         6 . The component tray of  claim 2 , wherein first and second flexible latches are positioned at the concave side of the tray body. 
     
     
         7 . The component tray of  claim 5 , wherein first and second flexible latches each include a flexible cantilever portion and a cam portion positioned at the concave side of the tray body. 
     
     
         8 . The component tray of  claim 7 , wherein the cantilever portion is substantially parallel to the central axis and the cam portion defines cam surfaces aligned along planes that are angled relative to the central axis. 
     
     
         9 . The component tray of  claim 8 , wherein the planes converge as the planes extend toward the concave side of the tray body. 
     
     
         10 . The component tray of  claim 1 , further comprising excess fiber storage locations positioned adjacent to ends of the tray for storing optical fiber in a looped/coiled configuration. 
     
     
         11 . The component tray of  claim 1 , wherein the component mounting location has a compact configuration adapted for securely attaching optical components to the tray body. 
     
     
         12 . The component tray of  claim 1 , wherein the component mounting location is adapted for mounting wavelength splitting components to the tray body. 
     
     
         13 . The component tray of  claim 1 , wherein the component mounting location is adapted for mounting splice sleeves to the tray body. 
     
     
         14 . The component tray of  claim 5 , further comprising retention structures at the component mounting location that define a plurality of elongated pockets having lengths aligned substantially perpendicular relative to the central axis. 
     
     
         15 . The component tray of  claim 14 , wherein the pockets of each location are arranged in a row of pockets with the lengths of the pockets being substantially parallel to one another. 
     
     
         16 . The component tray of  claim 15 , wherein each of the pockets is defined between two resilient retention members that are substantially parallel to one another and that extend at least a majority of the length of the pocket. 
     
     
         17 . The component tray of  claim 16 , wherein the two resilient retention members have cantilevered configurations with base ends integrally formed with the base of the tray. 
     
     
         18 . The component tray of  claim 17 , wherein the two resilient retention members have elastic characteristics when bent about the base ends in an orientation transverse to a length of the resilient retention members.
