Medidor de potência FF-3216 10G PON

Integrating the FF-3216 into our XGS-PON rollout provided our field teams with exact multi-wavelength pass-through analysis. The internal optical filtering offers outstanding channel isolation exceeding 40 dB across all four primary PON bands—1270 nm, 1310 nm, 1490 nm, and 1577 nm. This prevents cross-talk interference when evaluating coexisting legacy GPON and 10G-PON signals on the same drop fiber. With an insertion loss of less than 1.5 dB, our technicians perform live, non-intrusive pass-through power checks at the ONT/ONU interface without degrading active subscriber data links. The InGaAs detector delivers stable, repeatable readings with measurement uncertainty under 0.5 dB, making it an essential diagnostic tool for high-density FTTH turns.

Measuring burst-mode upstream optical signals on TDMA-based PON architectures is notoriously difficult with standard power meters, but the FF-3216 handles 1270 nm and 1310 nm upstream bursts flawlessly across its -35 to +10 dBm range. On the downstream side, the high-power headroom on 1577 nm (measuring up to +25 dBm) prevents detector saturation near the OLT transmitter. The ability to store up to 10 custom pass/fail threshold sets on the device has significantly accelerated contractor site acceptance testing. Field crews get immediate visual feedback on the color LCD display with a clean 0.1 dB resolution, and test records offload via the USB data interface for streamlined compliance archiving.

Outfitting our regional turnkey installation crews with the FF-3216 has noticeably improved commissioning efficiency. Weighing just 240 grams with dimensions of 186 x 100 x 50 mm, the unit is light enough for all-day field use in aerial splice trays and cramped street cabinets. Running on three standard 1.5V AA batteries, it yields over 12 hours of active measurement time and more than 20 hours of standby time, eliminating the charging downtime associated with internal lithium packs during long shifts. Backed by universal SC/APC and SC/UPC connector options, it is a durable, highly cost-effective precision instrument for 10G optical network audits.
