Product Overview
The 40G QSFP+ optical communication module launched by Guangdong Global Telecommunication Technology 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 44.6 Gb/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 4X10Gb/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; the single-mode module is equipped with MUX/DEMUX devices, and it uses wavelength division multiplexing technology to multiplex the 4x10Gb/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.
