BGB Solutions for various GE turbines:

1X – Direct replacement upgrades


Data Lines:

2X – Direct replacement upgrades

Operating Temp: -40C to +80C Optional Heating Cold-Weather Element: Installs

2X - With Fiber Optic Rotary Joints (FORJ)

The FORJ unit offers higher speed data-transfer, a durable stainless steel construction and is not influenced by vibration, humidity, heat or other typical disturbances. In addition, the FORJ is immune to all forms of electrical interference.



Available in 2020 with multiplexer converters retrofitted into existing GE turbines
