The optical drawer  VIGI OP  144 3L1  is a drawer  modular for 12  12 fiber strand cassettes  optics.
 
 The 12 cassettes are distributed over 3 sliding and independent trays.
 Each tray receives 4 cassettes that connect separately.   Accepted cassettes are MTP / LC conversion cassettes and / or splice cassettes.
 
 This drawer provides maximum density over a height of 1U at sites where  the density of optical connections is a critical issue in terms of saving space in racks, such as data centers.
 
 The LC connectors as well as the jumpers are mechanically protected from accidental impacts by the front door of the drawer, and the attached and secure jumper on the front of the trays, up to the openings provided on each side.  The stirring of each tray is therefore done laterally, in order to provide a stirring  by bundles.
 
 The cables are also stowed behind on each side, which saves depth.
