Hiroshi Hara Atsushi Yasaki 40 Gbit/s QSFP+ 100 Gbit/s . CFP4 2012 . QSFP+ 40 GBASE-LR4 . QSFP+ 40 GBASE-ER4 CFP4 . 100 GBASE-LR4 .. With the rapid increase of data traffic in recent years, the development of compact optical receiver modules are essential to realize QSFP+, a compact optical transceiver for 40 Gbit/s and CFP4 for 100 Gbit/s. We developed a compact receiver module with an integrated optical De-multiplexer for 40 GBASE-LR4 QSFP+ in 2012. In order to enhance our product lineup, we have successfully developed new compact receiver modules for 40 GBASE-ER4 QSFP+ and 100 GBASE-LR4. CFP4. By applying the basic structure of the receiver module for 40 GBASE-LR4 QSFP+, the newly developed modules are in the same form as the predecessor.

2 These compact receiver modules achieved excellent wavelength specification and sensitivity. This paper describes the design and representative specification of new modules. 40 GBASE-ER4 100 GBASE-LR4 CFP4. 1.. 40 Gbit/s 100 Gbit/s 1 . 1 CFP 1 . 10 Gbit/s .. CFP 4 2.. QSFP+ 2. CFP4 1. 2 a .
