They could be used together while the FHX cassette should match for FHX enclosure and the FHD cassette should match for FHD enclosure. They're only different in package style, but the cables sequence and interface of the model are the same. Usually, the FHX series products can be configured in the central apparatus room, and the FHD series products can be configured in the branch room. By FS on 17/05/2018

There is a label beside MTP adapter on rear and the package of every cassette, marking what polarity the casssette belongs to. By FS on 23/12/2017

Our MTP-12 cassettes are configured in accordance with the TIA Connectivity. Type A and AF should be used a pair in a two cassette method A link, using type A MTP-12 backbone cable to connect; B1 and B2 should be used a pair in a two cassette method B link, with type B MTP-12 backbone cable to connect. However, there is a limitation of method B that it doesn’t allow use of an angled polished (APC) single-mode connector. By FS on 16/08/2017

Male default. MTP male connector can be connected with MTP female cable. However, if you had MTP male cable and want one cassette with built-in MTP female connector to link, we can also do it. By FS on 10/07/2017

Hello, the difference between Type A and Type AF cassette is the polarity. Usually, Type A and Type AF are used as a pair in a two cassette method A link, and using Type A MTP-12 trunk cable to contact each other. We called it as A-A-AF. Also, if you use Type A cassette in both ends, it's available to use Type B trunk cable to contact them. We called it as A-B-A. Thanks! By FS on 12/09/2018
