EndRun Technologies AFL3430 fiber optic transmitter 3430-0001-000

Product Description

EndRun Technologies AFL3430 Fiber Optic Link Transmitter – Model 3430-0001-000, 300-2500 MHz RF-over-Fiber

This used EndRun Technologies AFL3430 Fiber Optic Transmitter (Model #: 3430-0001-000) is a high-performance broadband optical link component designed to convert RF signals to light for transmission over singlemode fiber. It is the transmitter unit for EndRun’s AFL3430 system, which provides a secure, low-loss means of connecting GPS antennas and other RF sources to remote equipment .

The AFL3430 was originally introduced in 2006 as a premium solution for applications requiring extended antenna cable runs, enhanced lightning protection, or Tempest (RED/BLACK) isolation for government and military installations . The system was designed to support broadband transmission from 50-2500 MHz with exceptional link gain and noise figure .

Features & Benefits

• High-Performance Broadband Link: Designed with wide dynamic range for demanding RF applications

• Optically Stabilized Laser: Incorporates optical power feedback to actively adjust the laser for optimal linearity and constant power output over temperature and lifetime

• Integrated Bias-T: Provides current-limited +5VDC power via the RF input center conductor to power upstream active antennas or inline preamplifiers

• Extended Range: Supports fiber cable runs up to 5km (3 miles) without signal degradation

• Military/Grade Applications: Ideal for Tempest (RED/BLACK) isolation required by US Government and Military

• Versatile Configuration Options: The AFL3430 system can be configured with weatherproof outdoor transmitter or 1U rackmount indoor transmitter; can also operate with one transmitter powering two receivers

Original System Context

The AFL3430 system was originally introduced at a competitive price of $5,500 for the complete link (transmitter, fiber cable, and receiver) . This transmitter (Model 3430-0001-000) represents one component of that system. According to EndRun’s press releases, the system was designed to prevent damage to equipment racks from lightning strikes while providing virtually unlimited range between antenna and receiver .

The product has since been discontinued, with related components showing discontinuation dates in mid-2023 and 2024 . This makes this transmitter a valuable spare or replacement part for existing installations.
