1. The N3951 series is used between transceivers to extend the transmission distance of fiber optical system It magnifies the optical signal received from transmitter and sends it to receiver By using a N3951 the transmission distance of the system is doubled Typical application connection N3784XA 4 N3951 N3784XB 4 Figure 6 Transmission repeater CABLE DIAMETER CALCULATION AND LIGHTNING 8 SURGE Relation between 24VAC Cable Diameter and Transmission Distance In general the maximum allowable voltage loss rate is 1090 for AC powered devices The table below shows the relationship between transmission power and maximum transmission distance under a certain specified cable diameter on condition that the 24VAC voltage loss rate is below 10 According to table if a device rated at 50W is installed 17 meter away from the transformer the minimum cable diameter shall be 0 8000mm A lower diameter value tends to cause voltage loss and even system instability Diameter en en 0 8000 1 000 1 250 2 000 o me son mew wen AT T T mem nam e men mos men mann se sm sen sea _ TTT ow sen 1900 soon _ sw sem wen mes _ men _ w nen mo so wo _ _ so wmo _ we o mon _ se fso vw mo e n mo _2. _ seo _ w o sen _ Lightning amp Surge Protection The product adopts multi level anti lightning and anti surge technology integrated with gas discharge tube power resistor and TVS tube The powerful lightning and surge protection barrier effectively avoids product damage caused by various pulse signals with power below 4kV including instantaneous lightning surge and static However for complicated outdoor environment refer to instruction below for lightning and surge protection The product features with dedicated earth wire which must be firmly grounded As for surveillance sites beyond the effective protection scope it s necessary to erect independent lightening rods to protect the security devices It s recommended to separate the lightning rod from the mounting pole placing the rod on an independent pole as shown in the figure below If the product has to be installed on the same pole or pedestal for lightning rod there should be strict insulation between the video cable BNC terminal power cable control cable and the standing pole of the lightning rod For suburb and rural areas it s recommended to adopt direct burial for the transmission cables Overhead wiring 15 prohibited because it s more likely to encounter lightning strike Use shielded cables or thread the cables through metal tubes for burial thus to ensure the electric connection to the metal tu
