Plug and Play Cassette, LC, MM 50 - Optical cassettes are adapter panels installed with factory terminated MTP multifiber fanouts. The cassettes can be snapped into most Hubbell fiber patch panels, enclosures or cabinets that accept FSP series adapter panels. These cassettes provide significant installation labor savings because connector termination is not required in the field. The fanouts are housed in a durable metal cassette and, are terminated, at the rear, to a 12-fiber MTP ribbon connector.
