Abstract
Abstract The invention provides a locking bail that when in the locked position prevents the removal of an optical link module from a host system and when in the unlocked position provides a handle that facilitates the removal of an optical link module. By providing a locking bail, the packing density of modules in a host may be increased. The bail provides a handle which is accessible from the front of the module when the module is unlocked. The locking bail typically engages inclined planes on latch arms that secure an optical link module to the host system.
