Models 5843, 5844, 5843S and 5844SRS-232 or TTL3-63.7 SELECTION OF FIBER OPTIC CABLE (FOC)Fiber optical cable is available in several formats; simplex, duplex, and breakout. FOC isalso available in various diameters and tensile strengths. Tensile strength is important forlonger life expectancy.Simplex FOC is desirable for loop operations. It has one optical conductor and can beconnected from the transmitter of one Link/Repeater to the receiver of the nextLink/Repeater in the loop.Duplex FOC has two optical conductors and is a convenient form when connecting twounits Point-to-Point.Breakout cable is a duplex FOC that has extra strength members added and is suit-able for burial.The following are the specifications of multi-mode FOC offered by DYMEC and is the recommendedminimum standard for optimum performance.METRIC-TO-ENGLISH UNIT CONVERSIONSMULTIPLYBYMULTIPLYBYMillimeters →→→→ Inches 0.03937 Kilograms →→→→ Pounds 2.2046Centimeters →→→→ Inches 0.3937 Kg/Km →→→→ Pounds/1,000 Ft 0.67197Meters →→→→ Feet 3.2808 Newtons →→→→ Pounds 0.22481Kilometers →→→→ Feet 3280.8 N/Cm →→→→ Pounds/inch 0.57101Kilometers →→→→ Miles 0.62137Simplex Duplex BreakoutFiber Count 1 2 2Fiber Material Glass Glass GlassAttenuation [dB/km] 3 3 3Diameter [mm] 3.0 3.0 x 6.5 7.0Weight [kg/km] 8.0 16.0 50Tensile load - Short Term [N] 500 1000 1200Tensile load - Long Term [N] 300 500 500Minimum Bend Radius - With Load [cm] 5 5 14Minimum Bend Radius - No Load [cm] 3 3 7Crush Resistance [N/cm] 750 750 2200Impact Resistance [Cycles] 1000 1000 2500Flex Resistance [Cycles] 7500 7500 2000Operating Temperature [oC] -40o to +85o -40o to +85o -40o to +85oStorage Temperature [oC] -55o to +85o -55o to +85o -55o to +85o |
