40G QSFP+ Single Mode Transceiver Overview

The 40G QSFP+ optical communication module launched by Sintai Communication Co., Ltd. is specifically designed for 40G Ethernet and 40G OTN applications. 


The module conforms to the QSFP+ MSA standard and IEEE 802.3ba standard ad supports a maximum rate of 44.6Gb/s, with digital diagnostic capabilities. 

The product contains two kinds' modules: single-mode module and multimode module. 


The single-mode module is equipped with MUX/DEMUX devices, and it uses wavelength division multiplexing technology to multiplex the 4 x 10Gb/s CWDM channel on a single optical fiber, with the longest transmission distance of up to 40km. It's widely used in environments such as large data centers, campus networks, metro networks, etc.
