Overview The N484-3M8-LC12 40 GB to 10 GB Breakout Cassette works in tandem with Tripp Lites N484-01U or N484-00U chassis to connect 12 LC duplex fiber cables with three 8-fiber MTP/MPO connections in high-density network applications. Its compatible with recommended Tripp Lite cabling, including the N820-, N821-, N844- and N858 Series. Its 8-fiber MTP ports are Polarity B, optimized for parallel optics and Base-8 connectivity. The cassettes modular design installs easily in the N484-01U and N484-00U chassis with no tools required. Just insert the cassette into the chassis, and screw in its retention clips to secure it. Plug LC patch cables, such as Tripp Lites N820-01M-T cables, into the cassette using the cables convenient push/pull tabs. Up to four N484-3M8-LC12 cassettes fit in the N484-01U 1U enclosure panel, and one cassette fits in the N484-00U 0U sleeve. Dust tabs protect unused ports from potential damage. The N484-3M8-LC12 complies with IEEE 802.3ae (10 GbE) and ANSI T11.2 (Fibre Channel) requirements. Supports 40 GbE internally using OM4 fiber optic cable. Ideal for QSFP fabric switches that use eight out of 12 available MTP fibers for four-lane parallel optics to 40 GB, allowing all 12 LC duplex cassette ports to be used. Maximum insertion loss of 0.35 dB falls well under the IEEE 802.3ae maximum channel loss specification of <25 dB. This cassette also supports devices of varying speeds, including 10 GB and 40 GB network equipment.
