摘要： Various example embodiments are disclosed. According to one example embodiment, a method may include transmitting a semiconductor laser-generated optical signal from a first end of a multi-mode fiber (MMF) optical link to a second end of the link. The optical signal may have a reference bandwidth at the first end of the link. The method may further include converting the optical signal to an electrical signal. The method may further include analyzing the electrical signal with an electronic dispersion compensator to determine an effective modal bandwidth (EMBW) of the received optical signal. The method may further include analyzing the electrical signal with an electronic dispersion compensator to determine an intersymbol interference (ISI) penalty of the optical link. The method may further include comparing the EMBW and the ISI penalty to predetermined threshold values of a tolerable EMBW and a tolerable ISI penalty, respectively, to characterize the optical link as acceptable or unacceptable for use as a communications link with a predetermined communications protocol.

摘要： A method is provided to lower the overall power consumption of small form-factor pluggable (SFP) transceivers. The method includes receiving an indication to operate the SFP transceiver in a low power mode, and setting the SFP transceiver to a low power mode in response to the indication by at least switching off a thermal electric cooler (TEC) that controls a temperature of a laser diode of the SFP transceiver. The proposed method may be implemented whenever a reach is not more than a predetermined distance, for example, 65 kilometers. At such reduced distances, the TEC of the SFP transceiver can be switched off while still guaranteeing link functionality. The instant low power mode has the benefit of reducing the power consumption of the SFP transceiver so that, for example, host platforms with lower power delivery budgets can support the SFP transceiver for at least some applications.
