As a connection or termination unit for a fiber optic network when installed in the network termination equipment (NTE). Pre-assembling the 4-SC/APC connectors provides greater convenience and flexibility during installation. Subsequent devices (optical converters, distributors) are simply connected using optical patch cables, and the fiber optic itself can be routed from the box's installation location to the connection point using various installation methods. Here, only 4 fiber optic connectors need to be spliced or assembled. Length of fiber optic cable 15m.
