DS3800NFEE1C1B | New Surplus GE Turbine Control Board

Description

Product Introduction

The DS3800NFEE1C1B is the top-tier single-channel fiber optic board—combining extended range, enterprise-grade diagnostics, and environmental protection in one package. The suffix tells the story: the first “1” indicates a hardware revision. The “C” specifies 1300nm long-wave transceivers with a 5km range. The second “1” adds enterprise-grade diagnostic features (predictive failure alerting, historical error logging, detailed status reporting). The final “B” is the conformal coating. This board was designed for single-link installations where long range, proactive maintenance alerts, and environmental protection are all required.

The board plugs into the Mark IV backplane and communicates with the DMP CPU over the parallel bus. The 1300nm transceivers operate at 2Mbps and support fiber runs up to 5km on 62.5/125µm multimode fiber. The enterprise-grade diagnostics provide predictive failure alerting—giving you days or weeks of advance warning before a link fails. Compare this to the NFEC1B1B (same range, conformal coating, but expanded diagnostics without predictive alerting). The NFEE1C1B adds predictive capability for customers who need proactive maintenance.

Frequently Asked Questions (FAQ)

What’s the difference between the NFEE1C1B and the NFEC1B1B?
The NFEE1C1B adds predictive failure alerting and historical error logging. The NFEC1B1B has expanded diagnostics but lacks predictive capabilities. The NFEE continuously monitors optical power trends and can predict when a fiber link is likely to fail—allowing you to schedule maintenance before the link goes down. If you need proactive maintenance alerts, choose the NFEE. If you only need real-time diagnostics, the NFEC is sufficient.

What’s the “Predictive Alert” LED?
The Predictive Alert LED indicates that the board has detected a trend suggesting an imminent link failure. The board continuously monitors the received optical power and error rates. If the power drops by more than 3dB over a rolling 30-day period, or if the error rate exceeds a threshold, the LED turns red and the board logs a predictive alert. This gives you advance warning—typically days or weeks—to clean connectors, replace fiber, or schedule maintenance.

Do I need to upgrade my DMP firmware for the predictive alerting?
The predictive failure alerting requires DMP firmware v3.5 or later. If you’re running an older firmware version, the board will still work, but the predictive alerting won’t be available. We can provide the firmware EPROMs for the upgrade if needed.

Can I use this board with single-mode fiber?
The 1C1B is designed for multimode fiber (62.5/125µm) with ST connectors. The transceivers are LED-based and aren’t powerful enough to couple efficiently into single-mode fiber. Use multimode fiber for full performance.

What’s the most common failure mode on the NFEE1C1B?
We’ve serviced about a dozen of these boards. The most common failure is the 1300nm LED transceiver—it degrades over time, reducing optical power output. The predictive alert feature will typically warn you before the link fails completely. We replace the transceiver module. The edge connector is the second most common failure—corrosion from humidity. The board is repairable.

Can I hot-swap this board?
No. Mark IV backplanes are not hot-swappable. Power down, lock out, wait 60 seconds.

What’s your warranty and lead time?
We stock the NFEE1C1B in limited quantities. Lead time is 2-3 business days. We offer a 1-year warranty. We test every board with a 24-hour burn-in, a fiber optic loopback test (with a spool of 5km fiber), and a 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.
