The ST-ST Multimode Duplex Fiber Optic Adapter is a reliable alignment component designed for connecting ST connectors in multimode fiber optic networks. It ensures precise core alignment and stable optical performance, making it suitable for structured cabling systems, LAN networks, and enterprise fiber infrastructure.

Built with a durable PBT (UL 94V-0) flame-retardant housing, this adapter offers excellent mechanical strength and long-term stability. Its precision alignment sleeve ensures low insertion loss and consistent signal transmission even under repeated mating cycles. The beige color housing follows industry-standard multimode identification practices, making it easy to distinguish within complex fiber systems. OEM/ODM customization is available for housing color, material, and connector configurations.
