40G QSFP+ Multimode 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 transmitting end of the multimode module adopts the 4 X 10Gb/s 850nm VCSEL laser array, the receiving end uses 4xPIN optical detector array, and the transmission distance is 300 meters when OM3 multimode fiber is used and the transmission distance is 400 meters OM4 multimode fiber is used. It's widely used in environments such as large data centers, campus networks, metro networks, etc.
