Pigtail SC/APC SM 900UM G.657A 2M Pigtail Extralink with SC/APC connector is made of single-mode G.657A fiber, which is dedicated to FTTx technology. This fiber is characterized by a reduced bending radius, without an increase in attenuation. This is a very important feature when building an FTTx network due to the large number of changes in the direction of the optical line and due to the small size of cabinets and distribution boxes. Pigtail is used mainly for terminating customer cables in customer sockets and in the final distribution element.
