摘　　要：Compact transmitter and receiver optical sub-assemblies（TOSA and ROSA） are fabricated in our laboratory and have an aggregated capacity of 100 Gb/s. Specially, directly modulated laser（DML） drivers with two layers of electrical circuit boards are designed to inject RF signals and bias currents separately. For all the lanes, the3 dB bandwidth of the cascade of the TOSA and ROSA exceeds 9 GHz, which allows the 12.5 Gb/s operation.With the 12.5 Gb/s × 8-lane operation, clear eye diagrams for back-to-back and 30-km amplified transmission with a dispersion compensation fiber are achieved. Low cost and simple processing technology make it possible to realize commercial production.Compact transmitter and receiver optical sub-assemblies（TOSA and ROSA） are fabricated in our laboratory and have an aggregated capacity of 100 Gb/s.
