Last updated: April 2026 dataSpecialized test and measurement equipment designed for telecommunications applications — including cross-talk meters, gain measuring instruments, distortion factor meters, and return-loss bridges — serves network operators, equipment manufacturers, and regulatory compliance labs. These instruments are essential for verifying signal integrity, channel performance, and interference levels across wireline, fiber-optic, and wireless infrastructure. As telecom networks migrate to 5G and high-capacity fiber, demand for precision RF and optical measurement tools in this category has grown, with sourcing concentrated among technically advanced manufacturing countries.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
SITC 87477 is reserved for instruments expressly designed for telecommunications use — such as cross-talk meters, distortion factor meters, and gain measuring instruments used in signal-path analysis. General-purpose electrical meters that happen to be used in a telecom setting but are not purpose-designed for it would typically fall under 87475 or 87478.
Instruments that themselves emit radio frequency energy as part of their measurement function may require FCC equipment authorization before importation and sale in the US. Passive measurement instruments that only receive or analyze signals generally do not require FCC authorization, but importers should confirm the specific instrument's RF emission profile with the manufacturer.
