on the chip level, some think Si photonics optoelectronic chips are treated unfairly as all the standards are written in accordance to III-V materials. Some of these standards may not be absolutely necessary for use in practice. It's why most Si photonics products are used in AOC which only have end-to-end electrical specs. Hopefully big players like Intel, IBM can change it.

I think the battle of standards is in form factor. Both Cisco and Intel rolled out their own connectors to compete with existing MPO connector for highly parallel optics. Intel and IBM&Avago even wanted to completely eliminate all current panel mount transceivers module such as QSFP+, CFP, etc. which is a big threat to many component&module suppliers. We'll see how it goes.

First of all, it is not to be confused with 100G used in telecom which used advanced modulation to achieve serial 100Gb/s. It's for datacom 100G which can be 10x10Gb/s or 4x25Gb/s, the former was adopted earlier but slower and seems being replaced by the latter as 25G electronics are getting ready. Most early advocates of 10x10G shifted to 4x25G now. No matter for telecom 100G or for datacomm 100GBASE, no 100Gb/s electronics is actually used or needed.

I meant there are no standards specifically for silicon photonics

How about the 100G standard for optical network?

Wonderful article! What do you refer to by " there are no standards"? 100G standard is more mature than 40G, e.g. PM-QPSK modulation is the only one adopted in 100G,while there is no standard modulation method in 40G.

It looks like a lot of parallelism is needed for any electronics to match 100G/s.
