40/100 GbE Ethernet cable extends high-density connections between network components in enterprise applications in wiring closets, telecom rooms and data centers.

  • OM4-rated cable recommended for 100 Gb speeds up to 100 meters (@ 850 nm)
  • Backward compatible with 10/25/40 Gb networks to facilitate future-proofing
  • Magenta LSZH jacket allows fast, easy identification in a crowded switch or patch panel

Features

40/100 GbE Cable Supports Higher Bandwidths Needed for High-Density Data Networking
The N858B-38M-3X8MG is a premium multimode fiber optic cable that supports 400 Gb Ethernet speeds for transmitting data and voice signals over short distances. It is designed to support higher bandwidths in cloud services, hyperscale data centers, telecom applications and equipment OEM companies. This multimode 50/125 OM4 cable is an ideal choice for 400 Gb Ethernet applications up to 100 meters (328 feet) at 850 nm. It is also backward compatible with 10 Gb, 25 Gb and 40 Gb networks, so you can future-proof your current application for an eventual upgrade to 100 Gb or 400 Gb.

Magenta-Colored Jacket Helps Avoid Misidentification That Can Cause Costly Downtime
The OM4-rated cable has a magenta jacket to identify it as multimode in a crowded patch panel or switch and prevent it 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. The connectors’ slim boots and magenta housings allow easy one-handed installation and removal of the cable.
