Abstract: Technologies are described for a fiber optic equipment chassis. The chassis may have a bottom plate and a top plate positioned such that the plates form a front chassis access and a rear chassis access. The chassis may include five module guides each having module guide channels for insertion and removal of fiber optic modules. The modules have two guide rails and movable tabs arranged in tab pairs to the front and to the rear. A tab catch on each of the tabs is configured to engage with guide catches and disengage when either tab pair is compressed toward a centerline of the module. The geometry of the modules provide a smaller total width than a distance between adjacent module guides while either pair of tabs is compressed. The smaller width can support removal of the fiber optic module from both the front access and the rear access.
