Abstract

With the drastic expansion of internet usage, the demand of 10Gb/s transmission optoelectronic devices for local-area-network (LAN) and storage-area-network (SAN) are increasing. The key issues of these applications are to improve cost, manufacturability and reliability of optoelectronic devices in high speed transmission. The authors have demonstrated extremely low cost, high manufacturability and thermal stability optical fron-end for 10Gb/s Ethernet applications in this paper. High performance and high sensitivity of 10Gb/s transmitter optical sub-assembly (TOSA) and receiver optical sub-assembly (ROSA) with TO-Can packages are discussed and demonstrated to overcome the critical points in high speed applications, respectively. Moreover, 10km interconnection of 10Gb/s optical front-end without isolated elements inside are also proved to be error free at 10.3125Gb/s. In order to improve the signal integrity and manufacturability of 10Gb/s OSA in small form factor transceiver modules assembly, the authors also integrate high speed flex board and OSA package to extend the signal path, and to minimize the effect of crosstalk in modules. Furthermore, the integration of flex board and OSA package more release the difficulties in conjuunction OSA and electrical sub-assembly (ESA) in module to fulfill the request of 10Gb/s transeivers' Multi-Source Agreement (MSA). The performance of temperature stabilized TOSA over wide case temperature range is also experimented. The optical eye diagram of 10Gb/s TOSA developed in this study showing excellent eye quality passing 10Gb/s Ethernet mask test between 0°C to 85°C.
