With the rapid development of cloud computing, big data and Ethernet, operators have upgraded their data centers to higher data rates, which has further increased the demand for 100G, and the pattern is also shifting from 100G, and 100G QSFP28 ZR4 is also It is the product of this era of big data. This article is mainly about 100G QSFP28 ZR4 optical module product introduction brought by FiberWDM communication.

100G QSFP28 optical modules include SR4, PSM4, LR4, CWDM4, ER4, ZR4, etc. Among them, the 100G QSFP28 ZR4 optical module is mainly used for data center switches, routers, and long-distance transmission connections, using 4 channels of 28G NRZ wavelength division multiplexing Technology (LWDM4), is a 4-channel full-duplex transceiver module, mainly used in 100G Ethernet, data center, telecommunications and other scenarios.

In terms of product characteristics, the 100G QSFP28 ZR4 optical module adopts a hot-swappable QSFP28 package, the operating temperature is 0°C-70°C, and the maximum rate can be as high as 103.125Gbps (4x25G NRZ). After cost optimization, it can achieve up to 80km. When the FEC system is turned on, the transmission distance can be up to 90km through a pair of single-mode optical fibers.

In terms of structure, the 100G QSFP28 ZR4 optical module is at the transmitting end, and the four-channel serial data is recovered by the CDR and transmitted to the four laser drivers. At the receiving end, the optical signal of 4 channels is amplified by SOA, and then the optical signal is demultiplexed by the integrated optical demultiplexer. The recovery of each optical signal is carried out by the PIN detector, and finally transmitted to the CAUI-4 compliant output driver through the transimpedance amplifier and CDR.

In addition, this 100G QSFP28 ZR4 optical module is small in size and low in power consumption. The maximum power consumption is less than 6W. It can provide a point-to-point solution in the data center. RoHS environmental protection standards (lead-free) and QSFP28 MSA and 100G ZR4 Ethernet standards.

The above is the 100G QSFP28 ZR4 optical module introduced by FiberWDM communication. If you have any questions, please contact us, email: sales@fiberwdm.com
