<p>The present invention provides a host board system (2) in which transceivers (60-1) of two sizes (the larger approximately twice the width of the smaller) can be arbitrarily mixed within a given host board design. This is accomplished by specifying an arrangement of electrical connectors (90), a guide rail design (110) , a set of transceiver features, and a bezel (20) configuration to meet this need as well as the other requirements of optoelectronic transceivers. Typically, two slots (80) and connectors (90) are lined up behind an opening (30) in a bezel (20) that provides transceiver access (70) to two connectors (90). So that either double-width or single-width transceivers (60, 70) can be used in the same opening (30), the double-width transceiver (60) is designed to engage with the connectors (90) in the same position as a single-width transceiver (70). Further, the slots (80) and connectors (90) are spaced evenly so that all of the slots (80) and connectors (90) can accommodate a single-width transceiver (70) and all adjacent slots (80) and connectors (90) can accommodate a double-width transceiver (60).</p> |
