FAQ

Ask a Question

Find answers to common questions about our products.

Can I use this 400G QSFP-DD DR4 module to connect to 100G DR modules?

Yes. AICPLIGHT 400G QSFP-DD DR4 can support 400G-to-4x100G breakout when the switch port supports breakout mode. Use an MPO/MTP-12 APC to 4xLC single-mode breakout cable with compatible 100G DR modules.

Is this module suitable for upgrading a 100G network over more than 500m?

Not directly. This DR4 module is designed for links up to 500m, so for longer 100G breakout links, a 400G XDR4-to-4x100G FR solution is usually more suitable.

Can QSFP-DD 400G DR4 interconnect with OSFP or QSFP112 400G DR4 modules?

Yes. QSFP-DD, OSFP, and QSFP112 are different host-side form factors, but if both ends use the same 400G DR4 optical standard, they can interconnect over single-mode MPO/MTP-12 APC fiber.

Can I plug this QSFP-DD DR4 module into an OSFP, QSFP56, or QSFP28 port?

No. QSFP-DD modules must be used in QSFP-DD ports. A QSFP-DD port may accept lower-speed QSFP modules in some platforms, but QSFP-DD modules cannot be inserted into QSFP56 or QSFP28 ports.

Why does QSFP-DD DR4 use 4 optical lanes if QSFP-DD is 8x50G on the host side?

On the host side, QSFP-DD typically uses 8x50G electrical lanes. Inside the module, the DSP gearbox converts these electrical lanes into 4x100G PAM4 optical lanes for DR4 transmission.
