Housed in a durable green plastic casing, this adapter ensures high-performance connectivity and precise alignment for duplex fiber optic cables. It is specifically designed to fit into standard SC-Simplex cut-outs, making it a versatile solution for various networking environments.
Advantages
This adapter offers exceptional mechanical stability and signal integrity, which are critical for maintaining high-speed data transmission. The inclusion of an integrated internal laser shutter provides an essential layer of safety by preventing accidental exposure to laser light when the connector is unplugged. Its compact design and standardized form factor allow for easy installation into existing patch panels and network equipment, while the secure clip-based fastening mechanism ensures that the connection remains stable even in high-density environments.
Suitable for
Telecommunications network infrastructure
Data center fiber optic patch panels
Enterprise-level local area networks
Single-mode fiber optic cabling systems
This adapter is not suitable for multi-mode fiber optic applications, as it is specifically optimized for single-mode signal transmission. Additionally, it should not be used in environments where the physical dimensions of the SC-Simplex cut-out are not available or where the connector type does not match the LC/APC standard.

To use the adapter, simply insert it into a compatible SC-Simplex cut-out on your patch panel or wall outlet until the clips snap securely into place. Once the adapter is mounted, align your LC/APC duplex fiber optic connectors with the ports and push them in until you hear a click. The internal laser shutter will automatically open upon insertion of the connector, allowing for seamless signal transmission.
What to consider before purchase
