In global FTTH, FTTD, municipal fiber networks and data center microcable blowing deployment projects, reliable mechanical tensile performance of microduct connectors is the core guarantee for stable long-distance cable blowing, pipeline laying and long-term underground operation. IEC60794-1-2 Method E1, the international unified tensile strength test standard for optical cable and microduct accessory systems, has become a core compliance threshold for microduct connectors to enter mainstream telecom markets worldwide. As the authoritative mechanical testing clause under the IEC 60794 optical cable general specification, it strictly verifies the connection firmness, structural tensile resistance and anti-separation performance of microduct connectors, directly judging whether products can withstand construction traction, pipeline tension and long-term ground settlement load without disconnection, leakage or structural failure.

3.1 Fix two ends of the microduct fitting assembly onto the upper and lower chucks of the universal tensile tester, ensure clamping without crushing microduct pipe wall.
3.2 Start the tester at uniform extension speed, gradually increase tension up to specified maximum test load
3.3 Maintain full tensile load stably, record real-time displacement, pipe separation and connector deformation data throughout holding period.
3.4 Full test recording items: Maximum bearing tension value; connector displacement elongation; joint separation gap; cracking, fracture or slip of lock structure.
4.1 After load release, the tensile force value displayed by the tester shall exceed the standard value specified for the corresponding dimension.The test is deemed passed if the measured value exceeds the standard requirement; otherwise, the test fails.

IEC60794-1-2 Method E1 is the unified mechanical test method under the global IEC optical cable standard system, specially applicable to microduct fiber unit accessories including db mciroduct fittings. This tensile test simulates all real tension scenarios on site: traction force during high-speed microcable blowing, horizontal pipeline stretching, vertical shaft hanging load, ground settlement and soil extrusion tension in buried pipelines.
Qualified tensile performance certified by this standard effectively avoids core project faults: micro conduit connectors pull-off during cable blowing leading to project rework, pipeline joint separation causing water/mud intrusion into microducts, long-term tension damage cutting off fiber transmission channels. FCST’s fully compliant tensile-certified HDPE Tube Connectors protect fiber network integrity, reduce post-construction maintenance costs and guarantee long-term stable operation of municipal, data center and residential FTTH fiber infrastructure.
