3. Working temperature: -5℃~40℃, relative humidity: ≤85% (at 30℃), atmospheric pressure: 70~106Kpa;
4. Nominal working wavelength: 850nm, 1310nm, 1550nm;
5. Insertion loss: ≤0.5dB;
, Return loss: PC≥40dB, UPC≥50dB, APC≥60dB;
7: Dielectric strength: ≥3KV(DC)/1min, no breakdown, no arcing;
8. Insulation resistance: ≥1000MΩ/500V(DC);
9. Life: ≥1000 times.
