Frequently Asked Questions
What is a 400GBASE-LR4 QSFP-DD transceiver used for?
The 400GBASE-LR4 QSFP-DD transceiver is designed for high-speed, long-distance data center interconnects and metropolitan area networks. It enables 400 gigabit per second connectivity over single-mode fiber up to 10 kilometers, making it essential for enterprise backbone networks and campus fiber links requiring ultra-high bandwidth.
How does CWDM technology improve 400Gb/s transmission?
CWDM (Coarse Wavelength Division Multiplexing) allows the ENET transceiver to transmit four separate data channels simultaneously on different wavelengths (1271nm, 1291nm, 1311nm, 1331nm) over a single fiber pair. This efficient wavelength management maximizes fiber utilization and enables 400 gigabit speeds without requiring multiple fiber strands.
Is the ENET QDD-400G-LR4-10-ENC compatible with standard data center infrastructure?
Yes, the QSFP-DD form factor and duplex LC connector ensure compatibility with modern data center switches and routers supporting 400GBASE-LR4 standards. The hot-swappable design allows for easy installation and replacement without network downtime.
What transmission distance does this 400Gb/s optical transceiver support?
The ENET QDD-400G-LR4-10-ENC supports transmission distances up to 10 kilometers over single-mode fiber, making it suitable for long-reach applications including campus interconnects, metropolitan networks, and extended data center links.
