Data Center Interconnect (DCI) refers to the data transmission between two or more data centers. These data centers can span the campus area(<20km), metropolitical area (20km - 80km) and ultra long distance (80km - 2000km above). With more and more enterprises places the services & application to the Cloud, the Cloud data center generates the explosive east-west data traffic and stimulates the demand on the high capacity and high bandwidth data center interconnect. In those hyper scale data center, 100G network plays an important role for the DCI applications between Metro and regional facilities. 


Top-Trans QSFP28 100G Module is designed for 100GBASE DCI application within the distance of 40KM. This QSFP28 ER4 module uses EML transmitter and APD receiver to create the 100Gigabit connection via the fiber link over up to 40KM in the G.652 OS2 Singlemode Fiber. This QSFP28 module features the LC duplex connector which can interoperate with other QSFP28 ER4 optics. This QSFP28 module is fully MSA compliant and features the online DOM/DDM to monitor the operation status. This QSFP28 module can be programmed with the compatibility to interoperate with Arista Network QSFP28 ports.
