Ribbon Fiber Splicing Step by Step: Complete Mass Fusion Workflow with COMWAY C10R
Quick answer: A ribbon (mass fusion) splice follows six steps: ribbonize (if starting from loose fibers), thermal strip, clean, cleave, splice and protect. With a ribbon splicer like the COMWAY C10R, all fibers in the ribbon are fused in one arc, dramatically speeding up high-count cable work in data centers, backbone and FTTH feeder networks.
Why Ribbon Splicing?
Splicing fibers one by one in a 144- or 288-fiber cable takes hours. Mass fusion splices a full ribbon at once, cutting total splice time and closure preparation. It requires dedicated tools: a ribbon splicer, ribbon holders, a thermal stripper and a ribbon cleaver.
Tools You Need
| Step | Tool |
|---|---|
| Ribbonize loose fibers | FSM-100 ribbonizing tool (12 or 16 core) |
| Strip coating | COMWAY CS-09 thermal stripper (2 to 12 core) |
| Cleave and splice | COMWAY C10R kit (includes C109M cleaver) |
| Maintenance | V-groove cleaner, CE-04 electrodes |
Step 1: Ribbonize (If Needed)
When splicing loose-tube or single fibers to ribbon, arrange them in standard color-code order with the FSM-100 so they can be mass fused.
Step 2: Thermal Strip
Load the ribbon in its holder, let the heater warm up and strip in one smooth pass. See our thermal stripper comparison.
Step 3: Clean
Wipe the bare fibers with alcohol and lint-free wipes. Avoid fanning out or crossing fibers.
Step 4: Cleave
Cleave the full ribbon with the included high-precision C109M cleaver while fibers are still in the holder, then transfer directly to the splicer.
Step 5: Splice
Place both holders in the C10R, close the windshield and start. Check each fiber's estimated loss on screen and re-do the ribbon if any fiber fails. Compare ribbon splicers in our 16-core ribbon splicer guide.
Step 6: Protect and Maintain
Heat-shrink the ribbon splice protector and place it in the tray. Clean V-grooves regularly (see our V-groove cleaning guide) and replace electrodes when needed (see electrode replacement guide).
FAQ
How many fibers can be spliced at once?
Ribbon splicers typically handle 2 to 12 fibers, and newer models such as the COMWAY C10R 16-core version handle up to 16.
Can I mass splice loose fibers?
Yes, after ribbonizing them in color-code order with a tool like the FSM-100.
What is acceptable ribbon splice loss?
Average loss is usually slightly higher than single-fiber core alignment splicing. Always check your project specification.
Do I need a special cleaver for ribbon fiber?
Yes. Use a ribbon-capable cleaver, such as the C109M included with the C10R kit.
