FAQ
What is the difference between PAM4 and NRZ modulation?
PAM4 (Pulse Amplitude Modulation 4-level) uses four signal levels, allowing it to transfer 2 bits per symbol compared to NRZ (Non-Return to Zero), which only transfers 1 bit per symbol. This allows PAM4 to double the data rate without increasing the signaling frequency.
How do I know which type of fiber to choose for my application?
If you are deploying over short distances (up to 100 meters), multimode fiber with MPO/MTP connectors is typically the best choice. For longer distances, especially in telecommunications or long-haul networks, singlemode fiber with Duplex LC connectors is recommended.
Can I use these transceivers with my existing QSFP equipment?
The QSFP-DD transceivers are backward compatible with QSFP+ and QSFP28 ports, but your equipment must support QSFP-DD for full compatibility. Please consult your equipment specifications to ensure compatibility.
How long will my order take to ship?
These products are stock items with an estimated lead time of 7 to 10 business days, but if you require faster shipping, please reach out to our customer support for assistance.
