Abstract
An easily removable modular optical signal transceiver unit for conversion between modulated light signal transmission and electronic data signals and which conforms to the Small Form Factor standard for transceiver interfaces is disclosed. The structural details of its chassis include aspects which insure the proper positioning of electronic circuit boards of a transmitter optical subassembly and a receiver optical subassembly as well as the positioning of electromagnetic radiation shielding on the chassis. In conjunction with an interface device on an electronic circuit board of a host device, the chassis supports electromagnetic radiation shielding which substantially encloses the sources of electromagnetic radiation within the module and suppresses the escape of electromagnetic radiation, thereby preventing electromagnetic interference with sensitive components and devices in proximity to the module. During assembly, the chassis side walls are deflected, so that electronic or electro-optic components can pass over latching surfaces into contact with positioning surfaces for retaining the components in their assembled positions.
