Laser Link III 1310 nm Transmitter Installation Booklet 3 1 Chapter 3 Activating the 1310 nm Transmitter Overview Continued RF Signal Due to the characteristic attenuation of the cable normally used between the Input Slope headend combiner network and the optical transmission equipment a sloped RF input is often obtained The 1310 nm Transmitter module is designed to compen sate for 5 dB of cable loss approximately 100 feet Procedure If a tilt is present adjust the highest utilized frequency s RF level to the proper level shown in the RF signal input diagram Connect the spectrum analyzer according to the following procedure laser the highest frequency carrier carrier is at the proper level 11 5 dBmV for 79 NTSC channels 4 Adjust the slope control to obtain a flat response at the desired level KNEE o s nance Continued on next page 3 2 Laser Link III 1310 nm Transmitter Installation Booklet 711970001 Chapter 3 Activating the 1310 nm Transmitter Overview Continued Operation with Reduced Channel Load RF Signal Input Diagram Operation with Increased Channel Load 711970001 The RF input level to the 1310 nm Transmitter can be increased with a reduced channel load to take advantage of an improved carrier to noise ratio CNR This is often desirable in supertrunk applications using split band operation The drive level is increased by 10 log 79 x where x is equal to the desired channel load
