Komshine EX39 Handheld Fiber Optic Fusion Splicer

The Komshine EX39 Handheld Fiber Optic Fusion Splicer is a compact and lightweight fusion splicing machine designed for FTTH, FTTx, aerial fiber installation, telecommunications, and fiber optic maintenance. It uses active clad alignment technology for accurate fiber positioning and provides fast 8-second splicing and 18-second heating. With a 3.5-inch high-resolution display, 320x magnification, replaceable universal fiber holder, automatic arc calibration, and a rechargeable battery, the EX39 is well suited for professional field and aerial fiber splicing.

Product Features

Active Clad Alignment

Provides accurate fiber alignment to achieve reliable and low-loss fusion splices across common fiber types.

Fast Splicing and Heating

The EX39 provides approximately 8-second splicing in quick mode and 18-second heating, helping improve field installation efficiency.

Compact Handheld Design

Its lightweight and portable construction makes the EX39 convenient for FTTH installations, maintenance work, and aerial fiber operations.

3.5-Inch High-Resolution Display

The 800 x 480 color display and 320x magnification provide clear fiber viewing during alignment and splicing.

Universal Replaceable Fiber Holder

The 3-in-1 replaceable fiber holder supports different fiber and cable configurations, including 0.25 to 3.0 mm fiber and indoor flat cable.

Automatic Arc Calibration

The splicer automatically calibrates arc power according to air pressure and temperature to help maintain consistent splice quality.

Long Electrode Life

The replaceable electrodes support up to 5,000 arc discharges, helping reduce maintenance frequency during regular use.
