The present invention provides an optical transceiver with an optical subassembly optically coupling with an optical connector via a receptacle member, in which the optical subassembly is positioned to the housing of the transceiver without causing any mechanical stress. A vertical floodgate is installed on a partitioning wall and is driven in a vertical direction to be opened downwardly from a top toward a bottom. The method includes providing a host-site accessible to an on-line viewer and web-linkable to a retailer having an apparel site. The handle protrudes in a direction essentially perpendicular to the door panels and is connected to a latch mechanism for positively engaging with a corresponding latch mechanism in the door frame when the door is in a closed position. The first hollow bore passes through the past and terminates at an end of the post. The use of labels is not required and the methods can be performed in a high-throughput manner.
