Official TEKCN demonstration videos — splice speed tests, loss measurements, ribbon splicing and machine features in action.
TC-600: real splice speed test
Full-speed recording of the TC-600 six-motor trunk splicer completing a splice cycle — 6 s splice, 16 s heat.
Watch video →Splicing with red-light (VFL) demo
Visual demonstration of fiber splicing with red-light assistance showing fiber alignment inside the machine.
Watch video →Multi-function fiber holder demo
How the multi-function clamp holds drop cable, pigtail and bare fiber without changing fixtures.
Watch video →Splice speed field test
Timed field test of splice cycle speed for high-count trunk construction projects.
Watch video →Splice loss test
Measured splice loss values on standard SM fiber — typical results around 0.02 dB.
Watch video →AI free-alignment design
Introduction to the AI auto-alignment design that removes manual arc calibration from daily operation.
Watch video →Dual V-groove design demo
Demonstration of the dual V-groove fiber alignment structure and its effect on splice consistency.
Watch video →Swappable fiber holder demo
Swap fiber holders in seconds — one machine covers single fiber, ribbon and specialty fiber jobs.
Watch video →Ribbon fiber cleaving & splicing demo
End-to-end mass-fiber workflow: ribbon stripping, ribbon cleaving and mass splicing on the TC-600M.
Watch video →Ribbon splice loss test
Measured loss on mass-spliced fiber ribbons for backbone and high-density trunk construction.
Watch video →Press mechanism showcase
Close-up of the fiber cleaver press structure that ensures repeatable, low-angle cuts.
Watch video →TC-400 AI alignment algorithm demo
The TC-400 PAS splicer adjusting arc power automatically via its AI alignment algorithm.
Watch video →TC-400 FAST mode introduction
FAST mode trades a fraction of loss margin for speed — ideal for drop-cable FTTH work.
Watch video →Manual vs automatic mode comparison
Side-by-side timing of manual and fully-automatic splicing modes on the same machine.
Watch video →Splice speed comparison test
Splice cycle time compared between models to help choose the right machine per job.
Watch video →Red-light splicing demo (2nd angle)
Second demonstration angle showing red-light assisted fiber observation during splicing.
Watch video →Multi-function holder demo (2)
Another look at the multi-function holder handling different cable types.

Fiber cleavers: blade care and clean cuts
Most "splicer problems" in the field are actually cleaver problems. This lesson covers the care routine that keeps cleave angles u…
Start lesson · 12 min → Lesson 13Fiber cleavers: choosing the right model
Cleave quality caps your splice quality — the best six-motor splicer cannot fix a 2° cleave angle. This lesson maps cleaver classe…
Start lesson · 10 min → Lesson 12Drop-cable stripper pliers in practice
The three-port stripper is the everyday tool of FTTH. Each port has a different depth — using the wrong port is the number-one cau…

A cable opener scores the outer jacket without touching the loose tube underneath. Ten seconds of tool discipline saves meters of …
Start lesson · 8 min → Lesson 10Fiber & cable fusion splicing, end to end
The complete professional workflow from opening the cable to closing the closure, using a six-motor core-alignment splicer. Follow…
Start lesson · 22 min → Lesson 9Cold splicing (mechanical splicing) of optical cables
Mechanical splices align two cleaved fibers in an index-matched channel — no arc, no power. Done correctly they hold 0.1–0.15 dB f…
Start lesson · 11 min → Lesson 7Field termination methods for optical cables
Splicing, mechanical splicing and pre-terminated connectors each have a cost/speed/reliability profile. This lesson helps you pick…
Start lesson · 16 min → Lesson 5Fiber end-face inspection with inspection scopes
More than half of all optical link faults come from contaminated end faces, not from bad splices. This lesson teaches the inspect-…
Start lesson · 14 min → Lesson 3Patch cords: structure and selection
The patch cord is the most replaced — and most abused — component in an optical link. Choosing the right connector, polish type an…
Start lesson · 9 min → Lesson 2Optical cables: types and construction
Before you splice, terminate or repair anything, you must know what is inside the cable. This lesson walks through the common outd…
