Compact Receiver Module with Integrated Optical De-multiplexer for 40 Gbit/s and 100 Gbit/s

摘要

The authors have successfully developed new compact optical receiver modules with integrated optical De-multiplexer for 40GBASE-ER4 QSFP+ and 100GBASE-LR4 CFP4. These compact optical receiver modules achieved excellent wavelength specification and sensitivity. By applying the basic structure of the compact optical receiver module for 40GBASE-LR4 QSFP+, the newly developed modules are in the same form as the predecessor. The development of compact optical receiver modules are essential for QSFP+ and CFP4, which are compact optical transceivers, to realize 40 Gbit/s and 100 Gbit/s transmission, respectively. This paper describes the design and representative specification of the new modules.
