessary, the output signals of the digital modules can be inverted against the respective input signal by a jumper inside the aluminium profile housing (71 mm x 84 mm x 24 mm / width x depth x height).

The voltage supply (20 - 60 V DC) is provided by a plug-in power supply unit (100 - 240 V AC_IN; 24 V DC_OUT) included in the scope of delivery. All converter variants are equipped with a fixing clamp for 35 mm DIN mounting rails.

Singlemode Converter

Multimode converters are unsuitable to bridge distances over 2,000 m. The following singlemode converters were developed to distribute electrical signals over distances of up to 10 kilometers. The optical ST plug connectors are wired via an E9/125 µm mono-mode fiber (wave-length: 1310 nm). The optical output power is typ. 15 µW (-18 bBm) per output and the optical input has a susceptibility of -30 dBm. The electrical in- and outputs are led out via a BNC socket or a D-Sub9 connector.

Even with these modules, the output signal can be inverted against the input signal, if necessary.
