400 GbE Ethernet cable supports high bandwidths necessary for next-generation cloud services, hyperscale data centers and telecom carriers.
  • OS2-rated cable recommended for 400 Gb speeds up to 2 km (@ 1310 nm)
  • CS connectors 40% more dense than standard LC ends for easier cable management
  • Smaller-format CS ends designed for next-generation 400G QSFP-DD transceivers
  • Backward compatible with 40/100 GbE networks to facilitate future-proofing
  • Yellow LSZH jacket allows fast, easy identification in a crowded switch or patch panel

Features

400 GbE Cable Supports Higher Bandwidths Needed for Next-Gen Data Networking
As the amount of traffic in data networks grows, so does the need for next-generation devices and fiber cables to support much higher bandwidths in cloud services, hyperscale data centers, telecom applications and equipment OEM companies. This duplex singlemode 9/125 OS2 cable is an ideal choice for 400G Ethernet applications up to two kilometers (at 1310 nm). It is also backward compatible with 40 Gb and 100 Gb networks, so you can future-proof your current application for an eventual upgrade to 400 Gb.

Compact CS Connectors Designed for the Latest QSFP-DD Transceivers
The CS ends are 40 percent smaller than standard LC connectors, making them compatible with the latest 400G QSFP-DD transceivers and an excellent solution for high-density network applications. Push/pull tabs allow dense vertical stacking in switches or patch panels where space is at a premium and make the cable easy to install or remove with one hand.

Yellow Jacket Helps Avoid Misidentification That Can Cause Costly Downtime
The OS2-rated cable has a yellow jacket, which is easy to identify quickly in a crowded patch panel or switch and helps prevent the cable from becoming accidentally disconnected. The round low-smoke zero-halogen (LSZH) jacket limits the amount of toxic smoke emitted in case of combustion, making it suitable for poorly ventilated areas. It also complies with G657A2 bend-insensitive fiber standards, which allows for easy installation without excessive care when storing the fiber due to the increased bend radius.
