Fiber Optic Adapter
SC-PC-K
01
The fiber optic adapter with a cap is a precision passive device that enables efficient docking of optical signals in fiber optic communication systems. With its unique dust - proof design and stable performance, it has become a preferred component for various fiber optic network deployments.
Its core function is to accurately align and connect two fiber jumpers or pigtails. Through the high - precision positioning of the internal ceramic ferrule, it ensures low - loss transmission of optical signals. The typical insertion loss can be controlled below 0.2dB, and the return loss is better than 50dB, meeting the stringent requirements of high - rate communication.

Compared with ordinary adapters, the dust cap design is its core highlight. It is made of aging - resistant engineering plastics or anti - oxidant metal materials, and closely fits with the adapter body through a snap - on or threaded structure. It can completely seal the interface when not in use, effectively blocking dust, water vapor, oil stains and other pollutants. This design can extend the cleaning cycle of the fiber end face by 3 - 5 times, significantly reducing the risk of signal attenuation or link interruption caused by pollution. It is especially suitable for dusty industrial environments, outdoor cabinets or scenarios with frequent plugging and unplugging.

The product covers mainstream interface types such as SC, LC, FC, and ST, supports the compatibility of single - mode and multi - mode fibers, and some models also have a duplex design, which can transmit bidirectional optical signals at the same time. The shell is made of high - strength ABS or zinc alloy, which is resistant to high temperature and impact. The operating temperature range is as wide as - 40℃ to 85℃, enabling it to adapt to complex climatic and environmental conditions.
In fields such as data center cabling, Fiber - To - The - Home (FTTH) projects, security monitoring systems, and telecommunications backbone networks, the fiber optic adapter with a cap provides key support for the long - term and reliable operation of optical communication networks by improving maintenance efficiency and link stability.
