Adapter panel with lateral sliding adapter arrays

An adapter panel arrangement comprising:

• a chassis body extending between opposite front and rear ends that are spaced apart from one another along a forward-rearward axis, the chassis body also extending along a width between opposite first and second sidewalls, the front of the chassis body defining an opening providing access to an interior of the chassis body from the front of the chassis body;
• a sliding member mounted to the chassis body to slide along the forward-rearward axis between a first position disposed within the interior of the chassis body and a second position disposed at least partially outside of the chassis body;
• and
• a plurality of optical adapters carried by the sliding member when the sliding member slides between the first and second positions, the optical adapters being located within the interior of the chassis during operative use of the adapter panel arrangement, the optical adapters being accessible from the front and the rear of the chassis body, the optical adapters defining groups of front adapter ports, each group being separately removable from the sliding member.
