ADD-LC-LC-20M5OM4 is a 20m Laser-Optimized Multi-Mode fiber (LOMM) Duplex LC/LC OM4 Aqua Patch Cable. This high quality LOMM (50/125) patch cable is specifically designed for 40Gb ethernet, multimedia, or communication applications, and provides extended bandwidth over OM3 cable. This patch cable is suited for shorter reach data center LAN's or SAN's, and is recommended for connection between fiber patch panels, hubs, switches, media converters and routers, etc. The Low-Smoke Zero-Halogen(LSZH) jacket protects from toxic and corrosive gases in badly ventilated spaces and other areas where it is most crucial. It is designedto enhance the system cost benefits enabled by 850 nm Vertical Cavity Surface Emitting Lasers (VCSELs) for existing 1 and 10 Gb/s applications, as well as future 40 and 100 Gb/s systems. When used at less than rated distance environments, the high bandwidth provided by OM4 fiber provides extra headroom for channel insertion loss. AddOn Patch Cables are 100% RoHS compliant for all of your networking needs. They provide higher speeds and increased bandwidth, compared to conventional twisted-pair copper cable. Each cable is 100% optically tested for insertion loss before you take ownership. Now you have a cost effective solution to your network upgrade needs. AddOn products are guaranteed.
