This system Provides the Fiber Optic Communication interface between On shore Data logger and Under water mine. This system is based on FPGA, communication and Response is supported through RS-232 I/F with 9600 Baud rate.
This FOIM module consists of three cards
Optical Transceiver Card
It receives the commands from the onshore Data Logger in Optical form with the Speed of 4Mbps and converts the same data into differential electrical form and transmits to FPGA card & vice versa.
Operating Temperature :
-40°C to +85°C.
Distance :
Up to 40Km.
Current drawn :
50mA.
Fiber connector :
SC Duplex.
Fiber cable :
9/125 μm, 1310/1550 nm wave length.
FOIM Card
FOIM receives differential data from Optical Transceiver card and process the data commands to Mines.
Receives Acoustic noise (ANDAC) Differential data of 16 bit and 100K samples. Transmits / Receives RS232 data to / from Mine system.
Power Supply Card
Power supply Card is used to generate 5V DC supply from Input voltage of 18V to 32V DC.
Isolated Power Supply.
Reverse Polarity protected.
Reduce EMI / EMC Noise and Spikes.
MIL-STD-46IC compliance.
