Research on 100 Gbit/s Hybrid-Integrated EML Transmitter Optical Sub-assembly
owing to the thriving business of internet applications
such as cloud computing and big data
communication traffic is growing rapidly.The fifth generation mobile communication technology will also further accelerate this trend.In order to satisfy the need of high capacity
high terminal density
lower power dissipation of data center interconnectivity and the need of metropolitan area network application
100 Gbit/s optical module has evolved from Centum Form-factor Pluggable(CFP)to CFP2 and further to Quad Small Form-factor Pluggable(QSFP).The reduction in size and power dissipation of the optical module is a greater challenge to transmitter optical sub-assembly.Therefore
adopting hybrid-integrated packaging technology is the future direction for Transmitter Optical Sub-Assembly(TOSA)packaging
which can not only reduce the size of TOSA
but its power dissipation and cost as well.In this article
we introduce a QSFP28 100 Gbit/s hybrid-integrated Electroabsorption Modulated Laser(EML)TOSA
including its core technology
and show four eye diagrams that are up to the standard of 100 GBASE-LR4.Finally
a brief prediction of the future development of TOSA is made.
