Optical fiber input/output tray with wavelength division multiplexing support for a co-packaged optical switch

A switch, comprising:

• a switching controller;
• a co-packaged optical module having an optical data signal input and a laser input, the co-packaged optical module coupled to the switching controller;
• a front panel having couplers for an external laser source and an external optical signaling device;
• and
• an optical input/output tray having a first set of adapters coupled to the optical data signal input and the laser input of the co-packaged optical module, a second set of adapters coupled to the front panel, and a wavelength division multiplexing (WDM) component converting a plurality of multi-wavelength signals from the first set of adapters to a single multiplexed signal coupled to the second set of adapters and the WDM component converting a single multiplexed signal from the second set of adapters to a plurality of multi-wavelength signals coupled to the first set of adapters.

An optical input/output tray for insertion in a switch assembly having a front panel and a co-packaged optics module with an optical data signal input and a laser input, the optical input/output tray comprising:

• a housing insertable in the switch assembly;
• a first set of adapters connectable to the optical data signal input and laser input of the co-packaged optics module;
• a second set of adapters connectable to the front panel;
• a wavelength division multiplexing (WDM) component converting a plurality of multi-wavelength signals from the first set of adapters to a single multiplexed signal, the single multiplexed signal coupled to the second set of adapters, and the WDM component converting a single multiplexed signal from the second set of adapters to a plurality of multi-wavelength signals coupled to the first set of adapters;
• a fiber management structure positioned in the housing, the fiber management structure communicating optical signals between the first set of adapters, the WDM component, and the second set of adapters;
• a WDM module attached to the housing at a proximal end to the front panel, the WDM module holding the WDM component coupled to the second set of adapters;
• and
• a third set of adapters coupled to the WDM component and coupled to the fiber management structure.
