DS3800NFCF1F1E | Replacement for DS3800NFCF

Description

Product Introduction

The DS3800NFCF1F1E is the single-channel version of the NFCD1K1E—the board that combines 16km range with aerospace-grade environmental protection. The suffix tells the story: the first “1” indicates a hardware revision. The “F” specifies a 1550nm DWDM laser with an APD receiver and a 35dB optical budget—enough for 16km on single-mode fiber. The second “1” adds the diagnostic suite. 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 with 15g RMS vibration tolerance. This board was designed for single-link installations where 16km range isn’t enough—or where the environment demands aerospace-grade reliability.

The board plugs into the Mark IV backplane and communicates with the DMP CPU over the parallel bus. The DWDM laser operates at 1550.12nm (ITU channel 31) with an APD receiver that provides a 35dB optical budget. Compare this to the NFCF1F1D (same 16km range, DWDM laser, and APD receiver, but the “D” variant has military-grade components and 8g RMS vibration tolerance). The 1F1E adds aerospace-grade vibration tolerance (15g RMS), radiation hardening, and a ceramic-reinforced coating. This is the board for customers who need the range and the highest possible reliability in extreme environments.

Frequently Asked Questions (FAQ)

What’s the difference between the 1F1E and the 1F1D?
The “E” suffix adds aerospace-grade components, radiation hardening, and higher vibration tolerance (15g RMS versus 8g RMS). The 1F1D is military-grade; the 1F1E is aerospace-grade. The 1F1E also includes a ceramic-reinforced topcoat for abrasion resistance—the 1F1D does not.

Do I need to upgrade my DMP firmware for this board?
The wavelength locker and radiation event logging require DMP firmware v4.5 or later. If you’re running an older firmware version, the board will still work, but these features won’t be available. We can provide the firmware EPROMs for the upgrade.

Can I use this board with a standard NFCF at the other end?
No. The 1F1E uses a 1550nm DWDM laser and APD receiver. The standard NFCF uses 850nm LED. They won’t communicate. Both ends need to be 1F1E (or 1F1D, 1F, 1K1E, etc.).

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.

What’s the most common failure mode on the NFCF1F1E?
We’ve never had a 1F1E fail in the field. The aerospace-grade components make this board exceptionally robust. The only potential issue is the DWDM laser—the Laser Bias LED gives you advance warning of degradation.

Is the laser safe to work with?
The 1F1E uses a Class 1 laser per IEC 60825-1. It’s eye-safe under normal operating conditions.

What’s your warranty and lead time?
We stock the NFCF1F1E 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 16km 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.
