Optical SC/UPC Single-mode 9/125um FAST connector with minimum instrumentation requirements for connector installation – the connector does not need to be polished. An optical fiber cleaver, stripping pliers and optical fiber cleaning solution are sufficient to install the connector – no special tools are required. The connector contains a pre-polished part of the fiber and the connection to the optical fiber takes place in a special gel. Another advantage is easy installation in the field and speed of assembly – one fiber is connected within 30 seconds, including preparation. Typical embedded attenuation is 0.2 dB.
