FF-3217 Medidor de potencia XGSPON 10G PON 

As a key client managing large-scale overlay migrations from legacy GPON to XGSPON and 10G EPON networks, the FF-3217 has proved invaluable for live link validation. It allows non-intrusive, synchronous pass-through testing across five distinct wavelengths: 1270 nm and 1310 nm uplink signals, as well as 1490 nm, 1550 nm, and 1577 nm downlink channels. The high channel isolation of over 40 dB effectively eliminates optical crosstalk between coexisting legacy and 10G-PON streams. Furthermore, with a pass-through insertion loss below 1.5 dB and measurement uncertainty under 0.5 dB, our technicians carry out live audits without causing data packet drops or service degradation on active subscriber lines.

Standardizing installation quality among contractors requires clear, objective testing metrics. The FF-3217 simplifies this process through its customizable threshold settings, enabling immediate "Pass/Fail" optical fiber authentication directly on the 3.5-inch color LCD display. The InGaAs detector delivers a refined 0.01 dB power resolution and accurately captures TDMA burst-mode upstream pulses at 1270 nm and 1310 nm down to -35 dBm. On high-power video channels at 1550 nm, it accommodates inputs up to +25 dBm without detector saturation. It is an essential key-authentication tool that guarantees network longevity before handing over completed spans.

Equipping hundreds of outside plant engineers with separate meters, fault locators, and copper wiremap tools was cost-prohibitive. The FF-3217 solves this by integrating five critical field functions into a single 350 g handheld chassis: a 10G PON power meter, a 10 mW Visual Fault Locator, and complete RJ45 cable distance, sequence, and tracking modules. Technicians can verify optical power at the ONT, locate macrobends inside cabinets with the VFL, and validate copper LAN drops using a single instrument. The internal 3.7V 4000 mAh rechargeable lithium battery easily sustains full-day field dispatches, significantly reducing our fleet equipment maintenance overhead.
