Cisco 4x100GBASE-FR1 QSFP-DD Transceiver, MPO-12, 2 km Parallel Single-Mode

The 4x100G in the name of the Cisco QDD-4X100G-FR-S points to four 100G channels in one QSFP-DD module. The title gives 4x100GBASE-FR1, MPO-12 APC, parallel single-mode and a 2 km reach, and the wavelength is 1310 nm.

Buyers choose a part like this to run a 400G port as four separate 100G links over parallel fiber. Verify the other end of each channel supports a matching 100G optic, and that the patching is MPO-12 APC. Tell us what the far end uses for each of the four channels and the switch model on this side, and we will confirm that the whole link is covered. Matching patch cords can be added to the same request.

The module has a single port and fits QSFP-DD cages. It is offered new or refurbished. Both conditions carry a choice of 1 year or 3 years of warranty.
