The emergence of cloud services, AI applications and 5G has accelerated the need for faster data rates and larger bandwidths in core networks. To satisfy this advancing demand and provide a cost-effective solution, QSFP28 PAM4 was introduced as one of the most reliable tools to achieve 100G data rates and 400G capabilities with greater port density, lower power consumption and less expensive associated costs. First developed in 2016, PAM4 QSFP28 DWDM supports transmission over 80km for both 100G and 400G metro network applications. As an ideal data communication solution for such high-bandwidth requirements, it offers unparalleled speed, capacity and efficiency that can bring great value to businesses looking for the most cutting edge technology to maximize their productivity.
PAM4, also known as Pulse Amplitude Modulation 4-level, is a major optical transmission technology that packs two bits of data into four distinct signal levels. It doubles the signal bandwidth of an optical connection, thus doubling its data rate with minimal degradation. 100G and 400G transceivers capitalize on PAM4 by encoding 100G signals in the conveniently small QSFP28 form factor. 100G PAM4 transceivers feature advanced dimensionality modulation and are the most effective way to maximize data throughput while reducing cost. To better understand how PAM4 works, it’s helpful to visualize it compared with NRZ: PAM4 doubles the data rate with four signal levels instead of two, so your network can be running faster than ever in no time!
How Does PAM4 QSFP28 Perform As a Solution for 100G/400G?
With pam4-qsfp28 DWDM technology, companies are gaining new options for extending 100G/400G signals. This evolving solution has a number of conveniences that can be exploited to maximize data transfer and operations. One of the greatest benefits associated with pam4-qsfp28 DWDM is it’s large data capacity ability, providing up to 4.8Tb/s over single mode fiber (SMF). Furthermore, beyond its adept capacity for transfers, pam4 can often reduce data degradation. PAM4 qsfp28 also activates lower power consumption thresholds per each high speed transmitted signal. In addition to quality efficiency, pam4-qsfp28 is conveniently embedded with DWDM allowing pluggability into data center routers or switch portals a much easier process compared to traditional methods. Without pam4-qfsfp28 these doorways between extended 100G/400G signals would become more complex to access due to their significance in today’s faster networks and centers.
QSFPTEK‘s 100G DWDM QSFP28 PAM4 solution is the superior choice for expanding global networks, as its pam4 qsfp28 transceivers use advanced PAM modulation to facilitate high transmission speeds of up to 100G through a single mode fiber CS connector with reliably low power consumption. These cost-effective pam4 QSFP28 equipments can be easily integrated into current 1G/10G networks, allowing users to upgrade their setups to higher data rates while saving energy costs at the same time! With pam4 qsfp28, global communications will reach unprecedented levels of speed and efficiency – making it an invaluable asset in today’s interconnected world.
