Juniper QDD-8X50G-2P5M 400G DAC Breakout 2.5 m | QSFP-DD, 8x50G

When short-reach connectivity needs a little more room, the QDD-8X50G-2P5M provides a 2.5 m copper breakout path from one 400G port to 8 x 50G endpoints. It is designed for infrastructure teams that want to keep the simplicity of direct attach copper while accommodating slightly longer routing between adjacent racks or equipment rows. The value is in the balance: enough length to cleanly route around cable managers and rack hardware, but still short enough to avoid the cost, power, and operational overhead of optical links. For high-density environments, that means fewer moving parts in the signal path and a more predictable installation experience. This breakout cable is well suited to Juniper-based fabrics where a single high-speed interface must serve multiple 50G connections. It supports structured port planning in leaf-spine networks, lab rows, and aggregation layers where copper remains the right answer for short distances. Choose the 2.5 m version when the topology is still close, but the cable path is not. It gives you the reach to route cleanly without giving up the direct, low-complexity design that DAC is known for.
