The Cisco QDD-400G-LR4-S= is a 400G QSFP-DD transceiver using 400GBASE-LR4 over single-mode fiber. It uses a duplex LC connector and is rated for reaches of up to 10 km over single-mode fiber. The QSFP-DD form factor is used for 400G ports. They are used to build or extend uplinks, and the media type and reach should match the link design. Check that the host switch or router supports this optic before ordering. We can quote QDD-400G-LR4-S= for Dubai and wider UAE projects.
