FO media converter

It isn’t possible to lead high bit rate signals into a shielded area by using conventional filtering measures. The necessary pass band for the signals would significantly degrade the shielding effectiveness of the faraday cage. To overcome this challenge, FO (fibre optic) converters have been designed. The basic function of all types of converter is similar. The information is converted into an optical signal and transmitted galvanic isolated via an optical fibre into the shielded area. Finally the optical signal is converted back into the original electrical signal. To avoid the generation of RF noise in the shielded area, the inside converter is RF shielded. There are a considerably high number of products available; however, the solution & components shown below is the most commonly used by Albatross Projects. basic design Features uni-/bidirectional data transfer immunity of the EMC hardened satellite: 200V/m up to 18GHz compact housings of both units 8 hours continuous operation housing is approx. 230mm x 170mm x 90mm FO Converter – basic layout LAN converter Introduction about LAN LAN (local area network) is a computer network that spans a relatively small area, capable of transmitting data at very fast rates, much faster than data can be transmitted over a telephone line. The foEthernet is a bidirectional fibre optic link for Ethernet conforming signals (IEEE 802.3). This system consists of 2 units connected via a duplex fibre optical cabling. Features FO-transmission for Ethernet-Interface immunity of the EMC hardened satellite: 200V/m up to 18GHz bidirectional data transfer with rate either 10Mbit/s or 100Mbit/s or 1Gbit/s both satellites shielded GPIB converter Introduction about GPIB The General Purpose Interface Bus (GPIB) was invented by Hewlett Packard at the end of the 1960's. The intention was to create a reliable bus system especially designed for connecting computers and instruments. The foGPIB is a bidirectional. This system consists of 2 units connected via a duplex fibre optic cable. Features FO-transmission for GPIB (IEEE 488.1) bidirectional data transfer, data signal rate up to 2,2MByte/s immunity of the EMC hardened satellite: 200V/m up to 18GHz both satellites shielded RS 232 converter Introduction about RS232 In the early 1960s, a standards committee, today known as the Electronic Industries Association, developed a common interface standard for data communications equipment. From these ideas, the RS232 standard was born. It specified signal voltages, signal timing, signal function, a protocol for information exchange, and mechanical connectors. The most recent modification by the Electronic Industries Association being the EIA232E standard, introduced in 1991. Features bidirectional data transfer, data signal rate up to 115kBaud immunity of the EMC hardened satellite: 200V/m up to 18GHz compact housings of both units 14 hours continuous operation both satellites shielded VGA converter Introduction about VGA Video Graphics Array (VGA) is a computer display standard first marketed in 1987 by IBM as MCGA. VGA belongs to a family of earlier IBM video standards and largely remains backward compatible with them. VGA can be seen as an enhancement of and successor to the previous EGA and CGA graphics adapters.. Features unidirectional data transfer (PC to monitor), bandwidth 80MHz immunity of the EMC hardened satellite: 200V/m up to 18GHz EMC hardened, compact housings of both units one satellite shielded USB converter Introduction about USB The foUSB is a fibre optic link for transmission of USB signals and consists of 2 units connected via a duplex fibre optical cable. The foUSB (Transmitter) transforms the electrical USB signal into an optical signal and transmits it via fibre optic. Finally the foUSB (Receiver) receives the optical signals and transforms it back into the electrical USB signal. The Transmitter must be connected to a PC (Host), on Receiver side you can connect it to any type of USB device. Features unidirectional data transfer (PC to monitor), speed up to 480Mbit/s immunity of the EMC hardened satellite: 200V/m up to 18GHz EMC hardened, compact housings of both units one satellite shielded
