Sumitomo Electric starts supplying sample 40 Gbit/s 4-wave integrated optical receivers

40 Gbit/s 4-wave integrated optical receiver for optical communication application

Sumitomo Electric has recently developed a 40 Gbit/s 4-wave integrated optical receiver and started to supply sample units. Consisting of an optical branching filter, photodiode, and transimpedance amplifier elaborately integrated into a very small package, the newly developed optical receiver achieves a high receiving sensitivity and a transmission speed four times higher than conventional 10 Gbit/s transmission receivers of the same size.

The new receiver complies with both Telecom (ITU-T ※1 ) and Datacom (IEEE ※2 ) standards for 40 Gbit/s data transmission, enabling its use for QSFP+ ※3 and other applications.

※1ITU-T:
International Telecommunication Union Telecommunication Standardization Sector
※2IEEE:
Institute of Electrical and Electronics Engineers
※3QSFP+:
an industry standard for 40 Gbit/s small optical transceivers
