Discover the QDD 400G DR4 optical transceiver modules, compatible with Cisco and Juniper. Enjoy 500m link lengths with QSFP-DD connectors for enhanced performance.
DR (Distance Range): Up to 500 meters, using single-mode fiber for inter-data center links. FR (Long Range): Up to 2 kilometers, using single-mode fiber for longer network connections.
What is the main difference between DR4 and FR4? DR4 uses MPO parallel fibers for short distances, while FR4 uses CWDM over LC for longer reach and higher fiber efficiency.
One such type is 400G DR4. 400G DR4 is commonly employed for high-speed communication links within a data center at short to medium distances. In practice, the DR4 type is
On the transmit side, the DR4 transceiver converts 8 channels of 50Gb/s (PAM4) electrical signals into 4 parallel optical channels, each running at 100Gb/s,
