The N484-3M8L12S 9/125 Singlemode Fiber Optic 40/100 Gb to 10/25 Gb Breakout Cassette works in tandem with the N484-01U or N484-00U chassis (sold separately) to join 12 duplex LC fiber cables with three 8-fiber MTP/MPO connections. Ideal for interconnecting any combination of 10 Gb, 25 Gb, 40 Gb and 100 Gb network equipment in a simple, elegant and highly flexible way, it’s compatible with recommended cabling, including the N370- and N390-Series. Its 8-fiber MTP ports are Polarity B, optimized for parallel optics and Base-8 connectivity.The fiber optic cassette installs easily in the N484-01U and N484-00U chassis with no tools required. Just insert the cassette into the chassis, and tighten its retention clips to secure it. Plug LC Ethernet cables, such as N370- and N390-Series cables (sold separately), into the cassette using the cables’ convenient push/pull tabs. Up to four cassettes fit into the N484-01U 1U enclosure panel, and one cassette fits into the N484-00U 0U sleeve. Dust tabs protect unused ports from potential damage.The modular design makes it easy to modify, upgrade or expand your infrastructure as your needs grow. If you need to change out a single cassette, you can do so without replacing the panel or removing other cassettes. Because this system supports devices of varying speeds, you can mix and match 10 Gb, 25 Gb, 40 Gb and 100 Gb network equipment. The fiber cassette supports 40/100 GbE internally using singlemode fiber optic cables and is ideal for QSFP fabric switches that use eight out of 12 available MTP fibers for four-lane parallel optics to 40/100 Gb.The N484-3M8L12S complies with IEEE 802.3ae (10 GbE) and ANSI T11.2 (Fibre Channel) requirements. Maximum insertion loss of 0.35 dB falls well under the IEEE 802.3ae maximum channel loss specification of
