It can be connected to the optical fiber by (plugging).

An optical adapter can have multiple ports (4 ports, 8 ports, 12 ports, etc.) to allow multiple or more out-of-doors to be connected, and some of these ports may be used for reasons such as accepting new subscribers or canceling existing subscribers. It can be left unconnected and the number of ports left unconnected is variable.

On the other hand, even if an unused port is left unsealed, optical adapters such as terminators may be damaged due to poor connection of individual subscribers or failure of local networks due to backlighting, rainwater flooding or contamination of foreign matter (yellow dust, dust, insects). It is common to insert individual caps into unused ports.

However, these individually inserted caps are often lost or damaged during the out-of-air construction at the sue for new subscribers or subscribers, so unused ports are left unopened.

In addition, the RN is installed at the height of the telephone pole or the outer wall of the building, and the optical adapter is stored inside the closed RN enclosure, so information on the presence or the number of unconnected ports of the optical adapter is not easily understood from the ground.
