DS3800NFMC1F1E | OEM GE Speedtronic Fiber Optic Master

Description

Product Introduction

The DS3800NFMC1F1E is the aerospace-grade version of the fiber optic master controller—the board GE built for installations where failure isn’t just expensive, it’s unacceptable. The “E” suffix tells the story: aerospace-grade components rated for -55°C to +125°C, triple-layer conformal coating with ceramic-reinforced topcoat, radiation-hardened electronics, and MIL-STD-810G certification with 15g RMS vibration tolerance. This board does the same job as the base NFMC—managing and routing multiple fiber optic links—but it does it in environments that destroy standard boards.

The ceramic-reinforced topcoat provides abrasion resistance—critical when boards are installed in tight cabinets where tools or cables might contact the PCB. The radiation hardening protects against high-altitude and space-adjacent environments (think high-altitude balloon platforms or avionics). Compare this to the NFMC1F1D (military-grade, triple-layer coating, 75g shock/8g vibration). The 1F1E adds radiation hardening, the ceramic topcoat, and higher vibration tolerance.

Frequently Asked Questions (FAQ)

What makes the “E” suffix different from the “D”?
The “E” adds radiation hardening (100 krad), a ceramic-reinforced topcoat for abrasion resistance, and higher vibration tolerance (15g RMS versus 8g). The “D” is military-grade; the “E” is aerospace-grade. The “E” also includes radiation event logging—the “D” doesn’t have this feature. If you’re in a high-altitude, avionics, or radiation-prone environment, you need the “E.” If you’re in a standard industrial or military ground installation, the “D” is sufficient.

What’s the ceramic-reinforced topcoat?
The third layer of conformal coating contains ceramic micro-particles that resist scratching and abrasion. This protects the board during maintenance in tight cabinets where tools or cable bundles might contact the PCB. The ceramic topcoat also provides slightly better salt-spray resistance. The “E” variant has this; the “D” variant does not.

What’s the Radiation Event LED?
The Radiation Event LED indicates that the board has detected a radiation-induced error. The board uses error-correcting memory to recover from single-event effects. If the LED is illuminated, the board experienced a radiation event—it’s informational only; the board continues to operate. The radiation event is also logged for later review.

Do I need to upgrade my DMP firmware for the radiation event logging?
The radiation event logging requires DMP firmware v4.0 or later. Older firmware won’t recognize the radiation event registers—the board will still work, but the Radiation Event LED won’t function. We can provide the firmware EPROMs if you need them.

Can I use this board with the long-haul fiber boards?
The NFMC1F1E manages the routing and status of links, but it relies on the transceiver boards to handle the physical layer. If you’re using long-haul boards with different wavelengths, the master controller will still manage the routing—it’s transparent to the physical layer. The diagnostics will work as long as the transceiver boards provide the necessary status signals.

Can I hot-swap this board?
No. Mark IV backplanes are not hot-swappable. The 1F1E has 6 securing screws—make sure they’re all properly engaged before powering up.

What’s your warranty and lead time?
We stock the NFMC1F1E in limited quantities. Lead time is 2-3 business days. We offer a 2-year warranty. We test every board with a 48-hour burn-in, a thermal cycle (-55°C to +85°C), a vibration test on our shaker table, and a full diagnostic verification. The test report is included.

Is this board compatible with the Mark VIe?
No. This board is for Mark IV systems only. The backplane architecture is different.
