Sm(Single-mode) Simplex Riser(OFNR-Optical Fiber Nonconductive Riser, BIF 1.6mm, LC/APC-SC/UPC,5 meters long; UL Listed
Sm(Single-mode) Simplex-Singlemodeis typicallyused inlong-haul network connections spread out over extended areas--longer than a few miles. For example, telcosuseit for connections between switching offices.Singlemodecable features a 9-micron glass core.Asimplex fibercable consists of a single strand of glass of plasticfiber.Simplex fiberis most often used where only a single transmit and/or receive line is required between devices or when a multiplex data signal is used (bi-directional communication over a singlefiber).
Riser OFNR-Optical Fiber Nonconductive Riser-OFNRrefers to thefiberrating of thecablejacketing.OFNRis the designation given by the National Fire Protection Association (NFPA) to interiorfiber-optic cableswhich contain no electrically conductive component, and which are certified for use in Riser applications.
BIF-Bend Insensitive Fiber- This fiberadds a layer of glass around the core of thefiberwhich has a lower index of refraction that literally "reflects" the weakly guided modes back into the core when stress normally causes them to be coupled into the cladding. This fiber can be stapled or bent around corners and is used as part of the fiber backbone between floors of buildings that house call centers.
LC/APC-SC/UPC Connectors
LC/APC-LC or Lucent Connectors are about half the size of SC connectors, 1.25mm diameter ferrule. APC stands forAngled Polished connector, which prevents back-reflections. It is usually used in analog fiber optic system equipment,such as CATV or Satellite. These connectors are green in color over jacketed boots.LC/APC connectors are specially designed to provide low insertion loss and back reflection, along with high precision and mechanical stability.
SC/UPC Connectorsadopt an extended polish method to realize finer fiber surface finish, whichbrings much lower back reflection (ORL) and thus provides much more reliable signal in datacenter, digital TV and telephone. They are blue in color with white jacketed boots.
