1. 2 Connectors not in use should be covered over the ferrule by a plastic dust cap It is important to note that inside of the ferrule dust caps contains a sticky gelatinous residue that is the by product of the making of the dust cap This residue will remain on the ferrule end after the cap is removed Therefore it is critical that the ferrule end be cleaned thoroughly BEFORE it is mated to the intended unit FRRA Series Instruction Manual Troubleshooting Commercially available test equipment such as an Optical Signal Locator OSL is an effective tool for locating problems with the fiber optic cables The OSL can also be used to verify that the transmitter is indeed putting out light Other common problems include using a transmitter as a receiver and vice versa lack of continuity in the optical fiber lack of power or improper input levels If problems persist contact Blonder Tongue s Technical Solutions Department Problems and Comments Problem LED Status Check Comments Orange Optical Power LED Signal out of node is noisy Orange Optical Power LED No RF signal out of node Green Optical Power LED Status LED Green or Red No optical power at the Node Signal out of node is distorted Check power at the Tx Check optical power input via power monitor jack at the node Check the node power connection Check attenuator jumper installation Verify RF input signal on Tx Verify fiber2. Attenuator Selection The RF output level from the optical receiver module varies considerably over its operational optical input range It is also dependent upon the transmitter s channel loading its resultant RF input level and the FRRA s RF output capability In order not to overload the amplifier section input an attenuator must be installed in the RF Loop on the rear panel With the optical source and AC power connected measure the RF signal level at RF Loop output connector Choose the appropriate attenuator value to set this level to 5 dBmV 5 dB A Blonder Tongue model FAM xx Stock No 4006A xx or equivalent attenuator can be used for this application Install the attenuator on the RF loop output connector Check that the desired 5 dBmV nominal signal level has been obtained or change value accordingly Install a coaxial jumper between the attenuator and the RF Loop input Note that measured levels below 0 dBmvV without attenuator indicates a low optical input and should therefore be investigated The FRRA gain and slope controls can now be adjusted for desired output Model FRRA S4A 860P Ch Loadin 110 Ch Output Level 34 42 Optical Input dBm mW 10 0 10 Increase Optical Input Power 9 0 13 Orange Optical LED Indication 8 0 16 7 0 20 C _ 6 0 25 0 dB R __ 5 0 32 2 dB E 0 40 4 dB Approximate E 3 0 50 6 dB External N 2 0 63 8 dB Attenuator Value 1 0 79 10 dB Required L 0 1 00 12 dB E 1
