MTP brand cassettes come in a variety of connector styles and modes, and can be your solution for saving space, time, and energy. The cassette itself is comprised of four parts:
MTP brand adaptor(s) in back
MTP brand connectors to SC/LC fan out assembly inside the cassette
SC, ST, MTRJ (including keyed MTRJ), and LC (including keyed LCs) adaptors in the front
The cassette module body can be configured to multiple manufacturers for and fit factor.
By plugging an MTP brand cable into the back, you're lighting up 12 or 24 (with quad LC) connections. For the 24-fiber application, you can have either one 24-fiber MTP brand cable or two 12-fiber MTP brand cables (plugging into two ports).
