Since data centers have been experiencing an great infrastructure change to achieve higher levels of performance and scalability, the demand for 100G Ethernet network increases day by day. To better accommodate this great change, there are several kinds of transceivers designed for deploying 100G Ethernet network, such as, CFP, CFP2, CFP4, QSFP28, CPAK, etc. Among these 100G optics, QSFP28 transceiver offers the optimal solution for the 100G migration with the lowest power consumption which is very commonly used at present. In this paper, it will introduce QSFP28 transceiver and analyze the reason why QSFP28 transceiver is so popular in 100G Ethernet network.
QSFP28 Transceiver Overview
As the smallest 100G form factor transceiver, QSFP28 transceiver has the same size and lane number as 40G QSFP+ transceiver, which is implemented with four 25-Gbps lanes to achieve 100G transmission. With the design of an upgraded electrical interface, it is able to support signals rates up to 28 Gbit/s
