Loose Tube OM3 50/125 Multimode Fiber Optic Cable, Riser OFNR

This riser dry loose tube fiber cable is composed of one to six sub-units, water blocking yarn, an optional central strength member, water blocking tape (only for 72 fiber), an aramid ripcord, and a PVC outer jacket. Each sub-unit consists of 12 colored glass fibers and water swellable yarn with a PVC jacket 3mm in diameter. All component materials meet the EU RoHS and REACH Directive standards. Sub-units can be color-coded or sequentially numbered.

This riser dry loose tube fiber cable is available in 12 TIA standard colors or special order colors. The fiber cable is UL Listed OFNR for use in vertical runs in building riser shafts or from floor to floor. Standard surface print denotes construction, NEC rating, and fiber type, and includes footage markers. Custom print can also be accommodated.

Cleaning your fiber connector end faces and components regularly is crucial for avoiding a total network failure. Ensure your optical fiber system is working properly and prevent major network issues with fiber cleaning kits, pens, fluids, and wipes.

Additional Information

Multi-Mode cable commonly has a diameter in the 50-to-100 micron range (typical multimode fiber core diameters are 50 or 62.5 micrometers). Multimode fiber gives you high bandwidth at high speeds (10 to 100MBS - Gigabit to 275m to 2km) over medium distances. Light waves are dispersed into numerous paths, or modes, as they travel through the cable's core typically 850 or 1300nm. However, in long cable runs (greater than 3000 feet [914.4 meters), multiple paths of light can cause signal distortion at the receiving end, resulting in an unclear and incomplete data transmission so designers now call for single mode fiber in new applications using Gigabit and beyond.
