PRODUCT OVERVIEW

This OM3 Duplex Multimode Fibre Optic Cable is ideal for connecting 10GBase-SR, 10GBase-LRM, SFP+ and QSFP+ transceivers for 10 gigabit network connections. This cable has a LSZH jacket which protects from toxic and corrosive gases in poorly ventilated spaces and other areas where it is most critical. This cable also provides backward compatibility with existing 50/125 equipment and the performance headroom required to support LED and VCSEL laser light sources, and 10 Gigabit Ethernet applications.

This part is cataloged in the Federal Logistics Information System (FLIS) under NSN 5999-00-204-5872, indicating validated use in U.S. government and defense logistics supply chains.
