The Molex 1061563000 is an FC/FC simplex fiber optic coupler from the 106156 series, designed for singlemode fiber applications. It terminates both ends as FC receptacles, making it a bulkhead adapter for joining two FC-terminated patch cables or for panel-mount fiber distribution. The phosphor bronze ferrule provides corrosion resistance in telecom central-office and outdoor cabinet environments, while the polymer housing keeps weight low for rack-mount density. A dust cap is included to protect the ferrule bore when the port is unmated.
Mounting is panel-mount bulkhead — the coupler passes through a panel cutout and is retained by the threaded barrel and nut. The simplex configuration means one fiber channel per unit; for duplex links, two units are required. The FC receptacle interface uses the standard ferrule alignment sleeve, compatible with any FC/PC or FC/APC connector. The silver-colored body is typical for standard FC adapters; no keying or color-coding for APC angle is present.
