Fiber optic solutions for migration between duplex and parallel multi-fiber solutions

Fiber optic equipment that supports 8-fiber MPO configurations that enable migration between duplex transmission and 8-fiber parallel transmission is disclosed. The fiber optic equipment comprises at least one front multi-fiber adapter at a front end of the panel assembly, each adapter having a front side and a rear side. The fiber optic equipment also comprises at least one pass-through channel configured to receive at least one optical multi-fiber cable therethrough, wherein the rear side of the at least one front multi-fiber adapter is configured to optically connect to a first multi-fiber optical cable extending from a rear end of the panel assembly toward the front end. The front side of the at least one front multi-fiber adapter is configured to optically connect to a second multi-fiber optical cable extending from the rear end of the panel assembly toward the front end of panel assembly and passing through the at least one pass through channel.
