The pigtail is terminated on one end with SC/APC connector. SC connectors are currently the most popular optical coupling elements due to simple matching (push-pull coupling with a snap), rectangular cross-section allowing dense packing of the connectors on the panel, and plastic construction (of course outside the ferrule). The ferrule of SC/APC connector is polished at an angle of 8 degrees.

SC/APC 1m Fiber Optic Single Mode Pigtails are characterized by low attenuation and back reflection (reflectance). They use highest quality ferrules. Each pigtail passes individual quality control (inspection of surfaces and measurement of transmission parameters – insertion and return loss).

The single-mode fiber used in pigtails is G.657.A2, with reduced water peak. The fiber provides full compatibility with existing fiber-optic networks based on single-mode fibers, including high-quality splicing.

The G.657.A2 fiber is currently one of the most advanced and popular single-mode fibers, being in fact an improved version of the G.652.D fiber. The fiber can be formed into tight coils due to reduced attenuation in such conditions, whereas other parameters are even a little better (attenuation less than 0.35 dB/km at 1310 nm and less than 0.20 dB/km at 1550 nm). The special feature this fiber type is reduced attenuation of coils – at 1550 nm the attenuation of 10 turns with a radius of 15 mm is <0.03 dB, and of 1 turn with a radius of 7.5 mm is <0.5 dB.
