Offex 2 Fiber Indoor/Outdoor Fiber Optic Cable, Multimode, 50/125, OM3, 10 Gbit, Black, Riser Rated, Spool, 1000 footCategory: 10 Multimode Fiber OpticThis is a black bulk 1000 foot spool of indoor/outdoor rated fiber optic distribution cable intended for large installations of short range runs at 10 Gigabit speeds. It is composed of 2 multimode fibers (50 micron core) inside a water blocking Aramid yarn wrapped in a black PVC outer jacket. Multimode fiber is optimized to work with fiber optic equipment using light wave lengths of 850nm (nanometers) or 1300nm. The cladding diameter is 125 microns. The Graded-Step core and cladding of our black bulk 50/125 indoor/outdoor fiber optic cable is constructed using a high quality multimode fiber that is compliant with TIA/EIA 455-220A and IEC 60793-1-49. It also maintains compliance with legacy and LED based systems per TIA/EIA 455-204 and IEC 607-1-41. This particular cable is Riser Rated (CMR) meaning it complies with UL-1666. It is for usage in vertical tray applications without environmental air. Examples being: cable runs between floors through cable risers or in elevator shafts. These cables self extinguish and prevent the flame from traveling up the cable in a vertical burn test. This fiber optic cable is solidly constructed, UL rated and RoHS Compliant. Offex Indoor/ Outdoor Cable is composed of 2 to 24 colored tight buffers, water blocking aramid yarn, and a UV resistant black PVC outer jacket. All component materials meet the EU RoHS and REACH Directive standards. CWS Distribution Cable is available in 12 TIA standard colors or special order colors. UL Listed OFNR cables are available, and unlisted, unrated cables can be supplied to accommodate special needs. Standard surface print denotes construction, NEC rating, and fiber type, and includes footage markers. Custom print can also be accommodated.
