LOT OF 700 COMMSCOPE 1392598 BOOT SC .900 GREEN ROHS SC CONNECTOR BOOT - 900ΜM - GREEN T268702

The 1392598 is a standard fiber optic connector accessory. It is a 900µm (0.9mm) SC Boot, and the Green color signifies its specific use for Singlemode APC (Angled Physical Contact) connectors. In fiber optics, color-coding is strict: Green boots and housings are reserved for APC connectors to prevent them from being accidentally plugged into UPC (Blue) ports, which would cause high signal loss and potential hardware damage.
