What Ethernet standards can be used with QSFP39?
100 GB Ethernet is the latest technology which provides a stable ground for future high bandwidth requiring applications. The development of new devices like mobile phones, centralized enterprise desktops and cloud solutions are putting pressure in Datacenters for more bandwidth and stability. The QSFP28 optical transceiver has several advantages
Increased front panel density compared to QSFP+ transceiver Increased lane speeds from 10 GB/s to 25 GB/s. Available with VCELS or silicon photonics for longer reach. With the help of silicon photonics Datacenters can reach more than 2 kilometers on Single-mode fibers.
For distance greater than 2 kilometers the 100GBASE-LR4 and 100GBASE-ER4 standards have been developed. This is possible because of the upgraded electrical interface of the QSFP28 compared to QSFP+. Because of this it has
become as easy to deploy a 100 GB Ethernet as deploying 10 GB Ethernet.
