Energy Storage and Signal Integrity
The GE IS200FOSAG1A IS200FOSAG1AAA stores energy using two tantalum capacitors. These capacitors filter power supply noise for the optical transceivers. Each channel operates independently without electrical crosstalk between lines. Consequently, this board achieves complete galvanic isolation up to 10 kilovolts.
Installation and Fiber Routing
You will find four ST female ports arranged on the board’s front panel. Each port accepts standard multimode fiber cables with ceramic ferrules. The board also includes four mounting holes for secure rack attachment. Thus, it fits seamlessly into any standard Mark VIe I/O slot.
