Description
Product Introduction
The GE IS200FOSAG1A is a Mark VIe series fiber optic adapter module that provides conversion between electrical and fiber optic signals for Mark VIe control system communication. This I/O pack enables fiber optic connectivity for applications requiring noise-immune, long-distance communication.
The G1A revision provides fiber optic conversion capability with specific hardware configuration. In our field experience, the FOSA provides essential fiber optic connectivity for noise-sensitive installations. For facilities requiring fiber optic conversion, the FOSA provides the necessary solution.

Frequently Asked Questions (FAQ)
Can I hot-swap this IS200FOSAG1A into a running Mark VIe system?
We strongly advise against it. The FOSAG1A has shown unpredictable behavior when inserted into a powered backplane. Schedule a controlled outage, de-energize the rack, and swap it during planned maintenance.
What is the maximum fiber optic distance for this module?
Maximum distance depends on the specific transceivers and cable type. Verify with OEM datasheet for specific distance specifications.
How do I verify this is a genuine GE module?
We source exclusively from GE-authorized liquidations. Our verification includes OEM packaging inspection, serial number cross-check against GE records, and PCB inspection for GE-specific markings.
What is the expected lifespan of this unit?
We see MTBF around 140,000 hours for the FOSAG1A. We have seen these units exceed 15 years in field service.
