Appendix B SFP Transceiver Specifications
Table B-2 lists the fiber loss budgets for the 100-MB SFP transceivers.
Table B-3 lists the fiber loss budgets for the 1-GB SFP transceivers.
Note The maximum Rx indicates the overload threshold of the receiver. The minimum Rx indicates the lowest
acceptable signal level coming into the receiver that allows correct signal recognition.
