High-rate

large data capacity transmission and processing are key issues in future optical fiber communications.10Gbit/s 850nm Vertical-Cavity Surface-Emitting Laser（VCSEL）-Transmission Optical Subassembly（TOSA）is a key highrate short-wavelength subassembly used in Ethernet and large data processing centers.This paper introduces the structure

chip characteristics

technical indexes and relevant standards for the practical subassembly

reports the high temperature accelerated life test conditions for and results of its chips

discusses the effects of variations in structure

technology and environmental temperature on its performances and points out its applications in the short-range Ethernet and large data processing centers.
