Our MTP fiber optic cassettes are designed to provide a secure and easy transition between multi-fiber cables to fiber optic patch cables. They come in both single mode OS2 (9/125 um) and multimode OM3 (50/125 um) and they also come in both 12 fibers and 24 fibers. Inside our 12 fiber cassettes, there is a 0.35-meter fanout cable from one male MTP adapter on the rear of the cassette connected to 6 duplex LC, SC, or ST adapters on the front of the cassette. Similarly, inside our 24 fiber cassettes, there are two 0.35-meter fanout cables from two male MTP adapters on the rear of the cassette connected to 6 quad LC adapters on the front. Both of these cassettes have a LGX footprint. The LGX size is 5.3'' by 1.2".
