40/100/400 GBE CABLE SUPPORTS HIGH BANDWIDTHS FOR HIGH-DENSITY DATA NETWORKING: The N845-02M-4S-MG is a premium multimode fiber optic cable that supports 400 Gb Ethernet speeds for transmitting data and voice signals over short distances. 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 OM4 breakout cable is an ideal choice for 400 Gb Ethernet applications. 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 SN CONNECTOR DESIGNED FOR THE LATEST OSFP/QSFP-DD TRANSCEIVERS: One cable end features SN connectors, which are four times smaller than a standard duplex LC connector and provide individual and independent duplex fiber breakout at a quad-style OSFP/QSFP-DD transceiver. The push/pull boots encourage dense vertical stacking within a crowded patch panel or switch and make the cable easy to install or remove with just one hand. Switchable SN/PC duplex ends let you make quick polarity changes in the field without tools or the need to re-terminate the connectors. 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.
