QSFP-DD 400G-ZR 120km Coherent Tunable DWDM Transceiver Module
400GBASE-ZR QSFP-DD 120km Tunable DWDM Coherent Transceiver for Data Center Interconnection (120 km, 49 Channels, 100GHz Grid, C-Band, LC-Duplex, Singlemode)
What is 400G ZR?
400G ZR is a simple and low cost standard for transmitting 400 gigabit Ethernet over data center interconnection links up to 100 km using DWDM (dense wavelength division multiplexing) and higher order modulation such as 16 QAM. The solution is proposed to be available in a small form factor modules such as OSFP or DD-QSFP.
Why is 400G ZR important?
400G ZR reduces cost and complexity for high bandwidth data center interconnects. Higher order modulation and DWDM unlock high bandwidth, but typically require proprietary coordination at both ends of the fiber. With 400G ZR, you can mix-and-match modules at both ends, something that was previously impossible.
How to use 400G ZR?
Use 400GBASE-ZR QSFP-DD transceiver for 120km or less, amplified, point-to-point, DWDM noise limited link.
