説明

Light Travels at 299,792,458 Meters Per Second. Finding Where It Stopped Requires a Different Kind of Precision.

A fiber break at kilometer 73 on a live GPON trunk does not announce itself. There is no blinking LED, no error message on the OLT. What there is — is a neighborhood of angry customers and an ISP field technician driving toward a needle in a 100-kilometer haystack. The 100KM Pro Mini OTDR transforms that blind search into a measured, deterministic operation. This handheld optical time-domain reflectometer sends calibrated laser pulses down the fiber and reads the backscatter signature with sub-meter resolution — locating breaks, splices, connectors, and macro-bends within seconds of connecting to the line.

Designed for field use in FTTH/PON deployments, the 100KM Pro weighs under 1kg yet delivers a 100km measurement range with 32dB dynamic range — territory that once required a bench-top instrument at five times the size and cost. Its live-fiber testing mode works on active GPON/EPON networks without disrupting customer traffic, using a filtered 1625nm or 1650nm wavelength that rides above the 1490nm/1550nm data channels. The integrated VFL (Visual Fault Locator) provides instant visual break identification for patch panels and connector trays. Every trace auto-saves to the 8GB internal memory, with USB and Wi-Fi export for report generation back at the office.


Key Features

  • ✦ 100km maximum measurement range with 32dB dynamic range at 1550nm
  • ✦ Live-fiber PON testing at 1625nm/1650nm — no service interruption on active GPON/EPON networks

Application Scenarios

ISP field technicians use the 100KM Pro as their primary fiber qualification tool during FTTH rollout — certify each distribution segment before splicing the drop cable, and generate a trace report that becomes part of the customer installation record. Telecom maintenance crews carry it on preventive inspection rounds, running annual OTDR traces on long-haul backbone fibers to detect degradation before it becomes a customer-affecting outage. Data center engineers use it during greenfield builds to verify every trunk cable before patching — the auto-OTDR mode reduces verification time from 15 minutes per link to under 60 seconds. Military and utility network operators value its live-fiber testing capability, which lets them monitor fiber health on active circuits that cannot be taken offline for scheduled maintenance windows.

Frequently Asked Questions

Q: Can this OTDR test through a live GPON splitter?

A: Yes, with the 1625nm or 1650nm filtered port option, the OTDR can test through up to a 1:64 split ratio on a live GPON network. The filtered wavelength bypasses the ONT receiver filters without disrupting downstream traffic.

Q: What is included in the standard kit?

A: The standard kit includes the OTDR main unit, FC/UPC adapter, SC and LC interchangeable adapters, AC charger, USB cable, stylus, carry case, and user manual. A launch fiber box is recommended but sold separately.

Q: Is the 100km range realistic in the field?

A: The 100km specification assumes 1550nm wavelength on G.652 single-mode fiber at 0.20 dB/km attenuation. In practice, your range depends on total link loss from splices, connectors, and splitter insertion loss. A typical PON link with one 1:32 splitter will see 60-80km effective range.

Q: Can I export traces to third-party software?

A: Yes, the OTDR exports SOR (Bellcore GR-196) format trace files via USB or Wi-Fi. These files are compatible with industry-standard OTDR analysis tools including EXFO FastReporter and VeEX V-Sam.

Q: Does it support multimode fiber?

A: No, this OTDR is designed for single-mode (SM) fiber at 1310/1550nm. For multimode fiber testing at 850/1300nm, a separate MM OTDR module or instrument is required.

Q: How long does the battery last in the field?

A: The 4400mAh battery provides approximately 8 hours of continuous testing at 25 degrees C. In cold-weather field conditions below freezing, expect 5-6 hours. A full charge from empty takes roughly 3 hours via the included USB-C charger.

Q: Can this OTDR tell a bad mechanical splice from a good fusion splice?

A: Yes. The high-resolution event detection with 3m dead zone distinguishes between a fusion splice (typically under 0.1dB loss, appearing as a minor trace step) and a mechanical splice or dirty connector (0.5-1.5dB loss with a reflective peak). The auto-event table labels each event by type for field prioritization.

Perfect for data center fiber verification during greenfield builds

We use this OTDR to verify every trunk cable during data center commissioning — typically 30-80m SMF runs between racks. The sub-meter resolution catches bad LC connectors that a simple light-source/power-meter test would miss. Saved us from patching a $280 transceiver into a cable with a 4dB connector loss that would have caused intermittent link flaps. Build quality feels solid, the carry case is well padded. Battery lasts a full commissioning day without needing a charge.

Good field OTDR, auto-mode saves training time for new techs

Bought two units for our fiber maintenance team. The auto-OTDR mode is a godsend for junior techs — they press one button and the tool does the rest. Exporting SOR traces via Wi-Fi to our laptop works reliably. The VFL is bright enough to find breaks at the patch panel but not as powerful as a dedicated 30mW pen laser. The touchscreen can be finicky with gloved hands in the cold — a physical button for 'Start Test' would be nice. Overall very solid for the price, we will buy more.

This little OTDR punches way above its weight class

I do FTTH drop installations for a regional ISP and we used to rely on an EXFO unit that cost $4,000 and weighed 3kg. This 100KM Pro gives us the same 100km range in a package that fits in my tool belt pouch. The live-fiber PON testing at 1625nm is the killer feature — I can certify a GPON splitter segment without taking the line down. Tested it against our EXFO on the same fiber span at 42km and the trace overlay was within 1.5m. Impressive for the price.
