TEKCN TC-400i Core Alignment Fusion Splicer – Faster Heating, Bigger Screen, Built-in GPS
The TEKCN TC-400i is the upgraded evolution of the TC-400 platform, engineered for technicians who demand faster throughput and a better viewing experience in the field. Its standout upgrades are a blazing 9-second heating time (vs. 16 seconds on the TC-400), a larger 4.73-inch full HD capacitive touchscreen, and a built-in GPS tracking system via SIM card — all in the same compact 1.5kg body. When every second counts on a high-volume FTTx rollout, the TC-400i’s faster heat cycle translates directly into more splices per day.
Why Choose the TEKCN TC-400i?
- 9-Second Heating Time: Nearly 2x faster than the TC-400’s 16-second heat cycle — a major productivity advantage on large-scale projects with hundreds of splices per day
- 4.73-Inch Full HD Touchscreen: Larger display than the TC-400 (4.3") for clearer fiber inspection and easier operation, especially in bright outdoor conditions
- Built-in GPS (SIM Card): Integrated GPS positioning and tracking system via SIM card — always active, no optional add-on required
- Core-to-Core Alignment: True core alignment technology delivers consistent 0.02dB SM splice loss across all standard fiber types
- 760X Maximum Magnification: Supports X, Y, or simultaneous dual-axis view for precise fiber inspection and alignment verification
- 250+ Battery Cycles: Slightly more cycles per charge than the TC-400 (250 vs. 220) for longer field sessions
- Waterproof, Dustproof, Anti-Shock: Ruggedized construction for reliable performance in harsh outdoor environments
- Button + Touchscreen Dual Operation: Flexible control options for use with or without gloves
Ideal Applications
- High-volume FTTH / FTTx fiber deployment requiring fast heat cycles
- Telecom access network construction and maintenance
- Projects requiring built-in GPS equipment tracking
- Field teams preferring a larger display for fiber inspection
- Enterprise and campus fiber cabling projects

Frequently Asked Questions
Q: How much faster is the TC-400i’s heating time compared to the TC-400?
A: The TC-400i heats in just 9 seconds, compared to 16 seconds on the TC-400 — nearly twice as fast. On a project with 500 splices per day, this saves approximately 58 minutes of heating time alone, significantly increasing daily throughput.
Q: Is the GPS on the TC-400i always included or optional?
A: The TC-400i has a built-in GPS system via SIM card that is included as a standard feature, unlike the TC-400 where GPS is an optional add-on. This provides real-time positioning and tracking for equipment security on job sites.
Q: What is the difference between the TC-400i and TC-400?
A: The TC-400i offers faster 9-second heating (vs. 16 sec), a larger 4.73-inch display (vs. 4.3-inch), built-in GPS (vs. optional), and slightly more battery cycles (250 vs. 220). The TC-400 has a faster 6-second splice time (vs. 7 sec) and comes with a more complete accessory kit including a folding stool.
Q: Does the TC-400i support all standard fiber types?
A: Yes. The TC-400i supports SM (G.652/G.657), MM (G.651), DS (G.653), NZDSF (G.655), and BI (G.657) — covering all standard fiber types used in FTTx and telecom network deployments.
Q: What warranty does the TEKCN TC-400i come with?
A: The TC-400i comes with a 1-year manufacturer warranty. For support or bulk pricing, contact us at info@splicermarket.com.
