DS3800NFEE1E1E | New Surplus GE Turbine Control Board

Description

Product Introduction

The DS3800NFEE1E1E represents the pinnacle of single-channel Mark IV fiber optic boards—a board that combines enterprise-grade diagnostics with ultra-long-haul reach and aerospace-grade ruggedization. The suffix tells the story: the first “1” indicates a hardware revision. The “E” specifies a 1550nm laser-based transceiver with coherent detection—providing a 28dB optical budget, enough for 12km on single-mode fiber. The second “1” adds enterprise-grade diagnostic features (predictive failure alerting, historical error logging, detailed status reporting). The final “E” is the aerospace-grade environmental package: triple-layer conformal coating with ceramic-reinforced topcoat, radiation-hardened electronics, and MIL-STD-810G certification.

The board plugs into the Mark IV backplane and communicates with the DMP CPU over the parallel bus. The 1550nm laser transceiver operates at 2Mbps on single-mode fiber. Compare this to the NFEE1C1B (5km range, 1300nm LED, multimode fiber). The 1E1E gives you more than double the reach, with the highest level of diagnostics and environmental protection.

Frequently Asked Questions (FAQ)

What’s the difference between the 1E1E and the 1C1B?
The 1E1E uses a 1550nm laser and coherent receiver designed for single-mode fiber—12km range, 28dB budget. The 1C1B uses a 1300nm LED and PIN receiver designed for multimode fiber—5km range, 18dB budget. They are not interchangeable. Choose based on your installed fiber type and distance.

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 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. This gives you advance warning—days or weeks—to clean connectors or replace fiber.

What’s the temperature-compensated power tracking feature?
As the board temperature changes, the laser output power and receiver sensitivity change. The 1E1E has a temperature sensor and a microcontroller that adjusts the laser bias and receiver gain to maintain constant performance across the -55°C to +85°C range. The Temperature Compensated LED indicates that the compensation is active.

Is the laser safe to work with?
The 1E1E uses a Class 1 laser per IEC 60825-1. It’s eye-safe under normal operating conditions, but standard precautions apply—never look directly into the fiber connector with the board powered on.

Can I use this board with a standard NFCF at the other end?
No. The 1E1E uses a 1550nm laser and coherent detection. The standard NFCF uses 850nm LED. They won’t communicate. Both ends need to be 1E1E (or 1E, 1E1, 1J1E, etc.) boards.

What’s your warranty and lead time?
We stock the NFEE1E1E 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 fiber optic loopback test (with a spool of 12km single-mode fiber), 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.
