Cisco 2x100G-CWDM4 QSFP-DD Transceiver, Dual Duplex CS, 2 km Single-Mode

Dual duplex CS connectors identify the Cisco QDD-2X100-CWDM4-S. The title reads 2x100G-CWDM4, the form factor is QSFP-DD, the fiber is single-mode and the reach is 2 km.

Two duplex pairs, each carrying a 100G link, come out of one module. CS is a compact connector, so verify that your panels and patch cords use it; a conversion cord is the fallback if they do not. Tell us what the far end of each channel uses and the switch model on this side, and we will confirm that the whole link is covered before you order.

Plan the far end of both channels before you order, since each needs a matching 100G optic. This CWDM4 is offered in new, refurbished and used condition. Warranty is 1 year or 3 years for new and refurbished, and 90 days for used.
