Black Box Corporation. 50-Micron Multimode Duplex Fiber Optic Cable Get more bandwidth, more speed, and more distance with these cables. 02/25/2010 1 of 4 26035OVERVIEW Holler if you like having greater amounts of bandwidth. The 50-Micron Multimode Duplex Fiber Optic Cables feature two Features We hear you. 900-m TBII buffered fibers surrounded by aramid yarn that protects Provides three times the bandwidth Thats why Black Box brings you 50-Micron Multimode Duplex the fibers from crushes and bends. Ceramic connectors provide low of 62.5-micron fiber cables. Fiber Optic Cables. These cables provide three times the bandwidth signal loss, high reliability, and extra durability. In addition, the cables Greater performance over longer distances. of 62.5-micron cables That means you get reliable performance over have a flame-retardant jacket. long distances. Like all fiber optic cables, our 50-micron solutions provide total Built for todays and tomorrows Speaking of distance, these cables support longer link lengths than immunity to electrical interference. They meet National Electrical high-speed networks. 62.5-micron cable at 850 nm. While 62.5-micron fiber cables support Code (NEC ) requirements, and are listed as Type OFNR Ceramic connectors provide low signal loss, 850-nm links up to 220 meters (721.8 ft.), our 50-Micron Multimode and CSA FT-4. high reliability, and long life. Duplex Fiber Optic Cables can be used in links as long as 550 meters Two 900-m buffered fibers are surrounded (1804.5 ft.) by aramid yarn and PVC jacketing. Our 50-micron fiber cables are built for todays and tomorrows technically speaking Immune to EMI/RFI. networks. Theyre perfect for Ethernet, storage area networks, high-speed parallel optics interconnects, and other high-speed/ As a general rule, use ceramic ferrules (used in the high-capacity interconnect applications. This is the fiber cable youll 50-Micron Multimode Duplex Fiber Optic Cables) for critical want to have for emerging technologies. network connections, such as backbone cables or for connections that will be changed frequently. Ceramic ferrules are more precisely molded and fit closer to the fiber, which gives the fiber optic cables a lower optical loss. technically speaking As todays networks expand, the demand for The big difference between 50-micron and 62.5-micron more bandwidth and greater distances increases accordingly. cable is in bandwidth50-micron cable features three times the Thus, there is a renewed interest in 50-micron fiber optic cable. bandwidth of standard 62.5-micron cable. At 850 nm, its rated Although introduced in 1976, 50-micron cable has not at 500 MHz/km versus 160 MHz/km. The 850-nm wavelength is experienced the widespread use in North America that 62.5- becoming more important as lasers are being developed and used micron cable has, which was introduced in 1986. more frequently as light sources for networks. These cables share many characteristics. Although 50-micron Other differences are distance and speed. The bandwidth an fiber cable features a smaller core, which is the light-carrying application needs depends on the data transmission rate. Usually, portion of the fiber, both 50- and 62.5-micron cable use data rates are inversely proportional to distance. As the data rate the same glass cladding diameter of 125 microns. Because they goes up (MHz), the distance that rate can be sustained goes have the same outer diameter, both types of cable are equally down. So a higher fiber bandwidth enables you to transmit at strong and are handled in the same way. Also, 50-micron cable a faster rate or for longer distances. In short, 50-micron cable and 62.5-micron cable both use LED and laser light sources. provides longer link lengths and/or higher speeds in the 850-nm As with 62.5-micron cable, you can use 50-micron fiber in all wavelength. For example, the proposed link length for 50-micron types of applications: Ethernet, FDDI, 155-Mbps ATM, Token Ring, cable is 550 meters versus 220 meters for 62.5-micron cable. Fast Ethernet, and Gigabit Ethernet. It is recommended for all premise applicationsbackbone, horizontal, and intrabuilding connectionsand it should be considered especially for any new construction and installations. 02/25/2010 724-746-5500 blackbox.com 2 of 4 26035 BLACK BOX
