Cisco 400GBASE-DR4 QSFP-DD Transceiver, MPO-12, 500 m Parallel Single-Mode

Parallel single-mode at 500 m: that is the Cisco QDD-400G-DR4-S, titled 400GBASE-DR4. Data lists a QSFP-DD form factor, an MPO-12 APC connector and a 1310 nm wavelength.

It fits data hall and campus links beyond what multimode reaches, with parallel single-mode cabling. The APC connector means patch cords and panels must be APC too, and a plant built around duplex pairs would need changes. Tell us the fiber type, the longest distance and the switch model, and we will check that the module suits the link. Matching patch cords can be added to the same request if you need them.

The module is a single-port unit at 400GbE. Both ends of a link need the same optic type. You can request it in all three conditions. New and refurbished units list 1 year or 3 years of warranty, and used units list 90 days.
