Feature                          1. Based on the pluggable non-preset tube technology                          2. Precision ceramic components with co-axial self centering, Excellent and durable optical property                          3. Optical fiber fits axially in elastic way and avoids completely any false connect                          4. Triple clamping through the naked fiber, tight buffer and cable, etc., can be used as patchcord                          5. High on-line tensile strength of Optical Fast Connector after terminating, always keep connecting    under the force from cabling and drawing.                          6. Integrated protection of the casing to withstand harsh user environment.                          7. Directly connectable with ONU without any optical socket, which reduces FTTH cost.                          8. High success rate and easiness in installation with average splicing time 100 sec                          9. Lower requirement for the habit working and work environment call for to the builder.                          10. Visible Installation quality; independent from any far end light source and special device satisfying cabling construction in any sectioned way.                 Specification                                       ITEM            Technical Parameters                                Applicable for            3.1 x 2.0 mm Drop cable                                Optical fiber diameter            125μm ( 657A & 657B )                                Tight buffer diameter            250μm                                Fiber mode            Single mode                                Operation time            About 100s(no fiber cut)                                Insert loss            ≤ 0.3dB(1310nm & 1550nm)                                Return loss            ≥40dB                                Fastening strength of naked fiber            >5 N                                Fastening strength of naked fiber holder            >10 N                                Tensile strength            >50 N                                Using temperature            -40~+80°C                                On-line tensile strength (20 N)            IL ≤ 0.2dB  RL ≤ 5dB                                Mechanical durability (500 times)            IL ≤ 0.2dB  RL ≤ 5dB                                                         Drop-off test (drop-off height 4m,                                      once per direction, totally 3 times)                        IL ≤ 0.2dB  RL ≤ 5dB
