FAQ

Q1. How do I choose between the three models? XHT-M05-E2800 is the lowest-cost, high-volume pocket unit; XHT-M05-S4200 adds the 4.3 in screen, one-key auto test, 1490/1577 PON power and the Bluetooth app with report printing; XHT-M05-P460 is the highest-integration platform that further adds end-face inspection, insertion-loss testing, smart diagnostics, voice results and PC-like file management.

Q2. Which wavelength should I select? Match the wavelength to the test and the PON generation; all models use G.652 single-mode fiber:
  •  1550 nm (single wavelength) — lowest-cost, lowest-attenuation and longest-reach, for break and length locating on access and last-mile fiber; live-rated builds tolerate residual power on the drop side.
  •  1310/1550 nm (unfiltered, D1) — standard dual-wavelength acceptance of dark fiber, access and LAN/WAN links; the live-rated D1-Live on P460 is for low-light checks on the drop/branch after the splitter.
  •  1610 nm — out-of-band live wavelength for legacy networks, largely superseded by 1625/1650.
  •  1625 nm (high-pass filtered) — in-service maintenance of GPON/EPON drop fibers after the splitter.
  •  1650 nm (band-pass filtered) — in-service maintenance of XGS-PON/10G PON drop fibers after the splitter, clear of the 1577 nm band.

Q3. Can these handheld OTDRs test through a PON splitter on a live PON? No. These pocket OTDRs (20–26 dB) test live only on the drop/branch fiber after the splitter; they cannot test through it. Testing through splitters (e.g. 1:64) on a live network requires the dedicated XHT-M06 PON OTDR, which combines higher dynamic range with out-of-band filtered wavelengths.

Q4. What is the difference between the no-event-map and standard versions? The no-event-map version shows the raw trace and is intended for technicians who only need the lowest-cost break location; the standard versions add the icon-based event map that labels connectors, splices, bends and the end point automatically.

Q5. What does the smartphone app provide? Over Bluetooth, the app offers remote control, data sharing and direct printing of test reports on XHT-M05-S4200 and XHT-M05-P460, so results can be delivered from the field without a separate PC.

Q6. MOQ, lead time and accessories? MOQ 1 for all models; reference lead time 5 days for E2800/S4200 and 7 days for P460. Connector interfaces (SC/UPC, SC/APC, FC, ST) and volume orders are arranged on request. Each unit ships with battery, charger, data cable, carrying case, cleaning wipes, calibration certificate and user guide.

Ordering

• Part number: XHT-M05-E2800-[1550 no-map / 1550 standard / 1610 standard] · XHT-M05-S4200-[F1/F2/F3/F4 live or D1] · XHT-M05-P460-[F1 / D1 / D1-Live].
• Orders are checked against the confirmed model, wavelength and live-fiber capability before packing; response within 24 h.

To recommend the correct OTDR: tell us the network (last-mile, access or PON), whether live testing is required and on which wavelength, whether a smartphone app and report printing are needed, and whether end-face inspection or 1490/1577 PON power is required.
