TEKCN TC-200-V Fiber Optic Identifier with Built-in VFL – 750–1700nm, SM/MM, 60-Hour Battery
The TEKCN TC-200-V is a professional handheld fiber optic identifier with a built-in Visual Fault Locator (VFL), designed for nondestructive live fiber identification in FTTH, telecom, and CATV networks. Using a sensitive InGaAs detector, it clamps onto any fiber — without breaking the connection — and instantly identifies the fiber, detects traffic direction, and locates faults, all in a single compact instrument.
With a broad 750nm–1700nm wavelength range, the TC-200-V works on both singlemode (SM) and multimode (MM) fibers up to 3mm in diameter. The built-in 650nm VFL at 10mW output adds fault location capability, making this a true 2-in-1 field tool. Powered by 2×AA batteries with over 60 hours of runtime, it’s built for all-day field use without charging infrastructure.

Why Choose the TEKCN TC-200-V?
- Nondestructive Live Fiber Identification: Clamps onto the fiber without disconnecting it — identify live fibers safely without interrupting service or traffic.
- Broad 750–1700nm Wavelength Range: Covers all standard telecom wavelengths (850nm, 1310nm, 1490nm, 1550nm, 1625nm) in a single instrument — no need to switch tools.
- Built-in 10mW VFL at 650nm: Locate fiber breaks, bends, and connector faults visually — two critical field functions in one compact body.
- InGaAs Detector for High Sensitivity: Detects signals as low as −35dBm at 1550nm, ensuring reliable identification even on long or high-loss fiber spans.
- Tone Detection (270Hz / 1kHz / 2kHz): Identifies fibers tagged by a light source or tone generator — compatible with standard OLTS tone outputs including EXFO, Fluke, and others.
- SM & MM Compatible: Works on both singlemode and multimode fibers up to 3mm — one tool for all fiber types on the job site.
- 60+ Hour Battery Life on AA Batteries: No charging required — standard AA batteries available anywhere, ideal for remote field sites and multi-day projects.
- Lightweight at 200g: 230×43×48mm compact form factor fits in a tool pouch or jacket pocket.
What Is a Fiber Optic Identifier and How Does It Work?
A fiber optic identifier is a nondestructive field instrument that detects optical signals in a live fiber without breaking the connection. It works by applying gentle macrobend coupling — bending the fiber slightly to allow a small amount of light to escape — which the InGaAs detector captures and analyzes. The TC-200-V can:
- Confirm whether a fiber is live or dark
- Detect the direction of traffic (upstream vs. downstream)
- Identify a specific fiber by its tone frequency (270Hz, 1kHz, or 2kHz) when used with a compatible light source
- Locate fiber faults and breaks using the built-in 650nm VFL
This makes the TC-200-V essential for fiber maintenance, network troubleshooting, and fiber identification in multi-fiber cables — without ever disconnecting a live circuit.
Ideal Applications
- FTTH / FTTx network installation and maintenance — identify and trace individual fibers in distribution cables
- Telecom OSP and in-building fiber maintenance — locate faults and identify live fibers without service interruption
- CATV HFC fiber plant troubleshooting — trace fibers and locate breaks in hybrid fiber-coax networks
- Data center and enterprise fiber management — identify and label fibers in high-density patch panels
- Fiber construction acceptance testing — verify fiber continuity and identify specific fibers before splicing
TC-200-V vs. Basic Fiber Identifiers: What Makes It Different?
Most entry-level fiber identifiers only detect CW (continuous wave) signals and lack fault location capability. The TEKCN TC-200-V adds a built-in 10mW VFL — eliminating the need to carry a separate visual fault locator. Its InGaAs detector with −35dBm sensitivity outperforms silicon-based detectors on long-haul and high-loss spans. The 750–1700nm range covers CWDM and DWDM wavelengths beyond the standard 1310/1550nm window, making it future-ready for modern network deployments.
Frequently Asked Questions
Q: What is the TEKCN TC-200-V?
A: The TEKCN TC-200-V is a handheld fiber optic identifier with a built-in Visual Fault Locator (VFL). It nondestructively identifies live fibers, detects traffic direction, and locates faults — all without disconnecting the fiber — across a 750nm–1700nm wavelength range on both SM and MM fibers.
