Abstract: Disclosed is a latching apparatus for a pluggable optical transceiver module, which is configured to enable the pluggable optical transceiver module to be plugged or unplugged by pulling the pluggable optical transceiver module. The latching apparatus of the pluggable optical transceiver module connected to an optical connector and electrically connected to a cage assembly includes: a module housing, which is extended in a length direction and used to latch and fix the pluggable optical transceiver module to the cage assembly; and a clip-type latch, which is assembled through the outer circumference of the module housing and used to release the module housing from the cage assembly by horizontally and vertically moving with respect to the length direction in response to pulling of the clip-type latch when the module housing is unplugged from the cage assembly.
