Fiber optic enclosure for retrofitting pedestals in the field

A method of installing an optical module into a telecommunications device, the method comprising:

• accessing an interior of a housing through an access opening;
• inserting a module through the access opening and into the interior of the housing, the module including a module frame having a bulkhead that divides the interior of the housing into first and second regions, the module including a plurality of fiber optic adapters mounted to the bulkhead, the fiber optic adapters including first ports accessible at the first region of the housing interior and second ports accessible at the second region of the housing interior, the module including a removable cover mountable to the module frame for restricting access to the first region, the module including a tray mounted to the module frame within the first region of the housing;
• mounting a wavelength division multiplexer in the first region of the housing interior;
• coupling a first output of the wavelength division multiplexer to an input side of a passive optical power splitter provided at a front side of the tray;
• and
• plugging connectorized outputs of the passive optical power splitter into the first ports of the fiber optic adapters.
