100G QSFP28 Multimode Transceiver Overview

The 100G QSFP28 optical communication module launched by Sintai Communication Co., Ltd. contains the 100GBASE-SR4 and 100GBASE-LR4 series and supports a maximum rate of 103.1Gb/s. 

This series of products use LC or MPO optical port and they are compatible with IEEE802.3ba standard and SFF-8636 standard; with characteristics of low power consumption, small volume, and high speed, it is advantageous to the data center to increase capacity, improve port density and reduce power consumption. 

It's mainly used in environments such as internal networks of 100G data centers, data center interconnection, and metro area networks. The transmitting end of the 100G QSFP28 SR4 module adopts the 4X25Gb/s 850nm VCSEL laser array, the receiving end uses 4xPIN optical detector array, and the transmission distance is 100 meters when OM4 multimode fiber is used.
