XGS-PON / PON Power Meter

Wavelength-selective meters for live PON power, simultaneous channels and pass-through.

3 models · entry / standard / professional · 2–5 channels · MOQ 1

Unlike a broadband meter (XHT-M01), a PON meter uses narrow spectral passbands to separate upstream and downstream channels, display all channels together on coexistence networks, and read power in pass-through without disrupting service. Standard and professional models read ONU upstream burst; the entry model reads downstream only and is expandable by plug-in modules.

Key Concepts

Wavelength selectivity. Wavelength-selective channels distinguish upstream and downstream signals on a live PON; a broadband power meter (XHT-M01) reports total power and cannot separate them.
Simultaneous measurement. All channels of a coexistence network are displayed at the same time rather than one at a time.
Pass-through (through-mode). The meter is connected in line between the OLT and ONU and reads power without taking the link out of service; the added loss is specified as pass-through insertion loss.
Upstream burst mode. ONUs transmit upstream in TDMA bursts; burst-mode support measures that burst power on 1270/1310 nm instead of only a continuous signal.
PASS/FAIL. Configurable thresholds with reference calibration provide an immediate accept/reject result for acceptance.

FAQ

Q1. PON meter vs. a standard broadband power meter? A broadband meter (XHT-M01) reports total power referenced to a calibrated wavelength and cannot separate live PON channels. A PON meter (XHT-M02) uses narrow passbands to read upstream and downstream together and supports pass-through.

Q2. Can the entry model measure upstream or add channels? XHT-M0201 reads 1490/1577 downstream only. Optional on-site modules add 1270/1310 upstream, 1550 or 1610; the base unit cannot measure upstream burst (confirm burst capability before ordering). For built-in upstream burst choose XHT-M0211 or XHT-M0221.

Q3. MOQ, lead time and customization? MOQ 1 pc for all three; reference lead time 7 days. XHT-M0221 offers Spanish-language firmware and a custom boot-up logo for orders of 10 units or more.

Ordering

• Part number: XHT-M0201 (entry, downstream) · XHT-M0211 (standard) · XHT-M0221 (professional).
• MOQ 1 pc; reference lead time 7 days. Plug-in modules, connectors, RJ45 cable tracing, firmware and logo customization arranged on request.
• Orders are checked against the confirmed model, channels and connector before packing.

To recommend the correct meter: tell us the network (GPON/EPON, XGS-PON, or with 1550 RF video), whether in-service pass-through and upstream burst are needed, and the connector (SC/UPC, SC/APC or FC).
