I have a question regarding the 1000Base-LX or SX standard. The question is mainly on the electrical characteristics of the output and input requirements of the 1000Base-X.
The standard is based on the IEEE 802.3z. After trying to read through the standard document, I couldn't figure out what is actually the output and input requirement of the 1000Base-LX/SX interface. In other words, what is the standard output to an optical transmitter and what is the standard input requirement from an optical receiver that conforms to 802.3z.
I'm fairly new to Ethernet and I have to admit, I dont quite understand all the wordings especially when I'm simply looking for the input/output standards. Thanks for any help in advance.
The reason I'm asking is because I'm developing a low-power receiver with differential output of VCM=0.2V and Vswing=0.2V (single ended), with SFP interface to interface it to a typical RJ45-SFP media converter (gigabit ethernet).
I need to know if my receiver output is compatible with the typically-used 1000BASE-X-compliant media converters out there. If it is not compatible, maybe I would need to use a limiting amp in my receiver to boost the signal, but I'd prefer to keep the limiting amp out to preserve my low-power spec.
