Plastic Optical Fiber Cable and Accessories for Versatile Link Technical Data HFBR-RXXYYY Series (POF) HFBR-EXXYYY Series (POF) Features Cable Description Compatible with Agilent The HFBR-R/EXXYYY series of Versatile Link Family of plastic fiber optic cables are Connectors and Fiber Optic constructed of a single step-index Components fiber sheathed in a black poly- ethylene jacket. The duplex fiber 1 mm Diameter Plastic consists of two simplex fibers Optical Fiber (POF) in Two joined with a zipcord web. Grades: Low Cost Standard POF with 0.22 dB/m Typical Standard attenuation and extra Attenuation, or High low loss POF cables are identical Performance Extra Low Loss except for attenuation POF with 0.19 dB/m Typical 500 specifications. Attenuation Polyethylene jackets on all plastic 400 Applications fiber cables comply with UL VW-1 Industrial Data Links for flame retardant specification (UL 300 Factory Automation and file E89328). Plant Control Intra-System Links Board- Cables are available in 200 to-Board, Rack-to-Rack unconnectored or connectored Telecommunications options.

Installation temperature is the range over which the cable can be bent and pulled without damage. Below -20C the cable becomes brittle and should not be subjected to mechanical stress. 2. Short Term Tensile Force is for less than 30 minutes. 3. Short Term Bend Radius is for less than 1 hour nonoperating. 4. 90 bend on 25 mm radius mandrel. Bend radius is the radius of the mandrel around which the cable is bent. 5. Typical data are at 25C. 6. Propagation delay constant is the reciprocal of the group velocity for propagation delay of optical power. Group velocity is v=c/n where c is the velocity of light in free space 8 (3xl0 m/s) and n is the effective core index of refraction. 7. Note that rises at the rate of about 0.0067 dB/C, where the thermal rise refers to R the LED temperature changes above 25C. Please refer to Figure 1 which shows the typical plastic optical fiber attenuation versus wavelength at 25C.
