Pigtail SC/APC SM 900UM G.657A 3 m long. This Extralink pigtail with a SC/APC connector is made on a  single-mode G.657A fiber, which is dedicated for FTTx technology. This fiber is characterized by its  reduced bending radius, without increasing attenuation. This is a very important feature during the construction of FTTx networks due to the large number of changes of optical line direction and because of the small size of cabinets and distribution boxes. Pigtails are used mainly in client cable terminations in the customer's sockets and in fiber optic distribution boxes.
