Table 2.3 Plug-in SFP Optical Transceiver Matrix
Note 1: This is strictly a dispersion limitation. Actual transmission distance is also dictated by the power budget
of each transmission link. EDFAs and dispersion compensation modules are suitable for use with
TR4580-xx-PI, TSD4580-xx-PI, and TKD4580-xx-PI transceivers and can be used to extend the
transmission range.
2.3.6
Pads and Equalizers
Plug-in pads (attenuators) and equalizers are used in forward path receivers and on the RF
amplifier to adjust the node’s RF levels.
On the RF amplifier tray, the position of specific pads determines segmentation. Pad values (in dB)
are used to adjust levels (see Appendix A, Table A-1).
Equalizers are used to insert a positive slope (with respect to frequency) to offset the negative slope
normally found in coax cable runs (see Appendix A, Table A-3).
See Foldout 1 at the back of this manual for the location of pads and equalizers on the OA4324HG
RF amplifier tray.
