Frequently Asked Questions
What is a QSFP-DD transceiver and why is it used in data centers?
A QSFP-DD (Quad Small Form-factor Pluggable Double Density) transceiver is a compact optical module that supports 400Gb/s data rates. The QDD-400G-LR4-ENC is ideal for data centers because it maximizes port density on network switches while delivering the extreme bandwidth required for server-to-server communication, storage area networks, and inter-data-center connectivity.
What does 400GBASE-LR4 mean and what are its advantages?
400GBASE-LR4 is an IEEE standard for 400Gb/s transmission over long-reach single-mode fiber. The LR4 designation means it supports extended distances (typically 10km) using four wavelengths, making it perfect for campus networks and metropolitan area connections without requiring expensive amplification equipment.
Is the ENET QDD-400G-LR4-ENC compatible with my existing network infrastructure?
The QDD-400G-LR4-ENC uses industry-standard 400GBASE-LR4 specifications and duplex LC connectors, ensuring compatibility with modern data center switches and routers that support QSFP-DD modules. Verify your network equipment supports QSFP-DD form factor and 400GBASE-LR4 standard before deployment.
What transmission distances can I achieve with this 400Gb/s optical transceiver?
The QDD-400G-LR4-ENC supports long-reach transmission over single-mode fiber, typically achieving distances up to 10 kilometers. This makes it suitable for data center interconnects, campus networks, and metropolitan area networks without requiring optical amplifiers.
