Adapter plate for fiber optic module

An adapter plate for use with a telecommunications module that is configured to be slidably mounted to and includes a flexible latch for interlocking with a first type of telecommunications chassis, the adapter plate comprising:

• a body configured to be mounted to the telecommunications module and interlocked with the telecommunications module using the flexible latch of the telecommunications module, wherein the body of the adapter plate defines a front end with an opening and a rear end, wherein the telecommunications module is configured to be inserted into the body through the opening at the front end, wherein the adapter plate is configured to be slidably mounted to and includes a second latch for interlocking with a second type of telecommunications chassis that is different than the first type of telecommunications chassis, wherein the flexible latch of the telecommunications module is not configured for interlocking with the second type of telecommunications chassis, wherein the adapter plate includes upper and lower flanges for slidable insertion into opposing mounting slots of the second type of telecommunications chassis, and wherein the second latch of the adapter plate is positioned at the front end of the body and is configured to be positioned at the same end and adjacent the flexible latch of the telecommunications module when the telecommunications module has been mounted to the adapter plate such that a user can access from the same location either the flexible latch for removal of only the telecommunications module or the second latch for removal of both the adapter plate and the telecommunications module from the second type of telecommunications chassis.
