Organize 12 singlemode fiber connections in a cassette format built around LC/APC optical interfaces. The LC/APC-12 provides a defined 12-port connection point for installations that require LC connectors with angled physical-contact polishing. It is suited to fiber distribution points where port count, fiber mode and connector type must match the installed optical infrastructure. Singlemode fiber supports long-reach optical links commonly used between telecommunications rooms, equipment areas, campuses and service-provider handoffs. LC/APC connections use an angled end-face geometry intended to reduce reflected optical signal at the connector interface. This makes connector compatibility important: the cassette should be selected for installations already standardized on singlemode LC/APC connectivity. The 12-port layout concentrates twelve optical interfaces in one cassette, helping maintain a consistent connection format across a fiber termination field. Specify this cassette when the required interface is LC/APC and the required density is 12 ports. Its combination of singlemode support, LC/APC connectivity and cassette construction distinguishes it from fiber components built for other connector styles, polishing methods, fiber types or port counts.
