Cleerline™ CTG-MTSC12-SMA-B1 is a 12-fiber, Single-mode OS2 HD MTP® Elite cassette with SC APC front ports, 1x12F MTP Male APC rear connector, and Type B1 polarity. Cleerline™ HD MTP® Elite Cassettes provide a fast, modular solution for managing high-density links. Each cassette integrates an internal MTP Elite low loss to LC or SC breakout, eliminating pigtails and separate splice trays. A rear MTP male (pinned) connector with adapter accepts female (unpinned) trunks or jumpers. Inside, guided fanout routing and strain-relief features maintain bend radius and organization. These cassettes are sized to fit any LGX-compatible opening. A removable transparent cover supports easy visual verification, and all units include port ID labeling, and dust caps.
